What does it really mean to be yourself at work without hiding, performing, or shrinking to fit expectations? In this Finding Brave conversation, we explore why authentic presence is not a soft skill or a personal indulgence, but a powerful leadership practice that builds trust, connection, and impact in today's fast-moving, emotionally complex workplaces.   Today's inspiring guest is Claude Silver, the world's first Chief Heart Officer at VaynerX, where she partners with CEO Gary Vaynerchuk to shape culture and leadership at scale. A sought-after speaker and the author of Be Yourself at Work: The Groundbreaking Power of Showing Up, Standing Out, and Leading from the Heart, Claude brings a deeply human lens to leadership that is grounded in emotional intelligence, courage, and self-awareness. Her work challenges the outdated belief that professionalism requires emotional distance or self-erasure. In this wide-ranging and deeply personal discussion, Claude shares formative stories from her own life that shaped her understanding of authentic presence. Together, Kathy and Claude unpack what authenticity looks like in real moments at work, from navigating difficult conversations to noticing the inner "song" that shapes how we show up. Claude breaks down her three emotional pillars, namely, emotional optimism, emotional bravery, and emotional efficiency, and explains how emotions can guide more grounded and courageous leadership. The episode also explores why leading with heart matters more than ever in an AI-driven, always-on world, and how taking up space, asking for what you need, and speaking honestly can transform both individual careers and workplace cultures. Listen in and consider what might shift if you gave yourself permission today to be fully seen and fully heard at work!   Key Highlights From This Episode: Introducing Claude Silver and what's missing from how we talk about authenticity.

Em abril deste ano foi anunciada a detecção de possíveis sinais de vida extraterrestre num planeta fora do sistema solar com o telescópio espacial James Webb, mas a descoberta não foi confirmada. Afinal, tem ou não tem vida nesse outro planeta? Que planeta é esse? Como é possível saber alguma coisa sobre um planeta distante? Este episódio do Oxigênio vai encarar essas questões com a ajuda de dois astrônomos especialistas no assunto: o Luan Ghezzi, da UFRJ, e a Aline Novais, da Universidade de Lund, na Suécia. Vamos saber um pouco mais sobre como é feita a busca por sinais de vida nas atmosferas de exoplanetas.  __________________________________________________________________________________________________ ROTEIRO Danilo: Você se lembra de quando uma possível detecção de sinais de vida extraterrestre virou notícia de destaque em abril deste ano, 2025? Se não, deixa eu refrescar a sua memória: usando o telescópio espacial James Webb, pesquisadores teriam captado sinais da atmosfera de um exoplaneta que indicariam a presença de um composto químico que aqui na Terra é produzido pela vida, algo que no jargão científico é chamado de bioassinatura.  A notícia bombou no mundo todo. Aqui no Brasil, o caso teve tanta repercussão que a Folha de São Paulo dedicou um editorial só para isso – os jornais costumam comentar política e economia nos editoriais, e raramente dão espaço para assuntos científicos. Nos dois meses seguintes, outros times de pesquisadores publicaram pelo menos quatro estudos analisando os mesmos dados coletados pelo James Webb e concluíram que as possíveis bioassinaturas desaparecem quando outros modelos são usados para interpretar os dados. Sem o mesmo entusiasmo, os jornais noticiaram essas refutações e logo o assunto sumiu da mídia. Afinal, o que aconteceu de fato? Tem ou não tem vida nesse outro planeta? Aliás, que planeta é esse? Como é possível saber alguma coisa sobre um planeta distante? Eu sou Danilo Albergaria, jornalista, historiador, e atualmente pesquiso justamente a comunicação da astrobiologia, essa área que estuda a origem, a evolução e a possível distribuição da vida no universo. Nesse episódio, com a ajuda de dois astrofísicos, o Luan Ghezzi e a Aline Novais, vou explicar como os astrofísicos fazem as suas descobertas e entender porque a busca por sinais de vida fora da Terra é tão complicada e cheia de incertezas. Esse é o primeiro episódio de uma série que vai tratar de temas relacionados à astrobiologia. [Vinheta] Danilo: Eu lembro que li a notícia quentinha, assim que ela saiu no New York Times, perto das dez da noite daquela quarta-feira, dia 16 de abril de 2025. No dia seguinte, acordei e fui checar meu Whatsapp, já imaginando a repercussão. Os grupos de amigos estavam pegando fogo com mensagens entusiasmadas, perguntas, piadas e memes. Os grupos de colegas pesquisadores, astrônomos e comunicadores de ciência, jornalistas de ciência, também tinham um monte de mensagens, mas o tom era diferente. Em vez de entusiasmo, o clima era de preocupação e um certo mau-humor: “de novo DMS no K2-18b fazendo muito barulho”, disse uma cientista. Outra desabafou: “eu tenho coisa melhor pra fazer do que ter que baixar a fervura disso com a imprensa”. Por que o mal-estar geral entre os cientistas? Já chego lá. Os cientistas eram colegas que eu tinha conhecido na Holanda, no tempo em que trabalhei como pesquisador na Universidade de Leiden. Lá eu pesquisei a comunicação da astrobiologia. Bem no comecinho do projeto – logo que eu cheguei lá, em setembro de 2023 – saiu a notícia de que um possível sinal de vida, um composto chamado sulfeto de dimetila, mais conhecido pela sigla DMS, havia sido detectado num planeta a 124 anos-luz de distância da Terra, o exoplaneta K2-18b. Eu vi a repercussão se desenrolando em tempo real: as primeiras notícias, os primeiros comentários críticos de outros cientistas, a discussão nas redes sociais e blogs. Como eu estava no departamento de astronomia de Leiden, vi também como isso aconteceu por dentro da comunidade científica: os astrônomos com quem conversei na época estavam perplexos com a forma espalhafatosa com que o resultado foi comunicado. O principal era: eles não estavam nem um pouco animados, otimistas mesmo de que se tratava, de verdade, da primeira detecção de vida extraterrestre. Por que isso estava acontecendo? Vamos começar a entender o porquê sabendo um pouco mais sobre o exoplaneta K2-18b, em que os possíveis sinais de vida teriam sido detectados. Primeiro: um exoplaneta é um planeta que não orbita o Sol, ou seja, é um planeta que está fora do sistema solar (por isso também são chamados de extrassolares). Existem planetas órfãos, que estão vagando sozinhos pelo espaço interestelar, e planetas girando em torno de objetos exóticos, como os pulsares, que são estrelas de nêutrons girando muito rápido, mas quando os astrônomos falam em exoplaneta, quase sempre estão falando sobre um planeta que gira em torno de outra estrela que não Sol. O Sol é uma estrela, obviamente, mas o contrário da frase geralmente a gente não ouve, mas que é verdade… as estrelas são como se fossem sóis, elas são sóis. As estrelas podem ser maiores, mais quentes e mais brilhantes do que o Sol – muitas das estrelas que vemos no céu noturno são assim. Mas as estrelas também podem ser menores, mais frias e menos brilhantes do que o Sol – as menores são chamadas de anãs vermelhas. Elas brilham tão pouco que não dá para vê-las no céu noturno a olho nu. O K2-18b é um planeta que gira em torno de uma dessas anãs vermelhas, a K2-18, uma estrela que tem menos da metade do tamanho do Sol. Só que o planeta é relativamente grande. Luan Ghezzi: Ele é um planeta que tem algo entre 8 e 9 vezes a massa da Terra, ou seja, é um planeta bem maior do que a Terra. E ele tem um raio ali aproximado de 2.6 vezes o raio da Terra. Então, com essa massa e com esse raio há uma dúvida se ele seria uma super-Terra, ou se ele seria o que a gente chama de Mini-Netuno, ou seja, super-Terra, são planetas terrestres, mas, porém, maiores do que a Terra. Mini-Netunos são planetas parecidos com o Netuno. Só que menores. Mas com essa junção de massa e raio, a gente consegue calcular a densidade. E aí essa densidade indicaria um valor entre a densidade da Terra e de Netuno. Então tudo indica que esse K2-18b estaria aí nesse regime dos mini-Netunos, que é uma classe de planetas que a gente não tem no sistema solar. Danilo: Netuno é um gigante gelado e ele tem uma estrutura muito diferente da Terra, uma estrutura que (junto com o fato de estar muito distante do Sol) o torna inabitável, inabitável à vida como a gente a conhece. Mini-Netunos e Super-Terras, de tamanho e massa intermediários entre a Terra e Netuno, não existem no sistema solar, mas são a maioria entre os mais de 6 mil exoplanetas descobertos até agora.  A estrela-mãe do K2-18b é bem mais fria, ou menos quente do que o Sol: enquanto o Sol tem uma temperatura média de 5500 graus Celsius, a temperatura da K2-18 não chega a 3200 graus. Então, se a gente imaginasse que o Sol fosse “frio” assim (frio entre aspas), a temperatura aqui na superfície da Terra seria muito, mas muito abaixo de zero, o que provavelmente tornaria nosso planeta inabitável. Só que o K2-18b gira muito mais perto de sua estrela-mãe. A distância média da Terra para o Sol é de aproximadamente 150 milhões de quilômetros, enquanto a distância média que separa o K2-18b e sua estrela é de 24 milhões de quilômetros. Outra medida ajuda a entender melhor como a órbita desse planeta é menor do que a da Terra: a cada 33 dias, ele completa uma volta ao redor da estrela. E comparado com a estrela, o planeta é tão pequeno, tão obscuro, que não pode ser observado diretamente. Nenhum telescópio atual é capaz de fazer imagens desse exoplaneta, assim como acontece com quase todos os exoplanetas descobertos até agora. São muito pequenos e facilmente ofuscados pelas estrelas que orbitam. Como, então, os astrônomos sabem que eles existem? O Luan Ghezzi explica. Luan Ghezzi: a detecção de exoplanetas é um processo que não é simples, porque os planetas são ofuscados pelas estrelas deles. Então é muito difícil a gente conseguir observar planetas diretamente,  você ver o planeta com uma imagem… cerca de um por cento dos mais de seis mil planetas que a gente conhece hoje foram detectados através do método de imageamento direto, que é realmente você apontar o telescópio, e você obtém uma imagem da estrela e do planeta ali, pertinho dela. Todos os outros planetas, ou seja, noventa e nove porcento dos que a gente conhece hoje foram detectados através de métodos indiretos, ou seja, a gente detecta o planeta a partir de alguma influência na estrela ou em alguma propriedade da estrela. Então, por exemplo, falando sobre o método de trânsito, que é com que mais se descobriu planetas até hoje, mais de setenta e cinco dos planetas que a gente conhece. Ele é um método em que o planeta passa na frente da estrela. E aí, quando esse planeta passa na frente da estrela, ele tampa uma parte dela. Então isso faz com que o brilho dela diminua um pouquinho e a gente consegue medir essa variação no brilho da estrela. A gente vai monitorando o brilho dela. E aí, de repente, a gente percebe uma queda e a gente fala. Bom, de repente passou alguma coisa ali na frente. Vamos continuar monitorando essa estrela. E aí, daqui a pouco, depois de um tempo, tem uma nova queda. A diminuição do brilho e a gente vai monitorando. E a gente percebe que isso é um fenômeno periódico. Ou seja, a cada x dias, dez dias, vinte dias ou alguma coisa do tipo, a gente tem aquela mesma diminuição do brilho ali na estrela. Então a gente infere a presença de um planeta ali ao redor dela. E aí, como são o planeta e a estrela um, o planeta passando na frente da estrela, tem uma relação entre os tamanhos. Quanto maior o planeta for, ele vai bloquear mais luz da estrela. Então, a partir disso, a gente consegue medir o raio do planeta. Então esse método do trânsito não só permite que a gente descubra os exoplanetas, como a gente também pode ter uma informação a respeito dos raios deles. Esse é o método que está sendo bastante usado e que produziu mais descobertas até hoje. Danilo: e foi por esse método que o K2-18b foi descoberto em 2015 com o telescópio espacial Kepler. Esse telescópio foi lançado em 2009 e revolucionou a área – com o Kepler, mais de 2700 exoplanetas foram detectados. Com ele, os astrônomos puderam estimar que existem mais planetas do que estrelas na nossa galáxia.  A órbita do K2-18b é menor do que a do planeta Mercúrio, que completa uma volta ao redor do Sol a cada 88 dias terrestres. Mas como sua estrela-mãe é mais fria do que o Sol, isso coloca o K2-18b dentro do que os astrônomos chamam de zona habitável: nem tão longe da estrela para que a superfície esfrie a ponto de congelar a água, nem tão perto para que o calor a evapore; é a distância ideal para que a água permaneça em estado líquido na superfície de um planeta parecido com a Terra. Só que o estado da água depende de outros parâmetros, como a pressão atmosférica, por exemplo. E é por isso que a tal da zona habitável é um conceito muito limitado, que pode se tornar até mesmo enganoso: um planeta estar na zona habitável não significa que ele seja de fato habitável. Claro, estar na zona habitável é uma das condições necessárias para que a superfície de um planeta tenha água líquida, o que é fundamental para que essa superfície seja habitável. Ter uma atmosfera é outra condição necessária. Além de estar na zona habitável, o K2-18b tem atmosfera e o Luan também explica como os astrônomos fazem para saber se um exoplaneta como o K2-18b tem uma atmosfera. Luan: a gente estava falando sobre o método de trânsito. E a gente falou que o planeta passa na frente da estrela e bloqueia uma parte da luz dela. Beleza, isso aí a gente já deixou estabelecido. Mas se esse planeta tem uma atmosfera, a luz da estrela que vai atingir essa parte da atmosfera não vai ser completamente bloqueada. A luz da estrela vai atravessar a atmosfera e vai ser transmitida através dela. A gente tem essa parte bloqueada da luz que a gente não recebe, a gente percebe a diminuição de brilho da estrela, com o método de trânsito, mas tem essa luz que atravessa a atmosfera e chega até a gente depois de interagir com os componentes da atmosfera daquele planeta. Então a gente pode analisar essa luz, que é transmitida através da atmosfera do planeta para obter informações sobre a composição dela. Danilo: e como é possível saber a composição química dessa atmosfera? A Aline Novais é uma astrofísica brasileira fazendo pós-doutorado na Universidade de Lund, na Suécia. A tese de doutorado dela, orientada pelo Luan, foi exatamente sobre esse tema: a coleta e a análise dos dados de espectroscopia de atmosferas de exoplanetas. Aline: No início, a gente não está olhando uma foto, uma imagem dos planetas e das estrelas. A gente está vendo eles através de uma coisa que a gente chama de espectro, que é a luz da estrela ou do planeta em diferentes comprimentos de onda. O que é o comprimento de onda? É literalmente o tamanho da onda. Você pode ver também como se fossem cores diferentes. Então a gente vai estar vendo vários detalhes em diferentes comprimentos de onda. O que acontece? A gente já sabe, não da astronomia, mas da química de estudos bem antigos que determinados compostos, vou usar aqui, por exemplo, a água, ela vai ter linhas muito específicas em determinados comprimentos de onda que a gente já conhece, que a gente já sabe. Então já é estabelecido que no cumprimento de onda X, Y, Z, vai ter linha de água. Então, quando a gente está observando novamente o brilho da estrela que passou ali pela atmosfera do planeta. Interagiu com o que tem lá, que a gente não sabe. Quando a gente vê o espectro dessa estrela que passou pela atmosfera, a gente vai poder comparar com o que a gente já sabe. Então, por exemplo, o que a gente já sabe da água, a gente vai ver que vai bater. É como se fosse um código de barras. Bate certinho o que tem na estrela, no planeta e o que tem aqui na Terra. E aí, a partir disso, a gente consegue dizer: “Ah, provavelmente tem água naquele planeta.” Claro que não é tão simples, tão preto no branco, porque tem muitas moléculas, muitos átomos, a quantidade de moléculas que tem ali também interferem nessas linhas. Mas, de forma mais geral, é isso. A gente compara um com o outro. E a gente fala: essa assinatura aqui tem que ser de água. Danilo: Em setembro de 2023, o time de pesquisadores liderado pelo Nikku Madhusudhan, da Universidade de Cambridge, na Inglaterra, anunciou a caracterização atmosférica do K2-18b feita com o telescópio espacial James Webb. Alguns anos antes, a atmosfera do exoplaneta tinha sido observada com o telescópio espacial Hubble, que havia indicado a presença de vapor de água. Com o James Webb, esses cientistas concluíram que a atmosfera não tinha vapor de água, mas fortes indícios de metano e dióxido de carbono, o gás carbônico. Não só isso: no mesmo estudo, eles também alegaram ter detectado, com menor grau de confiança, o sulfeto de dimetila, também chamado de DMS, uma molécula orgânica que aqui na Terra é produzida pela vida marinha, principalmente pelos fitoplânctons e microalgas. O DMS pode ser produzido em laboratório mas não existe um processo natural em que o nosso planeta, sozinho, consiga fazer essa molécula sem envolver a vida. Ou seja, o DMS seria uma possível bioassinatura, um sinal indireto da existência de vida. Por isso, esses cientistas alegaram ter encontrado uma possível evidência de vida na atmosfera do K2-18b. O fato é que a suposta evidência de vida, a detecção de DMS lá de 2023, tinha um grau de confiança estatística muito baixo para contar seriamente como evidência de vida. O time liderado pelo Madhusudhan continuou observando o K2-18b e voltou a publicar resultados apontando a presença de DMS usando outros instrumentos do James Webb. Foram esses resultados que fizeram tanto barulho em abril de 2025. E por que tanto barulho? Porque esse novo estudo apresenta um grau de confiança estatística mais alto para a detecção de DMS. Ele também alega ter detectado outra possível bioassinatura, uma molécula aparentada ao DMS, o DMDS, ou dissulfeto de dimetila. O resultado pareceu reforçar muito a hipótese da presença dessas possíveis bioassinaturas no K2-18b e, por isso, os grandes meios de comunicação deram ainda mais atenção ao resultado do que há dois anos atrás. O problema é que é muito complicado analisar os resultados do James Webb sobre essas atmosferas, e ainda mais difícil cravar a presença desse ou daquele composto químico ali. Aline Novais: Acho que a primeira etapa mais difícil de todas é como você tinha falado, Danilo, é separar o que é a luz do planeta e o que é a luz da estrela. Quer dizer, da atmosfera do planeta e o que é luz da estrela. E isso a gente faz como quando a gente está observando o trânsito. A gente não só observa o planeta passando na frente da estrela. Mas a gente também observa a estrela sem o planeta, e a gente compara esses dois. É literalmente subtrair um do outro. Então, assim, supondo que a gente já tem aqui o espectro pronto na nossa frente. O que a gente vai fazer para entender o que está naquele espectro? Aquilo ali é uma observação. Só que a gente tem da teoria da física, a gente sabe mais ou menos quais são as equações que vão reger a atmosfera de um planeta. Então a gente sabe o que acontece de formas gerais, que é parecida com o que acontece aqui na Terra e com o planeta do sistema solar. Então a gente sabe mais ou menos como deve ser a pressão, a temperatura. A gente sabe mais ou menos quais compostos químicos vão ter em cada camada da atmosfera, que depende de várias coisas. A gente sabe que se um planeta está muito próximo da estrela, ele vai ter determinados compostos químicos que ele não teria se ele estivesse muito mais longe da estrela dele. Então tudo isso interfere. E aí, o que a gente faz? A gente tem os dados, a gente tem o que a gente observou no telescópio. E a gente vai comparar com a teoria, com modelos que a gente faz no computador, programando, parará, parará, que vão reger aquela atmosfera. E aí, a partir disso, a gente vai comparar e ver o que faz sentido, o que não faz, o que bate e o que não bate. Danilo: Notaram que a Aline ressalta o papel dos modelos teóricos na interpretação dos dados? Os astrônomos comparam os dados coletados pelo telescópio com o que esperam observar, orientados pelas teorias e modelos considerados promissores para representar o que de fato está lá na atmosfera do planeta. E é nessa comparação que entra a estatística, a probabilidade de que as observações correspondem a este ou aquele modelo teórico. Aline Novais: Na estatística, a gente sempre vai estar quando a gente tiver probabilidade de alguma coisa, a gente sempre vai estar comparando uma coisa X com uma coisa Y. A gente nunca vai ter uma estatística falando que sim ou que não, vai ser sempre uma comparação de uma coisa ou de outra. Então, quando a gente, por exemplo, a gente tem o espectro lá de um planeta, a gente tem assinaturas que provavelmente podem ser de água, mas vamos supor que essa assinatura também é muito parecida com algum outro elemento. Com algum outro composto químico. O que a gente vai fazer? A gente vai comparar os dois e a resposta não vai ser nem que sim nem que não. A resposta vai ser: “Ah, o modelo que tem água é mais favorável.” Ou então, ele ajusta melhor os dados, do que o modelo com aquele outro composto químico.  Danilo: O time do Nikku Madhusudhan, que fala em possível detecção de DMS, tem um modelo predileto que eles mesmos desenvolveram para explicar planetas como o K2-18b: os mundos hiceanos, planetas inteiramente cobertos por um oceano de água líquida debaixo de uma espessa atmosfera de hidrogênio molecular – por isso o nome, que é uma junção do “hi” de hidrogênio e “ceano” de oceano. É esse modelo que orienta a interpretação de que os dados do K2-18b podem conter as bioassinaturas.  Aline: Todo o resultado final, que é: possivelmente detectamos assinaturas, não dependem dos dados em si, mas dependem de como eles analisaram os dados e que modelos foram utilizados para analisar esses dados. […] Os resultados vão sempre depender de como a gente analisou esses dados. […] Então a questão da detecção, ou possível detecção de bioassinatura depende principalmente de como foram colocados os modelos, do que foi inserido nos modelos e como esses modelos foram comparados. Nesse caso, os modelos utilizados foram modelos que estavam supondo que o planeta era hiceano. Que o planeta tinha um oceano e tinha uma atmosfera de hidrogênio, majoritariamente de hidrogênio. Porém, outros estudos levantaram também a possibilidade de esse planeta não ser desse tipo, ser um planeta, por exemplo, coberto de lava e não de oceano, ou com uma atmosfera, com compostos diferentes, onde a maioria não seria hidrogênio, por exemplo. E esses modelos não foram utilizados para testar essas bioassinaturas. Então o que acontece: no modelo deles, com o oceano, com a atmosfera X, Y e Z, é compatível com a existência de bioassinaturas. Porém, é completamente dependente do modelo.  Danilo: Então, a escolha de modelos teóricos diferentes afetam a interpretação dos resultados e das conclusões sobre a composição química da atmosfera de exoplanetas.  Aline: Esse grupo acredita que o planeta tenha majoritariamente hidrogênio na sua composição. O que eles vão fazer no modelo deles? Eles vão colocar sei lá quantos por cento de hidrogênio na composição, no modelo deles. Então eles estão construindo um modelo que seja semelhante ao que eles acreditam que o planeta tem. Eu não vou colocar nitrogênio se eu acho que não tem nitrogênio. Então, aí que entra a controvérsia, que é justamente o modelo ser feito para encontrar o que eles tentam encontrar. Então, assim, se você pegasse um modelo completamente diferente, se você pegasse um modelo, por exemplo, de um planeta feito de lava, que tem metano, que tem isso, que tem aquilo, será que você encontraria a mesma coisa? Danilo: Saber qual modelo teórico de atmosferas de exoplanetas corresponde melhor à realidade é algo muito difícil. O que dá pra fazer é comparar os modelos entre si: qual deles representa melhor a atmosfera do exoplaneta em comparação com outro modelo. Aline: A gente nunca vai estar falando que o modelo é perfeito. A gente nunca vai estar falando que a atmosfera é assim. A gente sempre vai estar falando que esse modelo representa melhor a atmosfera do que um outro modelo. E se você pegar uma coisa muito ruim que não tem nada a ver e comparar com uma coisa que funciona, vai ser muito fácil você falar que aquele modelo funciona melhor, certo? Então, por exemplo, no caso do K2-18b: eles fizeram um modelo que tinha lá as moléculas, o DMS, o DMDS e tal, e compararam aquilo com um modelo que não tem DMS e DMDS. O modelo que tem falou “pô, esse modelo aqui se ajusta melhor aos dados do telescópio do que esse outro que não tem”. Mas isso não significa que tenha aquelas moléculas. Isso significa que aquele modelo, naquelas circunstâncias, foi melhor estatisticamente do que um modelo que não tinha aquelas moléculas.  Danilo: O Luan tem uma analogia interessante pra explicar isso que a Aline falou. Luan: É como se você, por exemplo, vai em uma loja e vai experimentar uma roupa. Aí você pega lá uma mesma blusa igualzinha, P, M ou G. Você experimenta as três e você vê qual que você acha que se ajusta melhor ao seu corpo, né? Qual ficou com um caimento melhor? Enfim, então você vai fazendo essas comparações, não é que a blusa talvez M não tenha ficado boa, mas talvez a P ou a G tenha ficado melhor. Então os modelos são agitados dessa forma, mas também como a Aline falou depois que você descobriu o tamanho, por exemplo, você chegou à conclusão que o tamanho da blusa é M, você pode pegar e escolher diferentes variações de cores. Você pode pegar essa mesma blusa M, azul, verde, amarela, vermelha, né? E aí elas podem fornecer igualmente o mesmo bom ajuste no seu corpo. Só que a questão é que tem cores diferentes. […] A gente obviamente usa os modelos mais completos que a gente tem hoje em dia, mas não necessariamente, eles são hoje mais completos, mas não necessariamente eles são cem por cento completos. De repente está faltando alguma coisa ali que a gente não sabe.  [Música] Danilo: Eu conversei pessoalmente com o líder do time de cientistas que alegou ter descoberto as possíveis bioassinaturas no K2-18b, o Nikku Madhusudhan, quando ele estava na Holanda para participar de uma conferência em junho de 2024. Ele pareceu entusiasmado com a possibilidade de vir a confirmar possíveis bioassinaturas em exoplanetas e ao mesmo tempo cuidadoso, aparentemente consciente do risco de se comunicar a descoberta de vida extraterrestre prematuramente. A questão é que ele já cometeu alguns deslizes na comunicação com o público: por exemplo, em abril de 2024, num programa de rádio na Inglaterra, ele disse que a chance de ter descoberto vida no K2-18b era de 50% – o próprio apresentador do programa ficou surpreso com a estimativa. Naquela mesma conferência da Holanda, o Madhusudhan também pareceu muito confiante ao falar do assunto com o público de especialistas em exoplanetas – ele sabia que enfrentava muitos céticos na plateia. Ele disse que os planetas hiceanos eram “a melhor aposta” que temos com a tecnologia atual para descobrir vida extraterrestre.   Na palestra em que apresentou os novos resultados esse ano, o Madhusudhan contou que essa hipótese de mundos hiceanos foi desenvolvida com a ajuda de alunos de pós-graduação dele quando ele os desafiou a criar um modelo teórico de Mini-Netuno que oferecesse condições habitáveis, amenas para a vida. Mas a questão é que a gente não sabe se os mundos hiceanos sequer existem. É uma alternativa, uma hipótese para explicar o pouco que sabemos sobre esses exoplanetas. Há outras hipóteses, tão promissoras quanto essa, e muito menos amigáveis à existência da vida como a conhecemos. Enfim, a gente ainda sabe muito pouco sobre esses exoplanetas. Ainda não dá para decidir qual hipótese é a que melhor descreve a estrutura deles. Mas o que vai acontecer se algum dia os cientistas conseguirem resultados que apontem para uma detecção de possível bioassinatura que seja num alto grau de confiança, a tal ponto que seria insensato duvidar de sua existência? Estaríamos diante de uma incontroversa descoberta de vida extraterrestre? Digamos que os cientistas publiquem, daqui a algum tempo, novos resultados que apontam, com um grau de confiança altíssimo, para a presença de DMS no K2-18b. Mesmo que a gente tivesse certeza de que tem DMS naquela atmosfera, não seria possível cravar que a presença de DMS é causada pela vida. Como a gente tem ainda muito pouca informação sobre os ambientes que os Mini-Netunos podem apresentar, e como o nosso conhecimento sobre a própria vida ainda é muito limitado, vai ser muito difícil – para não dizer praticamente impossível – ter certeza de que a presença de uma possível bioassinatura é de fato uma bioassinatura.  Luan: A gente sabe que aqui na Terra, o DMS e o DMDS estão associados a processos biológicos. Mas a gente está falando de um planeta que é um Mini-Netuno, talvez um planeta hiceano. Será que esse planeta não tem processos químicos diferentes que podem gerar essas moléculas sem a presença da vida?  Danilo: Como disse o Luan, pode ser que processos naturais desconhecidos, sem o envolvimento da vida, sejam os responsáveis pela presença de DMS no K2-18b. A gente sabe que o DMS pode ser gerado fora da Terra por processos naturais, sem relação com a presença de vida. Para que seja gerado assim, são necessárias condições muito diferentes das que temos aqui na Terra. O interior de planetas gigantes como Júpiter, por exemplo, dá essas condições. DMS também foi detectado recentemente na superfície de um cometa, em condições muito hostis para a vida como a gente a conhece. Mais hostis ainda são as condições do meio interestelar, o espaço abissal e incrivelmente frio que existe entre as estrelas. Mesmo assim, DMS já foi detectado no meio interestelar.  É por isso que detectar uma possível bioassinatura num exoplaneta não necessariamente responde à pergunta sobre vida fora da Terra. É mais útil pensar nesses dados como peças de um quebra-cabeças: uma possível bioassinatura em um exoplaneta é uma peça que pode vir a ajudar a montar o quebra-cabeças em que a grande questão é se existe ou não existe vida fora da Terra, mas dificilmente será, sozinha, a resposta definitiva. Luan: Será que as bioassinaturas efetivamente foram produzidas por vida? Então, primeiro, estudos para entender diversos processos químicos ou físicos que poderiam gerar essas moléculas, que a gente considera como bioassinaturas, pra tentar entender em outros contextos, se elas seriam produzidas sem a presença de vida. Mas fora isso, nós astrônomos, nós também tentamos procurar conjuntos de bioassinaturas. Porque se você acha só o DMS ou o DMDS é uma coisa. Agora, se você acha isso e mais o oxigênio ou mais outra coisa, aí as evidências começam a ficar mais fortes. Um par muito comum que o pessoal comenta é você achar metano e oxigênio numa atmosfera de exoplaneta. Por quê? Porque esses dois compostos, se você deixar eles lá na atmosfera do planeta sem nenhum tipo de processo biológico, eles vão reagir. Vão formar água e gás carbônico. Então, se você detecta quantidades apreciáveis de metano e oxigênio numa atmosfera, isso indica que você tem algum processo biológico ali, repondo constantemente esses componentes na atmosfera. Então, a gente vai tentando buscar por pares ou conjuntos de bioassinaturas, porque isso vai construindo um cenário mais forte. Você olha, esse planeta está na zona habitável. Ele tem uma massa parecida com a da Terra. Ele tem uma temperatura parecida com a da Terra. Ele tem conjuntos de bioassinaturas que poderiam indicar a presença de vida. Então você vai construindo um quebra-cabeça ali, tentando chegar num conjunto de evidências.  Danilo: Talvez só vamos conseguir ter certeza quando tivermos condições de viajar os 124 anos-luz que nos separam do K2-18b, por exemplo, para examinar o planeta “in situ”, ou seja, lá no local – só que isso ainda é assunto para a ficção científica, não para a ciência atual. Não quer dizer que, dada a dificuldade, a gente deva desistir de fazer ciência nesse sentido, de detectar bioassinaturas nos exoplanetas. Luan: É claro que é super interessante aplicar esses modelos e sugerir a possível existência dessas moléculas. Isso ajuda a avançar o conhecimento, porque isso gera um interesse, gera um debate, um monte de gente vai testar, e outras pessoas já testaram e mostraram que, ou não tem a molécula nos modelos deles, ou eles não detectam ou detectam uma quantidade muito baixa. Enfim, então isso gera um debate que vai avançar o conhecimento. Então isso, no meio científico, é muito interessante esse debate, que gera outras pesquisas, e todo mundo tentando olhar por diferentes ângulos, para a gente tentar entender de uma maneira mais completa. Mas o cuidado… E aí, o grande serviço que o seu podcast está fazendo é como a gente faz chegar essa informação no público, que é o que você falou, uma coisa é: utilizamos um modelo super específico, e esse modelo indica a possível presença dessas moléculas que, na Terra, são associadas à vida. Outra coisa é dizer, na imprensa, achamos os sinais mais fortes de vida até agora. É uma distância muito grande entre essas duas coisas. Aline: Se eu analisei o meu dado e eu vi que tem aquela molécula de bioassinatura, uma coisa é eu falar: “Tem!” Outra coisa é falar: “Ó, eu analisei com esse modelo aqui e esse modelo aqui faz sentido. Ele representa melhor os meus dados do que o outro modelo”. São maneiras diferentes de falar. Mas qual que é a que vende mais? Danilo: Foi no final do nosso papo que o Luan e a Aline tocaram nessa questão que tem se tornado central nos últimos anos: como comunicar os resultados da astrobiologia da forma mais responsável? É possível que com o James Webb vamos continuar vendo potenciais detecções de bioassinaturas num futuro próximo. Por isso, a comunidade científica está preocupada com a forma como comunicamos os resultados da busca por vida fora da Terra e está se movimentando para contornar os problemas que provavelmente teremos no futuro. Eu venho participando desses esforços, pesquisando como a astrobiologia está sendo comunicada, e até ajudei a organizar um evento no ano passado para discutir isso com cientistas e jornalistas de ciência, mas conto essa história em outra hora. No próximo episódio, vamos falar sobre uma possível detecção de bioassinatura sem o James Webb e muito mais próxima da gente. A notícia veio em setembro de 2025. O planeta em que a bioassinatura pode ter sido encontrada? O vizinho cósmico que mais alimentou a imaginação humana sobre extraterrestres: Marte.

In dieser Folge widmen sich Franzi und Karl dem Feedback zu den letzten Geschichten im AstroGeo Podcast. Besonders schön war eine E-Mail von einer österreichischen Alm, mit Milchstraße, Satelliten und kindlichem Staunen über das „Mittendrinsein“ im Weltall. Danach geht es zurück zu den Schwarzen Löchern und der Frage, warum eine Astronautin am Ereignishorizont von außen so wirkt, als sei sie eingefroren. Daneben geht es um Singularitäten, Gravitation und der Frage, was wir wirklich „sehen“, wenn wir die neuen Bilder Schwarzer Löcher betrachten. Ausführlich wird über den Mars gesprochen: dessen dünne Atmosphäre, reale und mögliche Fluggeräte, die chemische Zusammensetzung und historische Irrtümer. Zuletzt geht es um die Besiedlung des Roten Planeten: Karl zweifelt am vermeintlich wirtschaftlichen Geschäftsmodell von SpaceX, das nebenbei diverse dramatische Folgen das Gemeinwohl auf der Erde hat, darunter zunehmend mehr Aluminium in der Atmosphäre, ein übervoller Erdorbit, das über Gebühr genutzte Frequenzspektrum oder die „Bestreifung“ astronomischer Beobachtungen – und das sogar für Weltraumteleskope wie Hubble. Es geht also um die fehlende Nachhaltigkeit von SpaceX – aber noch mehr: Karl erzählt vom Buch „A City on Mars“, das von der menschlichen Fortpflanzung jenseits der Erde handelt, die bis heute zahlreiche biologische und damit auch ethische Fragen aufwirft. Auch zu Franzis Folge über das Ende des Universums gibt es Fragen: Es geht um Big Rip, Big Crunch, Big Freeze oder ob der Urknall eigentlich durch die bekannten Naturgesetze ausgelöst wurde. Es geht auch darum, ob im Podcast abseitige wissenschaftliche Hypothesen vorgestellt werden sollten – und wo Franzi und Karl ihre Rolle als Journalisten sehen – und wo nicht. Bild vom Burger-Menü Karl beantwortet Fragen zu Sodom und Gomorra und dem vermeintlichen Luftzerplatzer eines Meteoriten in der Bronzezeit: Hörende erzählen vom real existierenden Peer Review oder ihre Erfahrung mit Bibeltexten. Zuletzt geht es um Feuersteine und Donnerkeile, eine besonders isländische Lieblingskarte aus dem Kartenspiel Magic und wie man AstroGeo ganz ohne Feedbackfolgen hören kann (über diesen Spezialfeed).

SHOW 12-9-25 CBS EYE ON THE WORLD WITH JOHN BATCHELOR 1916 MONTENEGRO THE SHOW BEGINS IN THE DOUBTS ABOUT THE HUBBLE CONSTANT. FIRST HOUR 9-915 Baltic Defenses and NATO's Uncertain Resolve: Colleague Blaine Holt discusses the Baltics preparing defensive "Mino lines" and bunkers fearing a potential Russian attack, noting Baltic citizens feel trapped between NATO bureaucracy and Russian hybrid warfare while doubting NATO's resolve to intervene, arguing diplomatic solutions are necessary as Europe lacks resources for a cohesive defense. 915-930 NATO's Viability and Europe's Demographic Shifts: Colleague Blaine Holt questions NATO's viability through 2050, citing rising US sentiment to withdraw and Europe's demographic shifts due to mass migration, warning that diverging values and economic instability could lead to civil unrest or new geopolitical alignments between Russia, China, and the US. 930-945 European Leaders Meet Zelenskyy Amid Strategic Dilemmas: Colleague Judy Dempsey discusses the "Big Three" European leaders meeting Zelenskyy, questioning their ability to resolve the war without wider coalitions, noting the EU is bypassing unanimity rules to seize Russian assets but struggles with the dilemma of offering Ukraine EU membership while demanding territorial concessions. 945-1000 Europe's Lack of Self-Confidence Facing Global Challenges: Colleague Judy Dempsey criticizes Europe's lack of self-confidence and ambition when facing Trump's transactional administration and Chinese aggression, arguing European leaders complain about US criticism rather than leveraging their own economic power, noting they are "sleepwalking" regarding the auto industry and dependencies on China. SECOND HOUR 10-1015 The National Security Strategy and the First Island Chain: Colleague Steve Yates analyzes the National Security Strategy's focus on the "first island chain" and deterrence against China's bullying of Japan and the Philippines, noting the CCP's obsession with WWII-era Japan for propaganda fails to resonate regionally as neighbors face modern Chinese aggression and grey zone tactics. 1015-1030 Nvidia Chip Sales to China Raise National Security Concerns: Colleague Brandon Weichert reports on the Trump administration approving Nvidia H200 chip sales to China while taking a 25% cut, warning this transactional approach compromises national security by aiding China's military AI, signaling a shift from hawkish policies to favoring business interests like soybeans. 1030-1045 SpaceX Dominance and the Golden Dome Defense Project: Colleague Bob Zimmerman highlights SpaceX's dominance with record-breaking booster reuse and launch frequency compared to rivals, discussing the secretive "Golden Dome" defense project, defects on the Orion capsule's hatch threatening the Artemis mission, and Airbus surprisingly choosing a Chinese satellite constellation for in-flight internet. 1045-1100 Cosmological Crises and Mars Rover Progress: Colleague Bob Zimmerman details cosmological crises including the "Hubble tension" where expansion rates conflict and a baffling 7-hour gamma-ray burst, reporting on Comet Tsuchinshan-ATLAS images confirming it is a comet rather than a spacecraft, and the Perseverance rover moving toward promising mining terrain on Mars.           THIRD HOUR 1100-1115 The 1605 Gunpowder Plot and Catholic Desperation: Colleague Claire Jackson explains the 1605 Gunpowder Plot as a desperate attempt by Catholics, frustrated by James I's retention of penal laws and peace with Spain, to destroy the Protestant establishment, with the plotters aiming to kill the king and install a puppet Catholic monarch amidst the ensuing chaos. 1115-1130 The Mirror of Great Britain and James I's Violent Childhood: Colleague Claire Jackson explains the "Mirror of Great Britain" jewel symbolizing James I's union plans, though it was destroyed during the Civil Wars, detailing his violent childhood in Scotland, his father Darnley's murder, and his separation from his mother Mary Queen of Scots, which shaped his intellectual upbringing. 1130-1145 The Hampton Court Conference and the King James Bible: Colleague Claire Jackson describes how James I convened the Hampton Court Conference to resolve religious differences, resulting in the King James Bible, highlighting his unique role as an author of works like Basilikon Doron, using print to converse with subjects and establish the divine right of kings. 1145-1200 James I as Ecumenicist Amid Confessional Complexity: Colleague Claire Jackson portrays James I as an ecumenicist seeking accommodation, provided Catholics recognized his temporal authority via an Oath of Allegiance, noting he faced a "confessional complexity" ruling Protestant Scotland and England alongside Catholic Ireland, aiming to isolate radical Jesuits from the loyal majority. FOURTH HOUR 12-1215 Commodities Update from France: Colleague Simon Constable reports from France on unseasonably warm weather and rising copper prices driven by tech demand, noting cocoa prices dropped while coffee remains expensive, discussing farmers' effective non-violent protests in Europe and contrasting European energy shortages with the electricity needs of AI development. 1215-1230 UK Labour's Struggles and the Workers' Rights Bill: Colleague Simon Constable analyzes the UK Labour Party's struggles despite a large majority, citing Keir Starmer's low approval, warning that the return of "Red Rayner" and a new workers' rights bill preventing easy firing could stifle economic growth and deter foreign investment, worsening Britain's debt. 1230-1245 The National Security Strategy as Transatlantic "Divorce Papers": Colleague Blaine Holt argues the National Security Strategy resembles "divorce papers" for a perilous transatlantic relationship, contending Europe, having de-industrialized, refuses Trump's diplomatic efforts to end the Ukraine war, fearing the aftermath of a conflict they cannot sustain against a re-industrialized Russia. 1245-100 AM Penang's Boom Contrasts with China's Decline: Colleague Charles Ortel contrasts Penang's economic boom and diverse hardworking culture with China's decline, discussing China's suppressed financial data and property crisis with Gordon Chang, arguing Western elites were "bought off" by Beijing while investors should demand transparency regarding assets trapped in ChiNA.

Cosmological Crises and Mars Rover Progress: Colleague Bob Zimmerman details cosmological crises including the "Hubble tension" where expansion rates conflict and a baffling 7-hour gamma-ray burst, reporting on Comet Tsuchinshan-ATLAS images confirming it is a comet rather than a spacecraft, and the Perseverance rover moving toward promising mining terrain on Mars. 1865

s of the Hubble Constant — Bob Zimmerman — Zimmerman outlines a fundamental crisis in cosmological understanding regarding the Hubble constant, the astronomical parameter measuring the rate at which the universe is systematically expanding across time and space. Zimmerman documents that the measurement crisis stems from irreducible conflicting empirical data: when astronomers measure the early universe using distant supernovae and cosmic microwave background radiation, they derive a lower expansion rate number, yet when they measure the near universeusing contemporary observations of local galactic clusters, they derive a significantly higher expansion rate number. Zimmerman emphasizes that this discrepancy does not result from imprecise or unreliable data; rather, both measurement methodologies have become increasingly sophisticated and accurate, yet the fundamental contradiction persists despite technological improvements. Zimmerman argues that the persistent contradiction between two highly accurate but incompatible numerical values indicates that "something is fundamentally wrong with the cosmology and the theories," suggesting that current scientific understanding of the Big Bang, cosmic evolution, and the universe's fundamental physical properties contains critical errors requiring radical theoretical revision. Zimmerman employs an analogy: if measuring a child's growth rate during their first year of life predicted they should be 4 feet tall, but contemporary measurement reveals them to be 5 feet tall, and both measurements are perfectly accurate, then the mathematical formula governing human growth is fundamentally flawed—similarly, the Hubble constant contradiction suggests current cosmological models misunderstand the universe's fundamental physics and evolutionary trajectory.

In today's episode of The Atheist Experience, hosts Forrest Valkai and Jim Barrows tackle the dangerous rise of Christian nationalism and its alignment with fascism, explore the limits of biblical morality, and examine the overwhelming evidence for evolution and geology.Lucy Spina in TX, ACA chair, details the Rainbow Rights Roadshow drive with Equality Texas, aiding LGBTQ+ resource deserts. Hosts stress "no strings attached" secular community support needed against current political threats. Is this grassroots outreach vital?G-Man (nudibranchs jumping sea slugs) argues atheists lack objective morality, asserting God is the source of all good. Hosts challenge this as Divine Command Theory, making God the subjective arbiter. They critique God's immorality, citing the Flood and slavery. Does God's omnipotence and omniscience make him culpable for all sin?Ujay in SD, a deconstructing agnostic, asks for a scientific explanation of evolution and dating methods. Forrest refutes the creationist claim that evolution begets racism, explaining it is Social Darwinism. He details radioisotope half-lives and Hubble's constant for dating the Earth and Universe. Can overwhelming evidence cure religious skepticism?Hannah argues research on morphogenesis (Michael Levin) suggests evidence against materialism, supporting a platonic space of information. The hosts warn against using this gap as evidence for the supernatural. They challenge the assertion as an Argument From Ignorance, noting that complexity does not equal magic. Is Platonism a justifiable conclusion from current unknowns?Thank you all so much for tuning in.

In this episode of Crazy Wisdom, Stewart Alsop talks with Aaron Lowry about the shifting landscape of attention, technology, and meaning—moving through themes like treasure-hunt metaphors for human cognition, relevance realization, the evolution of observational tools, decentralization, blockchain architectures such as Cardano, sovereignty in computation, the tension between scarcity and abundance, bioelectric patterning inspired by Michael Levin's research, and the broader cultural and theological currents shaping how we interpret reality. You can follow Aaron's work and ongoing reflections on X at aaron_lowry.Check out this GPT we trained on the conversationTimestamps00:00:00 Stewart and Aaron open with the treasure-hunt metaphor, salience landscapes, and how curiosity shapes perception. 00:05:00 They explore shifting observational tools, Hubble vs James Webb, and how data reframes what we think is real. 00:10:00 The conversation moves to relevance realization, missing “Easter eggs,” and the posture of openness. 00:15:00 Stewart reflects on AI, productivity, and feeling pulled deeper into computers instead of freed from them. 00:20:00 Aaron connects this to monetary policy, scarcity, and technological pressure. 00:25:00 They examine voice interfaces, edge computing, and trust vs convenience. 00:30:00 Stewart shares experiments with Raspberry Pi, self-hosting, and escaping SaaS dependence. 00:35:00 They discuss open-source, China's strategy, and the economics of free models. 00:40:00 Aaron describes building hardware–software systems and sensor-driven projects. 00:45:00 They turn to blockchain, UTXO vs account-based, node sovereignty, and Cardano. 00:50:00 Discussion of decentralized governance, incentives, and transparency. 00:55:00 Geopolitics enters: BRICS, dollar reserve, private credit, and institutional fragility. 01:00:00 They reflect on the meaning crisis, gnosticism, reductionism, and shattered cohesion. 01:05:00 Michael Levin, bioelectric patterning, and vertical causation open new biological and theological frames. 01:10:00 They explore consciousness as fundamental, Stephen Wolfram, and the limits of engineered solutions. 01:15:00 Closing thoughts on good-faith orientation, societal transformation, and the pull toward wilderness.Key InsightsCuriosity restructures perception. Aaron frames reality as something we navigate more like a treasure hunt than a fixed map. Our “salience landscape” determines what we notice, and curiosity—not rigid frameworks—keeps us open to signals we would otherwise miss. This openness becomes a kind of existential skill, especially in a world where data rarely aligns cleanly with our expectations.Our tools reshape our worldview. Each technological leap—from Hubble to James Webb—doesn't just increase resolution; it changes what we believe is possible. Old models fail to integrate new observations, revealing how deeply our understanding depends on the precision and scope of our instruments.Technology increases pressure rather than reducing it. Even as AI boosts productivity, Stewart notices it pulling him deeper into computers. Aaron argues this is systemic: productivity gains don't free us; they raise expectations, driven by monetary policy and a scarcity-based economic frame.Digital sovereignty is becoming essential. The conversation highlights the tension between convenience and vulnerability. Cloud-based AI creates exposure vectors into personal life, while running local hardware—Raspberry Pis, custom Linux systems—restores autonomy but requires effort and skill.Blockchain architecture determines decentralization. Aaron emphasizes the distinction between UTXO and account-based systems, arguing that UTXO architectures (Bitcoin, Cardano) support verifiable edge participation, while account-based chains accumulate unwieldy state and centralize validation over time.Institutional trust is eroding globally. From BRICS currency moves to private credit schemes, both note how geopolitical maneuvers signal institutional fragility. The “few men in a room” dynamic persists, but now under greater stress, driving more people toward decentralization and self-reliance.Biology may operate on deeper principles than genes. Michael Levin's work on bioelectric patterning opens the door to “vertical causation”—higher-level goals shaping lower-level processes. This challenges reductionism and hints at a worldview where consciousness, meaning, and biological organization may be intertwined in ways neither materialism nor traditional theology fully capture.

Ces cinq dernières années ont été marquées par une augmentation sans précédent du nombre de satellites en orbite autour de la Terre. On commence à peine à en comprendre les répercussions, à l'heure où les débris en orbite sont déjà en tel nombre qu'un micro-impact a récemment empêché le dernier équipage chinois de rentrer sur Terre avec la capsule prévue. Une chose est sûre : le ciel nocturne est en pleine mutation, et les astronomes sont aux premières loges pour en être témoins. Vu du sol, cette flambée satellitaire se manifeste par des traînées lumineuses sur les images astronomiques des grands télescopes, dues à la réflexion de la lumière solaire par les satellites lors de leur déplacement dans le ciel. Mais il n'y a pas que les télescopes terrestres qui sont impactés. Dans un article venant de paraître dans Nature, une équipe de chercheurs montre que la prolifération des satellites a et aura également un impact très important sur les télescopes en orbite.

Nancy Chris Roman Space Telescope Assembly Complete: NASA has successfully assembled the Nancy Chris Roman Space Telescope, a major milestone that brings us closer to its anticipated launch in May 2027. This powerful telescope, equipped with a 288-megapixel camera, promises to gather data hundreds of times faster than Hubble, potentially unveiling over 100,000 new exoplanets and billions of galaxies.Russian Soyuz Rocket Launch Damage: Following a successful launch to the International Space Station, damage was discovered at the Baikonur Cosmodrome, attributed to vibrations and heat from the launch. Repairs are expected to take around three months, but there's no immediate threat to future crewed missions.Satellite Mega Constellations and Light Pollution: A new forecast reveals that satellite mega constellations could severely impact astronomical observations, with projections showing that 1/3 of Hubble's images may be contaminated with satellite trails by the 2030s. Solutions are being explored to mitigate this growing issue.Geological Differences Between Earth and Venus: Recent research sheds light on the geological differences between Earth and Venus, highlighting that Venus operates under a 'squishy lid' regime, which affects its volcanism and tectonic activity. This new framework helps explain the presence of active volcanoes on the otherwise stagnant planet.James Webb Space Telescope's Stunning New Image: The James Webb Space Telescope captures a breathtaking image of two colliding dwarf galaxies, NGC 4490 and NGC 4485, revealing a bridge of gas and new stars formed from their gravitational interaction, showcasing the dynamic nature of the universe.Rare High-Definition Sunspot Images: Astronomers have captured rare high-definition images of sunspots just before they erupted in a powerful solar flare. These images provide critical insights into the sun's magnetic activity and could improve our ability to predict solar events that impact technology on Earth.For more cosmic updates, visit our website at astronomydaily.io.

The world around us has transformed dramatically—but has philanthropy kept up? For our Finding Brave guest today, John Studzinski, American-British investor and humanitarian and the author of the new book A Talent for Giving: Creating a More Generous Society that Benefits Everyone, this question isn't academic—it's deeply personal. His philanthropic journey began humbly, volunteering at a soup kitchen as a teenager. Today, he's recognized globally for transformative work addressing homelessness through London's Passage Day Centre and championing emerging artists through the Genesis Foundation. In the U.S., he serves on the boards of The J. Paul Getty Trust, St. Patrick's Cathedral, and the Foundation for Art and Preservation in Embassies (FAPE) and is a member of the Council on Foreign Relations. In this inspiring conversation, John shares his views on how the true meaning of philanthropy has been lost and how it needs to transform to inspire the next generation to make a more meaningful impact. John tells us about his book and how it has helped inspire individuals to spend the gift of time serving the common good. From the power and importance of human connection to the essential need for empathy, John shares the critical lessons he hopes readers will take from his book. We discuss why giving is not very beneficial unless we understand how, at the same time, to receive. John walks us through how he manages his time in order to be of service to his communities the way he does. John goes on to explain what he believes would happen to humanity if people stopped giving and caring about the community. And he teaches us that so much of our dignity is dependent on what we've given instead of what we've spent or kept. If you have the desire to contribute in new ways and give of your talents and abilities to support the common good, this conversation will inspire you to action. Every person on this planet has authority that can be used for the common good, and leveraging those strengths and talents for the benefit of our communities is not only rewarding but deeply instrumental and meaningful.   Key Highlights From This Episode:  A bit about John's book, A Talent for Giving, and how it's a call to action to serve the common good with your talents. [04:48] How John's faith inspires him to give to the community, and why he always tries to put himself in another person's shoes. [12:47] John discusses how he stewards his time and manages to do everything that he does throughout the day. [16:27] Why empathy is a critical piece in giving, how John wants everyone to read his book, and the most important thing to learn from it. [18:23] The concept of shame, setting boundaries around giving, and how giving is only beneficial if you can receive. [24:30] What would happen in the world if everybody stopped caring about the common good and giving back. [28:55] John tells us about his process of dictating his book and which chapter surprised him the most. [33:30] The first place listeners can start if they want to give back to their community today.

L'univers tel que nous le connaissons repose sur des lois physiques d'une précision stupéfiante. De l'équilibre fragile entre matière et antimatière à la formation des étoiles, en passant par l'existence même des galaxies, chaque étape semble conditionnée par des paramètres qui, s'ils avaient été légèrement différents, auraient rendu notre présence impossible. Faut-il y voir une nécessité cosmique ou le fruit d'un improbable hasard ?Dans cette exploration, nous parcourons les mystères les plus profonds du cosmos : matière noire, énergie noire, trous noirs, champs gravitationnels extrêmes, mais aussi la naissance des galaxies, la mort des étoiles massives, et les signaux insaisissables des pulsars et magnétars. À travers les observations des télescopes les plus puissants — de Hubble à James Webb — nous interrogeons la structure même de l'univers, son origine, son évolution et ce qu'il nous révèle sur notre place en son sein.Mais au-delà des phénomènes spectaculaires et des découvertes technologiques, une question demeure : l'univers a-t-il une intention, une direction… ou n'est-il qu'un enchaînement aveugle de causes et d'effets ? En suivant le fil des connaissances actuelles, cette vidéo propose une réflexion ouverte, à la frontière entre science, philosophie et vertige cosmique.

Ireland has no shortage of stately manors, but as Irish Stew hosts Martin Nutty and John Lee learned, no other historic property has a legacy like Co. Offaly's Birr Castle Demesne, which for generations has been an incubator of breakthroughs in engineering and science.With local historian and educator Brian Kennedy as their guide, the podcasters share the story of the Victorian-era, steampunk-style construction of timber, iron, and stonework that was the world's largest telescope from 1845 to 1917. Built by William Parsons, the 3rd Earl of Rosse, “The Leviathan of Parsonstown” as it became known is a 20-foot-tall engineering marvel that enabled the Earl to map light-years distant nebulae with stunning accuracy that rivals modern Hubble telescope images.Brian points out that the Parsons family's 400-year legacy includes what's thought to be one of the world's earliest surviving suspension bridges on the grounds, Charles Parsons' invention of the steam turbine, and the work of photography pioneer Mary Wilmer Field, the 3rd Countess of Rosse.Her 1850s glass plate photographs are preserved in Ireland's Historic Science Centre at Birr, which not only tells the Birr science story in historical artifacts and interactive displays, but that of Ireland as well.And Birr is still writing that science story today as it hosts the Irish station of the Europe-wide LOFAR radio telescope network, which in 2018 observed for the first time a billion-year-old red-dwarf, flare star.Add botany and horticulture to the science mix with multi-generational botanical treasures on display across the expansive grounds including 17th-century box hedges (among the world's tallest), specimens from China and South America, and Victorian glasshouses under restoration.“There's something in bloom every day of the year, throughout the whole year of plants from right throughout the world.” Brian says.The conversation wraps with a discussion of the town's transformation from "Parsonstown" back to its original Irish name, its connection to St. Brendan's monastery, the charming town's rich Georgian heritage, and things to see and do “off the beaten craic” in Birr's environs.But for Brian, it all starts with the Birr Castle Demesne, “Come early in the morning because one day is just not enough to take in all that the castle has to offer,” he advises.Next week Irish Stew makes one more stop in Co. Offaly at the River Shannon town of Banagher where John and Martin record their first (but not their last) episode in a church!LinksBirr Castle DemesneWebsiteFacebookInstagramLinkedInXYouTubeTikTokHidden Heartlands Travel ResourcesIreland.comDiscover Ireland's Hidden HeartlandsIrish Stew LinksWebsiteEpisode Page: Brian KennedyInstagramLinkedInXFacebookEpisode Details: Season 7, Episode 35; Total Episode Count: 138

Trigger warning, this episode includes a discussion around a sensitive topic that you might find distressing. Listener discretion is very much encouraged.Criticism of the Catholic church, the concept of existence, and whether infinity is real. They are the three big topics for this episode of The People's Countryside Environmental Debate Podcast, the place where you the listener send in questions for co-hosts Stuart ‘The Wildman' Mabbutt and William Mankelow to discuss, dissect, deliberate, sometimes dispute, but very rarely debate, even though that word is in the podcast's title! The first question for this episode comes from Ryszard in Bydgoszcz, Poland - ”If everyone in the world suddenly forgot you existed, did you ever truly exist?”William notes that countless people have lived and died, and that thousands more are dying at this very moment. Many of them pass without anyone knowing or remembering them.Stuart considers whether a person truly exists if everyone forgets them. He notes that actions and thoughts create ripples that persist regardless of memory. Reflecting on identity, he suggests “you” may be an illusion, with the soul merely electrical brain activity, meaning existence could be just a consequence of the bodily functions. He concludes the question remains fundamentally uncertain.William's action: He reflects on mortality by considering two types of death: the physical death of oneself, and the death of the last person who remembers you. He encourages using this perspective to guide actions in life, aiming to leave a positive influence and be remembered meaningfully. Through the podcast, he and Stuart model this by addressing big issues and challenging listeners to think deeply.Stuart's action: whether being unacknowledged or forgotten diminishes a person's impact, and what the nature of “you” truly is. He struggles with the idea of existence tied to memory and suggests it may be possible to be remembered without truly existing. His focus is on examining the concept of self.The second question for this episode comes from Zbigniew in Chorzów, Poland - ”Is infinity real, or is it a mental construct?” William considers the limits of human knowledge about the universe. He notes that the universe's accelerating expansion and the finite speed of light prevent us from fully knowing its size. Despite observing distant regions with telescopes like Hubble and James Webb, much remains beyond our reach.  We never really know if infinity is real. This could all be a simulation. Stuart examines the concept of infinity, suggesting it may or may not be real. He emphasizes that what is certain is that our understanding of it is a human mental construct, shaped by our interpretation of what infinity might or might not be.What do you make of this discussion?

HT2456 - The Most Memorable Photographs of our Age Time has a way of filtering out the unimportant. Think back 500 years ago. We don't remember local politics, but we do remember the great art from that era. What will people, 500 years from now, look back at our era and find most remarkable? I'll guarantee you it won't be your work or my work, nor even the photographs of the masters like Ansel Adams or Edward Weston. No, they will look back at the images the astronauts captured while on the moon, the Voyager, Cassini, and Juno expeditions to the distant planets, the Hubble and Webb telescope images of distant galaxies.

Una de las mayores sorpresas en el campo de la Cosmología fue descubrir que el universo se estaba expandiendo y que la velocidad de expansión es mucho mayor cuanto más lejos estén las galaxias unas de otras. Esa velocidad se mide mediante la constante de Hubble. Pero hay un problema: Su valor no coincide según el método empleado, lo que se conoce como "Tensión de Hubble". Y esa constante es la que se emplea, entre otras cosas, para determinar la edad del universo. Un proyecto internacional se encargará de solucionar esa discrepancia en los valores. Si el problema estuviera en el modelo cosmológico estaríamos ante uno de los descubrimientos más significativos de este siglo. Hemos hablado con Licia Verde, investigadora ICREA del Instituto de Ciencias del Cosmos de la Universidad de Barcelona y coordinadora de RedH0T. -Con Fernando de Castro hemos comentado el proyecto NextBrain, un atlas del cerebro desarrollado por un equipo internacional con participación española, que pone a disposición de los médicos mapas de zonas concretas de este órgano, con posibles aplicaciones para el diagnóstico de enfermedades o de los efectos de un tratamiento. Bernardo Herradón nos ha hablado de las aplicaciones del flúor en medicina, del famoso teflón y de la mala prensa de este elemento químico por su papel en el agujero en la capa de ozono. María González Dionis nos ha contado un estudio sobre la evolución de los perros. Estos animales ya mostraban una gran diversidad hace 11.000 años. Hemos informado de la concesión de la Medalla a la Excelencia Científica 2025 al físico Juan Ignacio Cirac, director del Instituto Max Planck de Óptica Cuántica en Garching (Alemania) y profesor honorario de la Universidad Técnica de Munich.

Hoy nos fuimos a la esencia: cómo de verdad “vemos” el universo. Hablamos de por qué las fotos virales de la NASA usan falsos colores (y por qué eso es MÁS impresionante), qué es la luz invisible que nuestros ojos no detectan, el cometa interestelar que nos visita “de pasada”, la foto Deep Field del Hubble que cambió la perspectiva humana, y por qué el espacio se ve negro.También aterrizamos temas calientes: ¿se puede vivir en Marte?, el choque Vía Láctea–Andrómeda, ciencia vs. religión (cómo convivir sin cancelar la curiosidad), Frankenstein visto desde la física y qué hay de real en Stranger Things/Interstellar (agujeros de gusano, relatividad del tiempo).Si te gusta entender el mundo sin complicarte, este episodio es para ti.

This finding contradicts previous theories suggesting that the expansion was accelerating due to dark energy. We delve into the implications of this research, which indicates that dark energy may be evolving more rapidly than previously understood, potentially marking a paradigm shift in cosmology. The episode discusses various scenarios for the universe's future, including the Big Crunch, Steady State theory, Big Freeze, and Big Rip, and how these new observations could reshape our understanding of cosmic fate.First Glimpse of the Sun's Polar Magnetic FieldAstronomers have captured their first detailed view of the Sun's polar magnetic field in motion, revealing unexpected rapid movements. The Solar Orbiter spacecraft has provided insights into the Sun's magnetic activity, which follows an 11-year cycle. This segment highlights the significance of the findings, which enhance our understanding of solar dynamics and the implications for space weather.Current Surge in Space Weather EventsAs the Sun reaches solar maximum, astronomers are observing increased solar storm activity, including multiple X-class and M-class solar flares. This segment discusses the effects of coronal mass ejections on Earth, including spectacular auroras and potential disruptions to technology and power grids.

Edwin Hubble gets the credit for discovering that the universe is expanding. But that finding was made possible by work done by Vesto Slipher. He was the first to measure the motions of distant galaxies – the key to Hubble’s discovery. Slipher was born 150 years ago today, in Mulberry, Indiana. He worked on the family farm, and developed an interest in astronomy. A college professor helped him get a job as an assistant at Lowell Observatory in Arizona, where he worked for the next five decades. Slipher studied what were called “spiral nebulae.” It wasn’t certain whether these pinwheels were motes of matter in the Milky Way, or “island universes” of stars outside the Milky Way. Slipher used a technique that splits an object’s light into its individual wavelengths. The object’s motion shifts those wavelengths. Objects that are moving away from us are shifted to longer, redder wavelengths. Slipher found that most of the spirals were moving away from us in a hurry. He suggested the objects were far outside the Milky Way. But he couldn’t prove it because he had no way to measure the distances. Hubble did measure the distances, proving that the spirals are separate galaxies. He then combined Slipher’s observations with his own to show that the farther a galaxy, the faster it was moving. Later, astronomers concluded that the universe is expanding – a finding made possible in large part by Vesto Slipher. Script by Damond Benningfield

Blue Origin's Launch Scrubbed: Blue Origin faced a major setback as their second New Glenn rocket launch, carrying NASA's Escapade spacecraft to Mars, was scrubbed due to bad weather, minor equipment issues, and an unexpected cruise ship entering the restricted flight path. The new launch date is set for November 12, with high hopes for a successful mission.Discovery of TOI2267: Astronomers have confirmed a groundbreaking exoplanet system, TOI2267, located 72 light years away in a binary star system. This marks the first time planets have been found transiting both stars, challenging existing models of planet formation and suggesting that rocky planets might be more common in such systems.Innovative Space Food: The European Space Agency is testing a new powdered protein called solane, produced from microbes and astronaut urine, to create a sustainable food source for long-duration space missions. This innovative approach aims to recycle waste into nourishment, ensuring self-sufficiency on future explorations.First Detailed Image of a Star: Astronomers have captured the first detailed image of an individual star outside the Milky Way, a red supergiant named whog64 in the Large Magellanic Cloud. The star's unusual dust cocoon challenges existing models of stellar evolution and raises new questions about massive stars' behavior.Weather on Venus: A new study has modeled the weather on Venus, revealing slow winds that can lift dust due to the planet's dense atmosphere. This finding has significant implications for future landers, as dust storms could pose a threat to missions like NASA's Da Vinci.For more cosmic updates, visit our website at astronomydaily.io.

The Hubble tension problem is breaking cosmology. Cosmology is in crisis. Scientists have argued for decades about how and why the universe is expanding. Now, after careful measurements using multiple methods, the main two don't add up. What do we do when our measurements of the universe don't match up with our models? Are all of our theories wrong?▀▀▀▀▀▀If you love learning about science as much as I do, head to http://brilliant.org/astrum to start for free.

We look at this new and interesting book by Jim Baggott. See more about Discordance The Troubled History of the Hubble Constant here. Discordance The Troubled History of the Hubble Constant, reviewed We are living in interesting times for studies about our universe. It looks like it is still expanding, fair enough if the big bang did it's thing, and exploded out from an incredibly small amount of space and matter. But, as the data increasingly suggests, the rate of the expansion is not only continuing, but also increasing the rate at which it does so. Baggott takes us on an interesting, well informed and clearly explained journey around the important developments and discoveries, especially over the last century or so. At some points the maths and the physics naturally left us behind, but, overall this is an accessible and comprehensible book for the wider reader. Time and time again it seems like our best and deepest thinkers have to conceive theoretical ideas and then often wait decades, often beyond their own lifetimes, before humanity has built sufficient tools to then test them. Often then, such was the brilliance of Einstein and others, their concepts turned out to be right. The clear example of the concept of black holes, long, long before it was ever possible to definitively proof their existence. This has repeatedly been the process, which the Hubble Telescope, Cern and the Higgs boson, and now with the James Watt Telescope, have all helped us to then conclusively prove or disprove concepts. All of this of course a massive riposte to the recent insane cuts in scientific research, and evidence based concepts. It is an exciting time new massive arrays coming online, and the far great capacity of JW and more to scan more of the sky, in higher resolution. Faster methodologies are also emerging to analyse what is being captured too. All of which means that new discoveries are being made near daily too. Baggot helps to communicate an interesting overview of these developments, and captures the enthusiasm that is out there in terms of sharing of ideas and robustly testing previously held ideas. Naturally dark matter and dark energy can still seem slightly questionable, as they are, by their nature, currently impossible, or at least extremely difficult to measure, observe or capture. At the same time, something has to be there to account for the fact that we can see, and measure so little of what must be around us. It does show we still have a long way to go in terms of understanding how the universe works and what is happening around us. Books like this help to communicate why this is important, interesting and well worth studying and investment. Check it out. More about the book Discordance The troubled history of the Hubble constant: a story littered with crises of confidence, astonishing discoveries, and extraordinary personalities, which still continues today. From the award-winning science-writer and author of Quantum Drama. In 1927 Georges Lemaître argued that our universe is expanding, a conclusion rendered more startling by the astronomical data that backed it up, presented two years later by Edwin Hubble. The speed of this expansion is governed by Hubble's constant, and Discordance tells its troubled history. This unpredictable and fascinating story begins with the first tentative steps to measure the distances to nearby stars and galaxies. It traces the extraordinary interplay between cosmological theory and astronomical observation which has given us the standard Big Bang theory. It was not all plain sailing, and the narrative takes us through the discovery of dark matter, the Hubble Wars of the 1970s, the invention of cosmic inflation, and other crucial scientific moments. Further satellite missions were expected to add to the clarity of our measurements. But from about 2009 onward, the results began to diverge and complicate our understanding of this expansion. This is the Hubble tension and perhaps even a cr...

WhoBarry Owens, General Manager of Treetops, MichiganRecorded onJune 13, 2025About TreetopsClick here for a mountain stats overviewOwned by: Treetops Acquisition Company LLCLocated in: Gaylord, MichiganYear founded: 1954Pass affiliations: Indy Pass, Indy+ Pass – 2 daysClosest neighboring ski areas: Otsego (:07), Boyne Mountain (:34), Hanson Hills (:39), Shanty Creek (:51), The Highlands (:58), Nub's Nob (1:00)Base elevation: 1,110 feetSummit elevation: 1,333 feetVertical drop: 223 feetSkiable acres: 80Average annual snowfall: 140 inchesTrail count: 25 (30% beginner, 40% intermediate, 30% advanced)Lift count: 5 (3 triples, 2 carpets – view Lift Blog's inventory of Treetops' lift fleet)Why I interviewed himThe first 10 ski areas I ever skied, in order, were:* Mott Mountain, Michigan* Apple Mountain, Michigan* Snow Snake, Michigan* Caberfae, Michigan* Crystal Mountain, Michigan* Nub's Nob, Michigan* Skyline, Michigan* Treetops, Michigan* Sugar Loaf, Michigan* Shanty Creek – Schuss Mountain, MichiganAnd here are the first 10 ski areas I ever skied that are still open, with anything that didn't make it crossed out:* Mott Mountain, Michigan* Apple Mountain, Michigan* Snow Snake, Michigan* Caberfae, Michigan* Crystal Mountain, Michigan* Nub's Nob, Michigan* Skyline, Michigan* Treetops, Michigan* Sugar Loaf, Michigan* Shanty Creek – Schuss Mountain, Michigan* Shanty Creek – Summit, Michigan* Boyne Mountain, Michigan* Searchmont, Ontario* Nebraski, Nebraska* Copper Mountain, Colorado* Keystone, ColoradoSix of my first 16. Poof. That's a failure rate of 37.5 percent. I'm no statistician, but I'd categorize that as “not good.”Now, there's some nuance to this list. I skied all of these between 1992 and 1995. Most had faded officially or functionally by 2000, around the time that America's Great Ski Area Die-Off concluded (Summit lasted until around Covid, and could still re-open, resort officials tell me). Their causes of death are varied, some combination, usually, of incompetence, indifference, and failure to adapt. To climate change, yes, but more of the cultural kind of adaptation than the environmental sort.The first dozen ski areas on this list are tightly bunched, geographically, in the upper half of Michigan's Lower Peninsula. They draw from the same general population centers and suffer from the same stunted Midwest verticals. None are naturally or automatically great ski areas. None are or were particularly remote or tricky to access, and most sit alongside or near a major state or federal highway. And they (mostly) all benefit from the same Lake Michigan lake-effect snow machine, the output of which appears to be increasing as the Great Lakes freeze more slowly and less often (cold air flowing over warm water = lake-effect snow).Had you presented this list of a dozen Michigan ski areas to me in 1995 and said, “five of these will drop dead in the next 30 years,” I would not have chosen those five, necessarily, to fail. These weren't ropetow backwaters. All but Apple had chairlifts (and they soon installed one), and most sat close to cities or were attached to a larger resort. Sugar Loaf, in particular, was one of Michigan's better ski areas, with five chairlifts and the largest in-state vertical drop on this list.My guess for most-likely-to-die probably would have been Treetops, especially if you'd told me that then-private Otsego ski area, right next door and with twice its neighbor's skiable acreage, vertical drop, and number of chairlifts, would eventually open to the public. Especially if you'd told me that Boyne Mountain, the monster down the road, would continue to expand its lodging and village, and would add a Treetops-sized cluster of greens to its ferocious ridge of blacks. Especially if you'd told me that Treetops' trail footprint, never substantial, would remain more or less the same size 30 years later. In fact, just about every surviving Michigan ski area on that list - Crystal, Nub's, Caberfae, Shanty Schuss - greatly expanded its terrain footprint. Except Treetops.But here we are, in the future, and I just skied Treetops 10 months ago with my 8-year-old son. It was, in some ways, more or less as I'd left it on my last visit, in 1995: small vert, small trail network, a slightly confusing parking situation, no chairlift restraint bars. A few improvements were obvious: the beginner ropetows had made way for a carpet, the last double chair had been upgraded to a triple, terrain park features dotted the east side, and a dozen or so glades and short steep shots had been hacked from the woods of the legacy trail footprint.That's all nice. But what was not obvious to me was this: why, and how, does Treetops the ski area still exist? Sugar Loaf was a better ski area. Apple Mountain was closer to large population centers. Summit was attached to ski-in-ski-out accommodations and shared a lift ticket with the larger Schuss mountain a couple miles away. Was modern Treetops some sort of money-losing ski area hobby horse for whomever owned the larger resort, which is better known for its five golf courses? Was it just an amenity to keep the second homeowners who mostly lived in Southeast Michigan invested year-round? Had the ski area cemented itself as the kind of high-volume schoolkids training ground that explained the resilience of ski areas in metro Detroit, Minneapolis, and Milwaukee?There is never, or rarely, one easy or obvious explanation for why similar businesses thrive or fail. This is why I resist pinning the numerical decline in America's ski area inventory solely to climate change. We may have fewer ski areas in America than we had in 1995, but we have a lot more good ski areas now than we did 30 years ago (and, as I wrote in March, a lot more overall ski terrain). Yes, Skyline, 40 minutes south of Treetops, failed because it never installed snowmaking, but that is only part of the sentence. Skyline failed because it never installed snowmaking while its competitors aggressively expanded and continually updated their snowmaking systems, raising the floor on the minimal ski experience acceptable to consumers. That takes us back to culture. What do you reckon has changed more over the past 30 to 40 years: America's weather patterns, or its culture? For anyone who remembers ashtrays at McDonald's or who rode in the bed of a pickup truck from Michigan to Illinois or who ran feral and unsupervised outdoors from toddlerhood or who somehow fumbled through this vast world without the internet or a Pet Rectangle or their evil offspring social media, the answer seems obvious. The weather feels a little different. Our culture feels airlifted from another planet. Americans accepted things 30 years ago that would seem outrageous today – like smoking adjacent to a children's play area ornamented with a demented smiling clown. But this applies to skiing as well. My Treetops day in 1995 was memorably horrible, the snow groomed but fossilized, unturnable. A few weeks earlier, I'd skied Skyline on perhaps a three-inch base, grass poking through the trails. Modern skiers, armed with the internet and its Hubble connection to every ski area on the planet, would not accept either set of conditions today. But one of those ski areas adapted and the other did not. That's the “why” of Treetops survival. It was the “how” that I needed Barry Owens to help me understand.What we talked aboutLast winter's ice storm – “it provides great insight into human character when you go through that stuff”; record snowfall (204 inches!) to chase the worst winter ever; the Lake Michigan snowbelt; a golf resort with a ski area attached; building a ski culture when “we didn't have enough people dedicated to ski… and it showed”; competing with nearby ski areas many times Treetops' size “we don't shy away from… who we are and what we are”; what happened when next-door-neighbor Otsego Resort switched from a private to a public model in 2017 – “neither one of us is going to get rich seeing who can get the most $15 lift tickets on a Wednesday”; I attempt to talk about golf and why Michigan is a golf mecca; moving on from something you've spent decades building; Treetops' rough financial period and why Owens initially turned down the GM job; how Owens convinced ownership not to close the ski area; fixing a “can't-do staff” by “doing things that created the freedom to be able to act”; Treetops' strange 2014 bankruptcy and rebuilding from there; “right now we're happy” with the lift fleet; how much it would cost to retrofit Treetops' lifts with restraint bars; timeline for potential ski expansion at Treetops; bargain season passes (as low as $125); and Indy Pass' network power.What I got wrong* I said “Gaylord County,” but the city of Gaylord is in Otsego County.* I said that Boyne Resorts, operator of 11 ski areas, also runs “10 or 11 golf resorts.” The company operates 14 golf courses.* I said that Michigan had a “very good” road network and that there was “not a lot of traffic,” and if you live there, you're reaction is probably, “you're dumb.” What I meant by “very good road network” is this: compared to most ski regions, which have, um, mountains, Michigan's bumplets sit more or less directly alongside the state's straight, flat, almost perfectly gridded highway network. Also, the “not a lot of traffic” thing does not apply to special situations like, say, northbound I-75 on a July Friday evening.* I said that Crystal, Nub's, Caberfae, and Shanty Creek were “close” – while they're not necessarily all close to one another, they are all roughly equidistant for folks coming to them from downstate.* I said that Treetops was “the fifth or sixth place I ever skied at,” but upon further review, it was number eight (which is reflected in the list above).Podcast NotesOn the ice stormAn ice storm hammered Northern Michigan in late March of this year:On the lightning strike on Treetops' golf courseOn the Midwest's terrible 2023-24 ski seasonSkier visits cratered in the Midwest during the 2023-24 ski season, the region's worst on record from a snowfall point of view. Weather - and skier visits - settled back into normal ranges last winter:This is a bit hard to see with any sort of precision, but this 10-year chart gives a nice sense of just how abnormal 2023-24 was for the Midwest:On Michigan's ski areasMichigan is home to 44 active ski areas - more than any state other than New York. Many of them are quite small, operate sporadically, and run only surface lifts, but Treetops is close to a bunch of the better lift-served outfits, including Boyne Mountain, Nub's Nob, and The Highlands (the UP ski areas may as well be in another state). It helps Treetops that so many of the state's ski areas have also joined Indy Pass:On Otsego ResortFor decades - I'm not certain how long, exactly - Otsego Resort, right next door to Treetops and with roughly double the vertical drop and skiable acreage, was private. In 2017, the bump opened to the public, considerably amping up competition. Complicating the matter further, Otsego sits a bit closer to Michigan's Main Street - I-75 - than Treetops.On Snow OperatingOwens mentioned working with “TBL” – he was referring to Terrain Based Learning, Snow Partners' learn-to-ski program. That company also runs the Snow Cloud operating system that Owens refers to at the end.On Treetops' rough period I quoted this Detroit Business News article at length in the interview. It goes deep on Treetops' precarious early 2000s history and the resort's broken employee culture at the time.On people being nice at ski areasYeah I'm super into this:On the hedgehog conceptOwens mentions “the hedgehog concept,” which I wasn't familiar with. It sounded like a business-book thing, and it is, adapted by author Jim Collins for his book Good to Great and described in this way on his website:The Hedgehog Concept is developed in the book Good to Great. A simple, crystalline concept that flows from deep understanding about the intersection of three circles: 1) what you are deeply passionate about, 2) what you can be the best in the world at, and 3) what best drives your economic or resource engine. Transformations from good to great come about by a series of good decisions made consistently with a Hedgehog Concept, supremely well executed, accumulating one upon another, over a long period of time.More:On safety-bar requirements in New York and New EnglandThis is kind of funny…That's my 8-year-old son, who's skied in a dozen states, taking his first ride on a lift with no safety bar, at Treetops last December. Why such machines still exist in 2025, I have no idea - this lift rises about 30 feet off the ground. In the East, all chairlifts are equipped with bars, and state law mandates their use in New York, Massachusetts, and Vermont (and perhaps elsewhere). I don't advocate for rider mandates, but I do think all chairlifts ought to have bars available for those who want them. Owens and I discuss the resort's plans to retrofit Treetops' three chairlifts - CTEC machines installed between 1984 and 1995 - with bars. The cost would be roughly $250,000. That's a significant number, but probably a lot less than the figure if, say, someone has a heart attack or seizure on the lift, falls off, then sues the resort. Besides, as Owens points out, chairlifts must be equipped with restraint bars for summer use, which would open new revenue streams. Why are bars required for summer activities, but not winter? It's a strange anachronism, unique among the ski world to America.On “Joe from SMI”I mentioned “Joe from SMI” offhand. I was referring to SMI Snowmakers President Joe VanderKelen, who appeared on the podcast back in 2022:On potential expansion Owens discusses a potential expansion looker's left of Chair 1, which would restore lost terrain and built upon that. This 1988 trailmap shows a couple of the trails that Treetops eliminated to make way for its current top-to-bottom access road (trails 1 through 4):The Storm explores the world of lift-served skiing year-round.

My Star Trek Story: The True Story Behind the Star Trek: The Next Generation Episode "True Q", and also Remember The Rollerdogs.

How does a star form? How does the universe form? And how can we use every bit of astronomical data to answer those questions? To find out, Dr. Charles Liu and co-host Allen Liu welcome astrostatistician Sabrina Berger, all the way from Melbourne, Australia, where she's currently pursuing her PhD. As always, though, we start off with the day's joyfully cool cosmic thing, the new radioastronomy photographs of Callisto, one of the moons of Jupiter, taken by ALMA. Sabrina talks about her own low-frequency radio astronomy research looking for hydrogen in the very early reionization period of the universe when the first galaxies were forming. (Be warned: we dive into the difficulties ionization poses for trying to discern these early processes, including a side trip into quantum mechanics, the hyperfine transition of neutral hydrogen at 21cm depicted on the plaque attached to the Pioneer spacecraft, and even the Cosmic Background Radiation.) You'll also hear how Sabrina is innovatively using GPS satellites to help calibrate large radioastronomy telescope arrays. For our first student question, Derek asks, “I heard that black holes can form right after the Big Bang, before stars do. How is that possible?” Sabrina describes these primordial black holes, and, although none have been confirmed yet, that there have been a number of papers published recently on the subject. In fact, one paper suggesting that the as-yet-undiscovered “Planet 9” could even be one of these primordial black holes. And then, finally, we get to the subject of astrostatistics, Sabrina's area of expertise. She explains that it allows you to harness every piece of information that you're observing in astronomy and to answer questions like “How does a star form?” or “How does the universe form?” You'll hear about huge data sets, the use of artificial intelligence, field level inferences… and the MCMC, or the Markov chain Monte Carlo used in statistics. (If you don't know what that is, you're not alone, and our own resident mathematician Allen helps Sabrina untangle the complexity with a cotton ball analogy that blew Chuck and Sabrina's collective minds!) For our next student question, Wally asks, “Why is redshift one like nine billion years ago, bur redshift two only two billion years before that, and redshift three only one billion years before that?” As Chuck says, “that's a little complicated,” just before he, Allen and Sabrina proceed to explain how we measure universal expansion, the passage of time, and the “stretching” of light. Our next conversation is one of the most controversial we've ever had and revolves around who Sabrina thinks makes the best espresso, Australia, Italy or a “Third Wave Coffee Shop” like we have here in the US. You'll hear about why there's an ISSpresso machine on the ISS – and how the Italian Space Agency invented a way to make an espresso in zero-g! Plus, you'll hear a little about the work-life balance in Australia and how wonderful astronomy down under is. (Check out our Patreon for the story behind the Australian Aboriginal "Emu-in-the-sky" constellation.)

Desde Galileo hasta Einstein y Hubble, los científicos han lidiado durante mucho tiempo con la forma y la escala del Universo. A pesar de los avances, este enigma cósmico sigue sin resolverse. Más allá de lo visible Algunas de las maravillas más violentas de la naturaleza se ocultan a plena vista y tienen el poder de destrozar el espacio y el tiempo. Es el caso de los agujeros negros.

HEADLINE: Solving the Mystery of Bright Red Dots in the Early Universe GUEST NAME: Dr. Joel LejaSUMMARY: John Batchelor interviews Dr. Joel Leja about "little red dots"—extremely bright, mysteriously common objects discovered in the early universe by the James Webb Space Telescope. These enigmatic red dots appear to be early supermassive black holes, possibly tens of millions of solar masses, revealed by intensely hot gas swirling at tremendous velocities around them. Their unexpected abundance and size so close to the universe's beginning poses a fundamental challenge to current theories of cosmic evolution and black hole formation. The discovery suggests that supermassive black holes formed much earlier and more rapidly than previously thought possible, requiring astronomers to reconsider models of how the first galaxies and their central black holes emerged from the primordial darkness. Dr. Leja explains that while the JWST data strongly indicates these are black holes based on spectroscopic signatures, the mechanism that allowed such massive objects to form so quickly after the Big Bang remains one of astronomy's most perplexing new mysteries. The research highlights how advanced telescopes continue to overturn established assumptions about the early universe's structure and evolution. HUBBLE

The closest giant galaxy to the Milky Way is Messier 31, the Andromeda Galaxy. It’s two-and-a-half million light-years away. But it’s getting closer – by about 250,000 miles every hour. For more than a decade, in fact, it’s looked like the two galaxies were on a collision course. But a recent study says there’s only a 50-50 chance of a collision and merger. And if it does happen, it’ll take place billions of years later than previous estimates. The new study used years of observations by two space telescopes – Hubble and Gaia. Researchers plugged those observations into simulations that also considered the gravitational effects of two smaller galaxies. The results indicated that one of them tends to push Andromeda and the Milky Way together, while the other tends to pull them apart. The researchers ran a hundred thousand simulations. In half of them, Andromeda and the Milky Way flew past each other and went their own ways. In the other half, they eventually spiraled together and merged – but not for at least 10 billion years – twice as long as earlier estimates. The simulations aren’t the final word – there are just too many uncertainties. But for now, it seems likely that the two giants will stay apart for a long, long time. M31 is in the northeast at nightfall. Under dark skies, it’s visible as a hazy patch of light. Binoculars make it easier to pick out. Script by Damond Benningfield

Pack your cosmic suitcase. This week on Planetary Radio, host Sarah Al-Ahmed is joined by Mark McCaughrean, astronomer, science communicator, and former Senior Advisor for Science & Exploration at the European Space Agency, to talk about his new book, “111 Places in Space That You Must Not Miss.” Part of the popular “111 Places” travel series, the book transforms the guidebook format into a tour across the Solar System and beyond, from Apollo landing sites on the Moon to Europa’s hidden oceans, and even the afterglow of the Big Bang. Mark shares highlights from the book, stories from his career on missions like Hubble, Rosetta, and the James Webb Space Telescope, and reflections on how science and imagination come together to inspire exploration. And in this week’s What’s Up, Planetary Society Chief Scientist Bruce Betts joins Sarah to talk about his brand-new children’s books, “The Size of Space” and “Are We Alone?,” part of our growing series with Lerner Publishing Group.

Get my My new book, Focus Like a Nobel Prize Winner -- https://a.co/d/hi50U9U It's just 99¢ on Kindle for launch week ONLY. It's the perfect companion to this conversation—lessons in thinking clearly, staying curious, and pushing past conventional wisdom from my conversations with 22 Nobel Prize winners! Brian Keating sits down with Harvard astrophysicist Avi Loeb and renowned skeptic Michael Shermer to dissect the latest enigma sweeping through our solar system—3I/ATLAS. • What makes 3I/ATLAS extraordinary? • It's the third confirmed interstellar object to visit our solar system—after ʻOumuamua and Borisov—racing through space at hyperbolic speeds and exhibiting an orbit intriguingly aligned with our ecliptic plane • Observations by Hubble and James Webb reveal a coma dominated by carbon dioxide, with traces of water, carbon monoxide, nickel, and cyanide—an unusual chemical signature even among comets. • Avi Loeb's provocative hypothesis: He and collaborators propose that 3I/ATLAS might not be natural at all—but potentially a piece of alien technology, given its improbable trajectory, ecliptic alignment, and close approach to Mars and other planets—arguably orchestrated rather than accidental. • Michael Shermer pushes back: A constructive skeptic's view on whether the evidence truly supports Loeb's scenario, grounding the discussion with a critical evaluation of observational data versus speculative inference. Don't miss this rare convergence of cutting-edge astrophysics and disciplined skepticism—because how we interpret 3I/ATLAS could redefine our understanding of interstellar visitors.
