Astronomy Daily S05E152 — “Reading the Heat” · Tuesday 28 July 2026. Hosts Anna & Avery. NASA's Juno spacecraft has taken the first-ever temperature reading beneath the surface of Io, Jupiter's volcanic moon — and the technique behind it could reshape how we study icy ocean moons and even volcanoes on Earth. We also look at why JWST's “Little Red Dots” might be globular clusters being born, the first SETI search built from archived ALMA data (and its six-million-star surprise), and a live burst of space weather feeding into a meteor-filled — if Moon-washed — skywatch. In this episode ●        Juno reads Io's subsurface temperature for the first time — >20°C rise within a few metres, heat flow up to ~30× Earth's average, and a remarkably smooth, low-density surface. ●        Why the method matters: a multi-depth microwave thermometer that works from orbit — promising for Europa, Enceladus, and terrestrial volcanology. ●        JWST's “Little Red Dots” may be globular clusters in formation, powered by a short-lived supermassive star — linking two long-standing mysteries. ●        The first SETI survey of archived ALMA data opens the millimetre band — and reveals “stellar bycatch” of 6.1 million background stars. ●        Live space weather: an M3.2 flare from region AR4494 and a glancing CME, with G1–G2 storms and possible aurorae, north and south. ●        Skywatch: meteor week under the full Buck Moon (29 July), the Alpha Capricornid fireball tip, evening Venus, pre-dawn Saturn/Mars/Mercury — and Jupiter vanishing behind the Sun.

Some of the most exciting discoveries in the universe are often in some of the hardest places to reach.

Algumas das luas de Júpiter e Saturno têm sido objetos de interesse da astrobiologia há tempos. Novas missões estão a caminho para explorar alguns desses satélites e procurar  condições de habitabilidade que podem estar em grandes oceanos debaixo da superfície. Aqui na Terra, o estudo de organismos que vivem e se reproduzem em ambientes considerados extremos, os extremófilos, pode ajudar a entender como a vida pode se adaptar a condições de temperatura extremamente baixa, entre outros estressores. Para tratar do tema, o repórter Danilo Albergaria conversou com as pesquisadoras Amanda Bendia e Maria Eduarda Nascimento, ambas do Instituto Oceanográfico da USP, Rosaly Lopes, da NASA e Douglas Galante, do Instituto de Geociências, também da USP. Este é o terceiro episódio de uma série produzida pelo Danilo, com apoio do Programa Mídia Ciência, da FAPESP. _________________ Roteiro Danilo: Nos dois primeiros episódios do podcast Oxigênio dedicados à astrobiologia, falamos da busca por vida em exoplanetas e em Marte. Desde os anos 60, Marte foi o objeto que mais capturou as atenções dos cientistas interessados em entender se a vida pode ter surgido e  persistido em outros lugares do sistema solar. Mas esse panorama tem mudado nas últimas décadas. Desde as missões Galileo e Cassini, algumas das luas que orbitam Júpiter e Saturno entraram no rol de mundos com potencial de oferecer condições habitáveis à vida como a conhecemos. Novas missões espaciais estão a caminho ou em fase final de preparação para explorar algumas das luas dos gigantes gasosos. Entre os seus objetivos está entender melhor as potenciais condições de habitabilidade nos grandes oceanos debaixo da superfície dessas luas – ou seja, os cientistas querem saber se esses lugares oferecem condições suficientes para que seres vivos sobrevivam. Nesse episódio, eu entrevistei quatro cientistas que trabalham direta ou indiretamente com isso. Com eles, vamos explorar o que sabemos – e o que ainda não sabemos – sobre as luas geladas do sistema solar. Será que pode existir vida nesses lugares? É isso o que muita gente que pesquisa astrobiologia quer saber. [Vinheta] Danilo: Algumas das missões mais importantes da exploração espacial do presente e do futuro próximo estão destinadas às luas de Júpiter e Saturno. Vamos falar primeiro das que vão explorar a vizinhança de Júpiter.  A sonda JUICE, acrônimo para “explorador das luas geladas de Júpiter” em inglês, foi lançada pela ESA (a agência espacial europeia) em 2023 para explorar Ganimedes, Calisto e Europa, três das quatro luas de Júpiter chamadas de galileanas. O quarteto foi observado pela primeira vez há mais de 400 anos por Galileu Galilei. A não ser pela nossa própria Lua, nenhuma lua do sistema solar é visível a olho nu. Galileu foi o primeiro a observar as luas de Júpiter usando um telescópio, invenção recente que tinha sido aprimorada por ele. As luas galileanas de Júpiter são relativamente grandes. Embora ainda sejam objetos bem menores do que a Terra, Ganimedes e Calisto são um pouco maiores do que a nossa Lua, enquanto a  Europa é um pouco menor. A quarta lua, a Io – um verdadeiro inferno vulcânico, e que não estava no radar de estudos da missão de 2023 como as demais, é praticamente do mesmo tamanho da nossa Lua.  A JUICE está a caminho do sistema joviano, ou seja, Júpiter e suas luas, mas ainda se encontra na vizinhança da Terra. Ela deve se aproximar de novo de nós para pegar embalo com a gravidade do nosso planeta, que vai estilingar a sonda para o sistema solar externo. A JUICE deve chegar aos arredores de Júpiter em julho de 2031. Outra sonda, a Europa Clipper, da NASA, foi lançada em outubro de 2024 para investigar, como o nome sugere, a lua Europa, a mais interessante das luas de Júpiter. A estilingada da Europa Clipper, ao passar perto da Terra, vai acontecer um pouco depois da passagem da JUICE – vai ser em dezembro de 2026, mas a Clipper deve chegar antes à vizinhança de Júpiter, em abril de 2030. A Clipper vai orbitar Júpiter e passar bem pertinho da superfície de Europa umas 50 vezes. Além das duas missões ocidentais, a China está planejando lançar uma sonda em 2029 para chegar a Júpiter em 2035 e explorar as luas Calisto e Ganimedes. Por que tanto interesse nessas grandes luas de Júpiter? Como eu já indiquei no começo do episódio, existem muitos indícios e evidências indiretas de que Europa, Calisto e Ganimedes têm enormes oceanos debaixo de uma espessa superfície gelada. A estimativa é de que cada uma dessas três luas tenha corpos de água líquida maiores do que todos os oceanos terrestres. Conversei sobre isso com o Douglas Galante, professor do Instituto de Geociências da USP e um dos pioneiros da astrobiologia no Brasil – ele é vice-coordenador do AstroLab, da USP, o primeiro laboratório dedicado à pesquisa em astrobiologia no país, fundado em 2011 por Douglas, pelo químico Fabio Rodrigues, atual coordenador do laboratório, e pelo Ivan Paulino-Lima, que hoje é pesquisador na NASA. Douglas: Uma coisa sempre interessante quando a gente pensa nessas luas geladas que eu sempre falo é que a gente adora falar que a Terra é o planeta água, algo que ficou popularizado, e a gente esquece de pensar que nessas luas de Júpiter e Saturno a gente tem mais água do que aqui na Terra. É em cada uma delas. Então a gente é muito presunçoso. Europa, os modelos mostram que ela pode ter um oceano de 100 quilômetros de profundidade. A gente não consegue imaginar o que são 100 quilômetros. O ponto mais profundo aqui na Terra, da Fossa das Marinas, são 11 quilômetros. Imagina 10 vezes mais. Danilo: Ganimedes, a maior lua de todo o sistema solar, deve ter um oceano seis vezes maior do que todos os oceanos da Terra combinados. Mas esses enormes corpos de água líquida não estão na superfície das luas, e sim debaixo de superfícies congeladas que podem chegar a centenas de quilômetros de espessura. Júpiter está cinco vezes mais distante do Sol do que a Terra, e o frio a essa distância do Sol impossibilita a existência de água líquida na superfície das luas. O Douglas chamou a atenção para o fato de que essas luas estendem possível habitabilidade para além da região em que a Terra orbita, mais próxima do Sol e que permite água líquida na superfície. Douglas: Mas o que eu acho super interessante, que eu sempre coloco, é que as luas dão um indicativo de habitabilidade que é maior do que a gente conhecia. Quando a gente olha os conceitos de habitabilidade tradicionais, que definem a zona de habitabilidade estelar, que é a presença de água líquida na superfície, as luas são ambientes crípticos que obtêm energia para manutenção da água líquida a partir da interação gravitacional com seus planetas hospedeiros. Danilo: Ok, mas se a superfície é gelada demais para ter água líquida, como esses oceanos podem existir? A explicação é a seguinte: o decaimento radioativo dos elementos que formam o núcleo das luas gera calor considerável de forma mais ou menos constante, parecido com o que acontece com o núcleo da Terra. Mas isso é só parte da explicação. Entra, então, o chamado “aquecimento de maré”. Conforme a lua se desloca na órbita do planeta gigante, a atração gravitacional do planeta não é uniforme: como a órbita não é circular, mas elíptica (ou “ovalada”), as luas às vezes estão um pouco mais perto e às vezes um pouco mais longe do planeta. Isso produz um efeito de “estica e puxa” que estica e comprime a lua, e isso gera calor entre as suas camadas internas. Também entra aí o fato de que as órbitas de Ganimedes, Io e Europa estão em ressonância, ou seja, enquanto a Io completa uma volta, a Europa completa duas, e a Ganimedes, quatro, o que aumenta a excentricidade de suas órbitas (ou seja, estica um pouco a elipse). Nesse processo, a própria variação na distância entre as luas gera uma interação gravitacional que contribui para o efeito de aquecimento de maré. Além disso, a provável presença de sais nos oceanos faz com que o ponto de congelamento diminua, mantendo a água em estado líquido. A JUICE e a Europa Clipper serão importantes para entender melhor as superfícies das luas e colher dados indiretos que indiquem algumas características desses oceanos, incluindo informações sobre se eles oferecem condições habitáveis para a vida como a conhecemos. Água líquida é uma das condições necessárias. Mas como os cientistas vão fazer para saber o que mais pode haver nesses oceanos?  [Música] Danilo: Para entender como os cientistas vão fazer para saber mais sobre as luas geladas, eu conversei com a Rosaly Lopes, que é diretora de ciências planetárias do JPL, o Laboratório de Propulsão a Jato da NASA. Ela teve atuação importante na missão Galileo, que explorou as luas de Júpiter entre 1995 e 2003.  Rosaly: Eu trabalhei na missão Galileo e a missão Galileo foi que descobriu que a Ganimedes e a Europa tinham oceanos de água líquida debaixo de uma crosta de gelo, principalmente Europa. Aí o pessoal fica muito entusiasmado porque Europa, nós sabemos que tem calor no interior, tem sinais de criovulcanismo, criovulcanismo é o vulcanismo que traz essa água líquida do interior para a superfície. E são três coisas essenciais para existir vida, vida como a nossa: água, energia, como calor, como vulcanismo, e material orgânico. Nós não sabemos muito sobre o material orgânico em Europa. Sabemos mais em Encélado e Titã, por exemplo. Eu também trabalhei na missão Cassini. Mas a missão que está indo agora para a Europa vai estudar justamente os depósitos da superfície para ver se é material orgânico ou não. Danilo: Encélado e Titã são luas de Saturno, e a Cassini foi a missão da NASA que explorou o sistema saturniano entre 2004 e 2017. Vamos falar delas daqui a pouco. Por ora, o que a Rosaly falou sobre possível criovulcanismo (ou vulcanismo gelado) em Europa é importante porque pode ser um dos mecanismos pelos quais parte do oceano do interior poderia ser expelida em enormes plumas de vapor de água e gelo. Não é algo completamente diferente de vulcões expelindo o magma do manto terrestre para a superfície. A Europa Clipper carrega instrumentos capazes de fazer medições que vão ser usadas para distinguir se essas plumas contêm material vindo do oceano profundo ou de pequenos reservatórios mais próximos da superfície. As pistas de criovulcanismo na superfície incluem anomalias de temperatura em determinadas regiões – mais quentes do que o esperado – além da presença de características que lembram fluxos de erupções ou de derretimento de geleiras aqui na Terra. Aliás, junto com a ausência de crateras de impacto de grande porte, isso indica que a superfície de Europa é jovem, devendo ter entre 50 e 100 milhões de anos. Em comparação, a superfície de Marte e da nossa Lua, formadas há bilhões de anos, tem muitas dessas grandes crateras, o que indica que a superfície não se renova. Ao examinar a superfície de Europa com a Clipper, os cientistas vão poder fazer inferências sobre seu interior. Mas a sonda não vai pousar na superfície da lua. Em vez disso, ela vai orbitar Júpiter e fazer 44 rasantes sobre Europa.  Douglas: Na verdade, ela não vai nem orbitar a Lua, ela vai ficar fazendo flybys em volta da Lua, vai fazer rasantes na Lua, e quando ela faz esses rasantes, ela faz uma série de imagens de alta resolução, faz medidas espectroscópicas para medir a composição, mas ela não vai, de fato, acessar diretamente o potencial oceano líquido que existe ali debaixo. E daí todo mundo pergunta, mas porque a gente não simplesmente pousa na superfície da Lua, faz um furo, mede a água e vê o que tem ali e pega um atum europeano, sei lá. Então isso é uma coisa complicada, porque o oceano de Europa tem 100 km de profundidade. A crosta, a gente fala que é uma crosta fina, mas fina, de 10 km de espessura. A gente tem que lembrar que as calotas polares aqui no nosso planeta têm de 4 a 4,5 quilômetros de profundidade.  Danilo: Pesquisadores estão explorando a potencial habitabilidade de oceanos de subsuperfície das luas analisando os seres vivos encontrados em condições muito adversas, extremas. A Amanda Bendia é professora do Instituto Oceanográfico da USP e coordenadora do ExtreMar, o Laboratório de Extremófilos Marinhos do instituto. Extremófilos são microrganismos capazes de viver em condições extremas e a Amanda é especialista em extremófilos marinhos de ilhas vulcânicas da Antártida. Lá existem fumarolas submarinas habitadas por micróbios adaptados a um ambiente com variação extrema de temperatura. Ela destaca o problema de conceber como microrganismos poderiam se adaptar às pressões muito altas que o oceano de Europa deve ter.  Amanda: Aqui na Terra, falando de extremófilos, a gente já encontrou vida nos mais extremos possíveis, desde a profundidade máxima do oceano até a mais alta atmosfera. Só que a profundidade máxima do nosso oceano é perto de 11 quilômetros, que fica naquela região das fossas marianas. Em Europa, é estimado que o ponto mais fundo seja ali perto de 100 quilômetros, então é 10 vezes quase mais profundo do que a nossa maior profundidade. Então, é um desafio a gente tentar entender como uma forma de vida ali poderia sobreviver a uma alta pressão como essa. Danilo: A Maria Eduarda Nascimento é doutoranda orientada pela Amanda, também no Instituto Oceanográfico da USP. A pesquisa dela envolve criar modelos computacionais para entender como possíveis comunidades de microrganismos poderiam subsistir no interior de oceanos de subsuperfície de luas geladas por meio de quimiolitoautotrofia – que é um nome sofisticado para descrever como alguns micróbios aqui na Terra se alimentam de compostos inorgânicos – como minerais e rochas – sem precisar de oxigênio e da luz do Sol. Os oceanos das luas geladas podem estar em contato com um interior quente e isso, dependendo dos elementos e compostos disponíveis, pode sustentar vida microbiana quimiolitoautotrófica. A gente vai falar disso daqui a pouco, porque a Maria também conversou comigo sobre alguns dos instrumentos da Europa Clipper. Maria: Ela tem o REASON, que é um radar para ver o quão grande é essa crosta de gelo e a estrutura. Ele tem um magnetômetro que é pela deformação no campo magnético que a gente sabe que tem um oceano, que a água salgada do mar acaba mexendo nesse campo eletromagnético, que a gente sabe que os elétrons da água salgada criam essa deformação no campo. Então a gente tem esse, que daí vai dizer quanto profundo é, vai dizer quão realmente muito profundo é. Qual é a salinidade? Vai ter um espectrômetro de massa também na Europa Clipper, então vai analisar esses gases na atmosfera por espectrometria. Danilo: A Clipper não vai ter como procurar diretamente por sinais de vida, buscando bioassinaturas, mas vai ser capaz de colher dados que vão poder indicar se o oceano é habitável ou não. Morando há décadas nos Estados Unidos, a Rosaly fala das bioassinaturas no inglês, biosignatures. Ela também falou sobre alguns dos instrumentos da Europa Clipper. Rosaly: Tem um que nós chamamos MASPEX, que é um espectrômetro de massa. Ele vai poder analisar gases perto de Europa. Se tiver pluma trazendo material do interior, isso vai ser uma beleza. Se não tiver pluma, aí depende de quanto material deve ter saído do interior. Também tem um Surface Dust Analyzer, que pode analisar partículas de poeira, dust é poeira. E existem sempre em todos os planetas e luas pequenos impactos de micrometeoritos e que estão colocando para fora partículas da superfície de Europa. Então, esse instrumento vai analisar a composição dessas partículas. E também, se tiver pluma no interior, colocando material para a superfície, também esse instrumento vai ser muito importante.  Nós vamos saber, por exemplo, mais sobre a espessura da crosta de gelo, se tem plumas trazendo material do interior para a superfície, se tem depósitos dentro da crosta de gelo que são, digamos, líquidos, que em vez de estar abaixo no oceano, estão mais perto da superfície. Está saindo algum material e nós sabemos que tem composição e cor diferente em umas regiões que chamam de Chaos Terrains, regiões caóticas, onde mais material veio do interior. E poder analisar a composição desse material, se tem material orgânico ou não. Então, [a sonda] vai também nos dizer muito mais sobre a lua Europa. Mas não é uma missão para detectar a vida, nem biosignature. Danilo: Diferentemente da Clipper, a JUICE (lançada pela ESA, a agência espacial europeia) não vai prospectar somente Europa, mas também Ganimedes e Calisto. Na verdade, o foco principal da missão da agência espacial europeia é a maior lua de todo o sistema solar, Ganimedes, a única que tem campo magnético próprio. A sonda vai orbitar essa grande lua, mirando entender sua estrutura interna, buscando mais informações sobre a extensão de sua crosta gelada, o volume de seu oceano, e caracterizar seu campo magnético. A sonda também vai fazer rasantes sobre Europa e Calisto para identificar locais mais interessantes para o pouso de futuras missões. O objetivo declarado da missão é entender as condições de habitabilidade oferecidas pelas três luas jovianas. Mas, claro, as luas de Júpiter não são as únicas que interessam para a astrobiologia. [Música] Danilo: Orbitando Saturno estão dois mundos que vêm chamando a atenção dos pesquisadores interessados na busca por vida fora da Terra há décadas: Titã e Encélado. Titã é a maior lua de Saturno – no sistema solar, ela só é menor do que a Ganimedes. Vamos falar de Titã daqui a pouco. Encélado é uma lua pequena – ela ainda tem tamanho mais do que suficiente para, com a própria gravidade, ter se tornado um objeto redondo, mas tem 15% do diâmetro da nossa Lua. A superfície dela, congelada, quase inteiramente branca com detalhes azulados, foi observada de perto pela primeira vez em 1980 e 81 quando as sondas Voyager visitaram o sistema saturniano. Se já era intrigante, Encélado se tornou um dos objetos mais interessantes do sistema solar com os indícios de que ela, também, possui um oceano de subsuperfície. A sonda Cassini, que começou a explorar o sistema de Saturno em 2004, observou Encélado ejetando plumas de materiais que devem compor esse oceano. Em três oportunidades, em 2008, 2012 e 2015, a Cassini deu rasantes – a uns 50 quilômetros de distância da superfície de Encélado – passando pelas plumas para analisar o que tinha ali. A Rosaly, que trabalhou na missão, falou um pouco sobre os achados. Rosaly: Encélado, o que é muito interessante é que esse líquido está em contato direto com o interior, a crosta do interior, porque foram detectados sais na pluma. Então, quer dizer que esse material está vindo direto do oceano. E nós sabemos que o oceano está em contato com o interior, que tem material orgânico também, sílica. Então, esse material está vindo direto do oceano até a superfície e você pode, digamos, colher esse material, voar pela pluma e colher o material.  Danilo: Com a Cassini, descobrimos indícios de que o oceano de Encélado tem materiais orgânicos e os seis elementos químicos essenciais para a vida: carbono, hidrogênio, oxigênio, nitrogênio, fósforo e enxofre. Eu também pedi para a Amanda explorar um pouco mais o que sabemos do oceano de Encélado a partir das plumas. Ela vai mencionar algo muito importante: as fontes hidrotermais.  Amanda: lá em Encélado é legal que tem umas plumas que são ejetadas em direção à superfície. E aí a Cassini passou de rasante nessas plumas que ficam geralmente ali no Polo Sul, de Encélado, e detectaram partículas de sílica. Esse tipo de partícula só poderia ser formado em temperaturas altas. Então, eles começaram aí uma discussão de que teriam fontes hidrotermais no fundo do oceano de Encélado. Isso é muito entusiasmante, porque a vida aqui na Terra, uma das grandes hipóteses, que é uma das mais aceitas pela comunidade científica, é que a vida teria se originado em fontes hidrotermais do oceano primitivo da Terra. Porque tem todos esses componentes químicos que geram um gradiente químico. A vida poderia obter energia, produzir energia a partir desse gradiente. Danilo: Até a década de 1970 ninguém sabia da existência das fontes hidrotermais no fundo dos oceanos terrestres. A crosta terrestre tem fissuras. Quando essas fissuras estão no assoalho oceânico, a água entra em contato com o magma próximo, o que gera verdadeiras chaminés, fumarolas. Nessas fontes, na escuridão do fundo oceânico, ecossistemas inteiros existem graças a microrganismos que conseguem produzir sua própria matéria orgânica a partir de substâncias inorgânicas, como compostos de enxofre, nitrogênio e ferro. A Amanda e a Maria falaram um pouco deles. Amanda: Tem não só micro-organismos bem específicos desses ambientes, mas até animais associados, porque os microrganismos sustentam a vida nesses locais, porque eles fazem um tipo de metabolismo que chama quimiossíntese. Que é um tipo de metabolismo que a gente tem todas as evidências de que era o metabolismo das primeiras formas de vida que existiram aqui. Eles conseguem obter energia a partir desses compostos químicos à base de enxofre, por exemplo. E aí, a partir dessa energia, eles conseguem fixar o CO2, que nem as plantas fazem a partir da luz. Fixam CO2 para produzir as moléculas orgânicas, eles conseguem, a partir da energia dessas rochas, desses compostos inorgânicos, fixar esse carbono e produzir, sintetizar essas moléculas orgânicas, então são produtores primários do fundo do oceano que sustentam a vida nesse oceano profundo. Então essas fontes hidrotermais são como se fossem oásis para essa vida de ambiente extremo em mar profundo. Maria: Eles estão lá respirando nitrogênio, respirando ferro, outros elementos. Então eles demonstram que essas similaridades, considerando o tempo também, por exemplo, Enceladus acredita que esse oceano esteja mais ou menos presente há um bilhão de anos, é tempo para a vida conseguir se adaptar a esse ambiente. Então, é plausível imaginar que se a gente tem um substrato quimiossintético, como por exemplo para a nossa vida aqui nas fontes hidrotermais, é plausível a gente imaginar que nesses outros mundos, onde existem essas condições alienígenas parecidas com o que a gente tem aqui, também exista vida.  Danilo: Além disso, o metano está entre os materiais orgânicos detectados em Encélado. Isso é mais um motivo para entusiasmo com o potencial de habitabilidade do oceano de Encélado. Amanda: Mas o legal do metano é que eles viram que provavelmente naquela camada fria de gelo tem clatrato de metano nas fissuras. Porque tem vários modelos que mostram a formação desse tipo de clatrato de metano, que são moléculas de metano que em volta tem moléculas de água congeladas, resumindo. E aqui na Terra a gente tem condições de oceano profundo e de subsuperfície pela alta pressão. Em temperatura baixa, a gente também tem hidrato de metano, que é abundante em algumas regiões de mar profundo, em subsuperfície. E aí, aqui na Terra, a gente tem nessas regiões de subsuperfície, eventualmente esse clatrato de metano pode vir mais em direção à superfície e exsudar esse metano. E a gente tem uma rica diversidade de arqueias que conseguem utilizar esse metano, arqueias e bactérias também, mas a gente vê que tem especificamente arqueias que conseguem metabolizar esse metano, consumir esse metano, são chamadas de metanotróficas. E aí é um grupo que hoje a gente já sabe que está espalhado na Terra, em todas as regiões de exsudação de metano, e que é muito adaptado a conseguir… Utilizar esse metano para obter energia nesses ambientes. Então a gente sabe que o metano também é um indicativo superlegal como uma fonte de energia para um possível metabolismo metanotrófico. [Música] Danilo: Eu não consigo decidir qual dessas luas é a mais interessante, mas eu sei que primeira a ter despertado minha curiosidade desde que li o livro Pálido Ponto Azul, do astrônomo Carl Sagan, é Titã. Então, vamos, finalmente, falar dela, a maior lua de Saturno. Titã foi observada pela primeira vez pelo astrônomo holandês Christian Huygens, com um telescópio que ele mesmo projetou, em 1655. Essa, que é a segunda maior lua do sistema solar, tem uma característica muito peculiar: Titã tem uma atmosfera muito espessa, e é tão densa que a pressão atmosférica em sua superfície é 50% maior do que a da Terra. Quando a sonda Voyager 1 passou pelo sistema saturniano em 1980, pela primeira vez os seres humanos puderam ver que a atmosfera de Titã oculta a superfície no espectro da luz visível. A Voyager também conseguiu caracterizar a atmosfera, composta principalmente de nitrogênio, com traços de metano e a presença de algo que vem semeando a imaginação de muita gente: moléculas orgânicas complexas. A sonda Cassini levou consigo um módulo nomeado em homenagem ao Christian Huygens. Quando a Cassini chegou perto de Titã, ela soltou a Huygens em direção à lua. Em janeiro de 2005, a Huygens desceu pela atmosfera muito densa de Titã, abriu um paraquedas e pousou. Por pouco mais de uma hora, a Huygens conseguiu fazer imagens da superfície, confirmando uma suspeita antiga dos astrônomos: como a Terra, Titã tem líquido estável na superfície. Mas não é água. Com temperatura média por volta de 180 graus Celsius negativos, a superfície de Titã tem lagos de hidrocarbonetos, ou seja, matéria orgânica. São lagos de metano e etano em estado líquido. Chove metano em Titã. Como? O Douglas explica. Douglas: Nessas temperaturas, o etano e o metano que fazem a atmosfera já conseguem ser condensados. Todo mundo já viu aqui um botijão de cozinha, de butano, butano propano, que dentro do botijão o gás está líquido. Você abre a torneirinha ali, a mangueira, sai líquido. E ele prontamente, quando chega na atmosfera, ele expande e forma gás. Então, quando você comprime gases, eles podem condensar e se tornar líquidos. Eles mudam de fase. A mesma coisa acontece lá. Com a alta pressão lá, a pressão é duas vezes a pressão aqui da Terra. E baixa temperatura, eles condensam, formam líquido. Então, ela tem oceanos, rios, lagos de metano e etano. E lentamente esse metano e etano vão evaporando, indo para a atmosfera. Na alta atmosfera eles se condensam de novo e formam nuvens. E essas nuvens podem chover ou nevar metano e etano. Então você tem um ciclo hidrológico, metanológico, completo de ciclagem de metano e etano na superfície.  Danilo: Quando esse material orgânico abundante em Titã interage com a radiação ultravioleta do Sol, ela forma polímeros orgânicos – moléculas compostas de cadeias muito extensas de carbono e hidrogênio. O Sagan deu o nome de tolinas para essas macromoléculas orgânicas muito abundantes em Titã. Douglas: Além disso, tem essas tolinas que formam hidrocarbonetos mais complexos. Por isso que normalmente o próprio [Carl] Sagan dizia isso: Titã pode não ser o melhor lugar para a vida como a gente conhece, mas pode existir alguma coisa de vida como a gente não conhece. Acima de tudo ela é um excelente laboratório de química prebiótica, porque você tem esse monte de moléculas orgânicas se formando, se complexificando e interagindo que pode dar os primeiros passos. Então grande parte das missões para ir para Titã ou para estudar Titã estão relacionadas com essa parte de química prebiótica. Esse é o principal argumento. Mas a própria missão que talvez vá em 2028, a Dragonfly, ela tem a proposta de procurar as duas coisas, de procurar resquícios, presença de água líquida, porque existe alguma água na superfície, mas normalmente na forma de gelo, ela vai buscar esse gelo e buscar por eventuais sinais de vida como a gente conhece, vida baseada em célula, coisas que a gente conhece. Danilo: A Dragonfly é uma missão da NASA em fase final de preparação. É uma espécie de drone do tamanho de um carro pequeno que vai explorar Titã. Deve até mesmo ser capaz de fazer pequenos voos pela atmosfera da lua. O lançamento da Dragonfly está previsto para julho de 2028 e a ela deve chegar em Titã em 2034. O que ela poderia encontrar lá, que seja de interesse astrobiológico? Será que Titã não poderia ter algum tipo de vida muito diferente da terrestre, com um maquinário bioquímico diferente? Douglas: A gente não conhece nada aqui na Terra que viva e que tenha metabolismo nessas temperaturas baixas, mas é cogitado. A Dragonfly também vai procurar por indícios de vida como a gente não conhece, algum desequilíbrio químico, alguma bioassinatura termodinâmica que possa indicar algum tipo de vida como a gente não conhece.  Danilo: Procurar pelo tipo de vida que a gente conhece, a terrestre, já é um desafio – se é que algo do tipo da vida terrestre existe fora da Terra. Um desafio ainda maior é procurar por vida como a gente não conhece. Tem muita coisa que a gente não sabe sobre a própria vida terrestre – como ela surgiu, por exemplo. Mas isso é o que sabemos que não sabemos – em outras palavras: é o desconhecido conhecido. Quando falamos em vida como não conhecemos, deve haver um espaço ainda maior de possibilidades que ignoramos e que nem sequer conseguimos conceber. É uma forma de ignorância dupla: nem sequer sabemos o que não sabemos. No próximo episódio, vamos voltar para a nossa vizinhança do sistema solar e olhar para um planeta gêmeo da Terra: Vênus. Ambos têm praticamente o mesmo tamanho, mas Vênus é um verdadeiro inferno, com uma superfície quente a ponto de derreter chumbo. Seria possível haver qualquer coisa viva lá? Na superfície, muito provavelmente não. Mas nas nuvens mais altas, a temperatura é bem mais amena. Em 2020, cientistas alegaram ter detectado fosfina, que aqui na Terra é produzida por seres vivos, uma possível bioassinatura nas nuvens altas de Vênus. Isso reacendeu o interesse astrobiológico no nosso vizinho infernal e novas missões estão em desenvolvimento para explorar a atmosfera ultradensa de Vênus.

Europa, Enceladus a další ledové měsíce patří mezi nejslibnější místa pro hledání mimozemského života. Nová česká studie ale upozorňuje na problém, který může budoucím sondám výrazně zkomplikovat práci: na jejich povrchu může vznikat extrémně pórovitý a křehký „nadýchaný led“.Vědátoři týmu, v němž je i Petr Brož, fčil ale ukázali, že za specifických podmínek se led netvoří jako pevná krusta, ale spíše jako jakási kosmická ledová pěna nebo kaše. Takový materiál má velmi nízkou hustotu, snadno se drolí a jeho mechanické vlastnosti se výrazně liší od běžného ledu, se kterým počítají konstruktéři přistávacích modulů.Objev je důležitý zejména pro budoucí mise k Europě a dalším ledovým světům. Pokud se podobný materiál na jejich povrchu skutečně nachází, budou muset konstruktéři přehodnotit návrhy přistávacích systémů i způsob odběru vzorků. Hledání života ve Sluneční soustavě tak možná komplikuje něco tak obyčejného – a zároveň neobyčejného – jako led...Vědátor vznikl jako spinoff olomouckého spolku studentů a popularizátorů vědy UP Crowd.

Something incredible is happening nearly a billion miles away — NASA has found new signs of life beneath the icy surface of Enceladus, one of Saturn's most mysterious moons. Scientists have detected complex organic molecules — the building blocks of life — shooting out of Enceladus' geysers, hinting at a vast ocean hidden under its frozen crust. Could alien microbes actually be living down there, surviving in the dark, warmed only by the moon's inner heat? In this video, we'll explore how NASA made this discovery, what it means for the search for life beyond Earth, and why Enceladus might be our best shot at finding living proof that we're not alone in the universe.

Exploring ocean worlds, like Europa, Enceladus or Titan, require electronics that can function in unforgiving conditions.

In 2024, researchers claimed to find something mysterious at the bottom of the ocean. It was “dark oxygen”—oxygen produced where there's no chance of photosynthesis. So what could possibly be producing it?Natural batteries—at least according to the scientists. This bizarre discovery seemed to upend everything we knew about the abyssal floor, had big implications for deep sea mining, and might even have helped explain the origin of aerobic life. But (and look, you know what we're going to say here) could there have been something a little more mundane explaining the findings?The Science Fictions podcast is brought to you by Works in Progress magazine.

SpaceTime with Stuart Gary Gary - Series 29 Episode 21In this episode of SpaceTime, we explore intriguing revelations about the search for life on Mars, the surprising effects of Saturn's moon Enceladus on its planet, and the monumental volcanic events that reshaped Earth's tectonic landscape.Life on Mars: A New PerspectiveRecent findings suggest that non-biological processes cannot fully explain the organic compounds found in Martian regolith samples collected by NASA's Curiosity rover. Published in the journal Astrobiology, the study indicates that life may have contributed to some of these compounds, challenging previous assumptions. The research involved evaluating potential non-biological sources and concluded that the abundance of organics on Mars could hint at past life, sparking renewed interest in the Red Planet's potential habitability.Enceladus' Electromagnetic InfluenceA fascinating study reveals that Saturn's icy moon Enceladus trails a wake of electromagnetic ripples extending over half a million kilometers, significantly influencing its giant host planet. Data from NASA's Cassini mission demonstrated how Enceladus' geysers contribute to energy and momentum circulation within Saturn's magnetic environment, marking a crucial discovery about the moon's role in the Saturnian system.Earth's Volcanic HistoryNew research highlights how Earth's largest volcanic event, associated with the Ontong Java Plateau, dramatically altered a major tectonic plate. The findings suggest that extensive volcanic activity led to significant physiochemical modifications within the oceanic plate, enhancing our understanding of plate formation processes and the environmental impacts of such massive eruptions.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrobiology, Geophysical Research Space Physics, Geophysical Research LettersBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.

In an area which is about 1/400th of the entire sky, the NASA Kepler spacecraft has discovered 30 Earth like planets which are likely to have liquid water on their surfaces orbiting distant stars. These planets are likely to represent a tiny sample of the habitable planets which exist in the Milky Way. In spite of our efforts to find them, the question remains where are the alien civilizations? In a recent talk given at the Division of Planetary Sciences meeting Dr. Alan Stern of the Southwest Research Institute suggests that perhaps the majority of worlds with biology and intelligent civilizations exist on interior water ocean worlds where their existence is hidden by the thick layers of rock and ice which separate them from the hostile vacuum of space. We know that in our solar system alone the moon of Jupiter Europa, Saturn's moon Enceladus, and perhaps several other small worlds are likely to have oceans of nutrient rich liquid water covered by a thick layer of rock and ice. We also know that Whales and Dolphins have larger brains than humans, communicate with each other, and exhibit other forms of intelligence. Advanced civilizations existing in ice covered seas may know little of the greater Universe, may find it difficult to consider transporting enough water to travel beyond their worlds, and may not think that it is possible to communicate with others of their kind who are similarly hidden under miles and miles of radiation absorbing ice and rock.

What if Europa’s seafloor isn’t alive with activity after all? This week on Planetary Radio, host and producer Sarah Al-Ahmed explores new research that reframes how scientists think about one of the Solar System’s most intriguing ocean worlds. Sarah is joined by Paul Byrne, associate professor of earth, environmental, and planetary sciences at Washington University in St. Louis. Paul is the lead author of a new study suggesting that the seafloor beneath Europa’s global ocean may be geologically quiet today, potentially lacking the hydrothermal activity often associated with habitable environments on Earth. Together, they discuss how scientists investigate places we can’t yet observe directly and why Europa remains a compelling world to explore regardless of what we find. Then, Bruce Betts, chief scientist of The Planetary Society, joins us for What’s Up to explain why Saturn’s moon Enceladus shows strong evidence for active hydrothermal vents beneath its icy crust, offering a fascinating contrast between two ocean worlds.

The Space Show Presents Dr. Antonino Del Popolo, Friday, 1-23-25Quick summaryThe Space Show hosted Dr. Antonin o del Popolo, an Italian astrophysicist, to discuss his book “We Are Not Alone: The Search for Extraterrestrial Life.” Dr. del Popolo explained the various theories on the origin of life, including panspermia and abiogenesis, and discussed the challenges in detecting extraterrestrial life, such as the distance between stars and the lack of confirmed signals from other civilizations. He highlighted the potential for microbial life on exoplanets and the importance of future telescopes like the James Webb Space Telescope in confirming its existence. The discussion also touched on the Fermi Paradox and the possibility of advanced civilizations, though Dr. del Popolo expressed skepticism about the likelihood of contact with such civilizations anytime soon.Detailed SummaryDavid and Antonino discussed the possibility of extraterrestrial life, with Antonio explaining that while there have been claims of life on other planets, such as the detection of dimethyl sulfide on an extrasolar planet, these claims have been discredited. He suggested that future telescopes like the James Webb Space Telescope might provide clearer evidence of life in the next 10 years. David mentioned his listeners' interest in UAP phenomena and the possibility of alien visitation, but Antonino dismissed these ideas as not supported by the scientific community.We formally started with introductions and small talk about volcanoes, with participants discussing locations like Sicily, California, and Idaho. David introduced the main guest, Antonino del Popolo, a physicist from Sicily with a new book on extraterrestrial life. Antonio explained that he would summarize the book's contents rather than use slides to save time for discussion. The host announced upcoming guests and programs, including Dr. Kothari, Dr. Ethan Siegel, and Greg Autry. The conversation ended with David introducing Antonio to discuss his book, “We Are Not Alone.”Antonino discussed his book on the origins of life, exploring two main theories: panspermia, where life originated elsewhere in the universe and was brought to Earth by comets, and abiogenesis, which posits that life arose from non-living matter on Earth. He also covered the iron-sulfur world hypothesis and the lipids world theory, highlighting the challenges in replicating cellular life in laboratories. Antonio concluded by discussing the potential for life in our solar system, particularly on moons like Europa and Enceladus, as well as on exoplanets, noting the discovery of the first exoplanet in 1991 and the ongoing search for habitable conditions beyond Earth.Antonino discussed the potential for microbial life on exoplanets, noting that while many planets in the habitable zones of their stars might support liquid water, confirming the presence of life is challenging due to the distance and limitations of current technology. David inquired about the difficulty in detecting life, to which Antonino explained that while spectroscopy can identify biosignatures like water and oxygen, only one exoplanet, K218b, has shown such signs, and it will take time to confirm life on more planets. Antonino also highlighted the challenges in detecting advanced civilizations, citing the “Great Silence” and the Fermi Paradox, which suggest that either civilizations are extremely rare or there are significant barriers to communication across vast interstellar distances.Antonino discussed the possibility of extraterrestrial life and civilization, mentioning Fermi's paradox and various theories such as the Great Filter and Kardashev's scale. He explained that recent studies, including work by Frank and Sullivan in 2016, suggest that technological civilizations have likely existed in the universe, based on statistical calculations of astrophysical and biological factors in the Drake Equation. John Jossy asked about the certainty of these studies, and Antonino clarified that while the calculations are statistically sound, the unknowns in biology could potentially invalidate the results.Antonino discussed the probability of life evolving on planets similar to Earth, noting that calculations for our galaxy suggest a high likelihood of inhabited planets, especially those orbiting red dwarfs. He explained that while exact probabilities are difficult to determine, estimates indicate around 6 billion such planets in our galaxy and potentially 10^22 in the universe. Antonino also addressed the perspective of believers, suggesting that the existence of life beyond Earth aligns with religious beliefs, while non-believers might find it harder to accept.The Space Show Wisdom Team discussed the probability of life and civilizations in the universe, with Antonino presenting estimates of 6 billion Earth-like planets around Sun-like stars, though Joe noted that only super-Earths have been discovered so far. They explored the concept of biosignatures, including carbon dioxide, water vapor, and methane, as indicators of life, with Antonino mentioning the discovery of dimethyl sulfur on the exoplanet K218b. The conversation concluded with a discussion about the possibility of past life on Mars, based on Viking lander experiments and recent findings of organic matter and water on the planet.Antonino talked about the presence of methane in the universe, explaining that while methane can be found on Jupiter and Saturn, its presence alone is not sufficient to prove the existence of life. He emphasized the need for precise biosignatures to confirm life and noted that microbial life could still exist despite the Fermi Paradox, which questions why we haven't detected any extraterrestrial civilizations. Dr. Ajay inquired about the historical context of the Fermi Paradox and the Drake Equation, and Antonino clarified that the paradox preceded the equation, though the exact timeline was not fully discussed.The team discussed the possibility of extraterrestrial civilizations and the Kardashev scale, which measures a civilization's ability to harness energy. Antonino explained that while the Fermi Paradox suggests no advanced civilizations in our galaxy, microbial life could still exist. Marshall proposed a theory about civilizations moving to galactic arms with more stars, and Antonino mentioned the concept of Dyson spheres as a way for advanced civilizations to harness energy from stars. Dr. Sherry Bell asked about the next steps if biosignatures were found, and Antonino explained that the James Webb Space Telescope would be used, with a more powerful telescope called Ariel planned for the future. He also noted that it would take a long time to confirm the existence of life on a distant planet, even with current technology.Antonino mentioned the time it takes to observe potential biosignatures with James Webb, explaining it could take several months to a year, and highlighted that the existence of life on K218b remains uncertain despite observations starting in 2023. He explored theoretical possibilities of faster-than-light travel using general relativity, though he considered such advancements unlikely within 50 years. The discussion also covered alternative chemistries for life, with Antonino noting that while silicon-based life is possible, carbon remains the most probable basis for life as it forms stable and complex structures. He concluded that microbial life likely exists in the universe, with intelligent life potentially following as evolution progresses, though he expressed skepticism about the likelihood of detecting extraterrestrial civilizations.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223 (Not in service at this time)For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

Are we alone in the Universe? It's surely one of the biggest questions out there. In our first episode of 2026 we chat to Dr Carly Howett, Associate Professor of Space Instrumentation in Oxford's Department of Physics. Specialising in the study of the 'icy worlds' found in our outer Solar System, Carly explains why she thinks one of Saturn's moons, Enceladus, could be a prime candidate for life, and shares the latest updates on how we might find it.

Let's look back at some of the biggest space news stories if 2025!Become a supporter of this podcast: https://www.spreaker.com/podcast/made-of-stars--4746260/support.

Not many planetary spacecraft get to shower off. But the Cassini spacecraft did – more than once. It flew through plumes of ice and water vapor from Enceladus, a moon of Saturn. The encounters helped scientists confirm that an ocean hides below the moon’s icy crust. Enceladus is a little more than 300 miles in diameter – roughly the distance from Los Angeles to San Diego. Its surface is completely coated with ice. That makes it the most reflective large body in the solar system, so it looks bright white. Much of that ice comes from more than a hundred geysers near the moon’s south pole. They erupt from deep cracks in the crust. They contain water vapor, water ice, hydrogen, grains of salt, and other compounds. Much of this material falls back on the surface. The rest of it escapes into space, where it forms a thin ring around Saturn. The geysers erupt from a global ocean. It’s buried about 20 to 25 miles below the surface, and it could be 10 miles deep or more. Hot, mineral-rich water could flow into the ocean through fissures on its floor. So the ocean appears to offer all the ingredients for life: liquid water, minerals, and a source of heat. That makes Enceladus a high-priority target in the hunt for life beyond Earth. Saturn is near our own moon this evening. It looks like a bright star, shining steadily through the lunar glare. But you need a good-sized telescope to pick out Enceladus.

(00:00:00) Cosmic Speedsters: Unravelling Our Solar System's Surprising Velocity and Enceladus' Organic Secrets (00:00:46) Our solar system is moving faster than expected (00:04:38) Organic molecules discovered erupting from Saturn's moon Enceladus (00:08:29) A new satellite launched to study Earth's oceans (00:13:49) The Science Report (00:15:52) Alex on Tech In this episode of SpaceTime, we uncover groundbreaking insights into Earth's mysteries and the cosmos beyond.Mysterious Structures in Earth's MantleA new study reveals that enigmatic structures within Earth's mantle may hold vital clues about why our planet evolved the conditions necessary for life. These massive formations, known as large low shear velocity provinces and ultra low velocity zones, reside at the boundary between the mantle and outer core, approximately 2,900 kilometres beneath the surface. The research suggests these anomalies could be remnants of Earth's formative processes, providing a deeper understanding of how elements from the core influenced the planet's cooling, volcanic activity, and atmospheric evolution, ultimately setting Earth apart from Venus and Mars.Unprecedented View of the Milky WayAstronomers have achieved a remarkable new perspective of our home galaxy, the Milky Way, with the largest low-frequency radio image ever assembled. This extensive survey, conducted using the Murchison Wide Field Array radio telescope in Western Australia, captures the intricate birth, evolution, and demise of stars across the southern hemisphere. The new image, which boasts double the resolution and tenfold sensitivity compared to previous observations, offers valuable insights into stellar interactions and the cosmic landscape, revealing patterns in star formation and supernova remnants.Successful Return of Stranded TaikonautsIn a significant development, the three Chinese taikonauts stranded in orbit after their Shenzhou 20 spacecraft was struck by space debris have safely returned to Earth aboard the Shenzhou 21 capsule. The crew's return marks the end of a six-month mission at the Tiangong space station, with their extended stay setting a new record for the longest duration in space for Chinese astronauts. The episode highlights the challenges of space travel and the rapid response by Beijing to ensure crew safety.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature GeosciencePublications of the Astronomical Society of AustraliaNew England Journal of MedicineBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

In this special interview episode of The Box of Oddities, Jethro sits down with acclaimed science journalist Becky Ferreira—author of the new book First Contact: The Story of Our Obsession with Aliens. Together they explore humanity's oldest question: Are we alone? Ferreira, whose work has appeared in The New York Times, WIRED, Popular Science, MIT Technology Review, and NPR's Science Friday, guides us through the deep history of alien speculation—from ancient Greek and Roman philosophers to Hopi star-people traditions to the modern UAP debate. Jethro taps into his inner UFO enthusiast as they dive into:• Why ancient cultures believed the sky itself was communicating with them• The earliest “alien life” theories from Christian and Muslim scholars• The Fermi Paradox, Drake Equation, and what science gets wrong about “Where is everybody?”• Water worlds like Europa and Enceladus, and why alien life may be hiding inside dark interior oceans• Whether interdimensional phenomena at places like Skinwalker Ranch could explain UAP encounters• How humans might emotionally—and chaotically—respond if we picked up an alien signal• The surprising ways religion is preparing for extraterrestrial discovery• Whether we'll make contact in our lifetime… and what form it might take Ferreira's insights blend cutting-edge astronomy with anthropology, psychology, and the strange human tendency to project our own fears and hopes onto the stars. Equal parts science, myth, and cosmic mystery, this conversation asks why the idea of alien life has been with us since the beginning—and why we can't stop looking up. Becky Ferreira's book First Contact is available now in hardcover, ebook, and audiobook wherever books are sold. Learn more about your ad choices. Visit megaphone.fm/adchoices

Hosted by Steve Nerlich. Dear Cheap Astronomy – What is the right message to send to the aliens? Keen listeners may be familiar with Cheap Astronomy's ongoing despair at Earth's lacklustre attempts at communication with the wider Universe. A few episodes back we ran through a history of deliberate communications to date, about 90 per cent of which have been music – well mostly digitized and some analog radio transmissions of music. Dear Cheap Astronomy – Can we drill through the ice and find life on Europa? Firstly, there are quite a few moons out there with suspected subsurface oceans – Ganymede and Calisto around Jupiter, Enceladus and Dione around Saturn – there's even a suspicion that Ceres, an asteroid rather than a moon, may have one. Everyone gets excited about Europa, because it's hot. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

In this second installment of Planetary Radio’s coverage from the 2025 NASA Innovative Advanced Concepts Symposium in Philadelphia, Pennsylvania, host Sarah Al-Ahmed highlights more of the technologies presented by the NIAC fellows. Mary Knapp of MIT Haystack Observatory shares her team’s Great Observatory for Long Wavelengths project, a space-based radio array designed to detect magnetic fields around distant exoplanets. Michael Hecht, also from MIT Haystack Observatory and principal investigator for the MOXIE experiment on NASA’s Perseverance rover, discusses Exploring Venus with Electrolysis, a concept that could turn Venus’s dense atmosphere into fuel for long-duration flight and exploration. Benjamin Hockman from NASA’s Jet Propulsion Laboratory introduces two projects: Gravity Poppers, tiny hopping probes that could map the interiors of asteroids and comets, and his team’s concept for a Venus balloon observatory. Finally, Justin Yim from the University of Illinois Urbana-Champaign presents LEAP, a legged robot designed to hop through the icy plumes of Saturn’s moon Enceladus in search of clues to its hidden ocean. Then stay tuned for What’s Up with Dr. Bruce Betts, chief scientist of The Planetary Society.

Send us a textConnect with Michele at https://www.bookclues.comWhat if the most important maps we'll ever draw are hidden under miles of water and thousands of PSI? We sit down with physicist and exploration roboticist James Bellingham to trace a life spent pushing past pressure, busting tethers, and building the autonomous systems that make the deep sea knowable.We start with the physics that rule the depths: hydrostatic pressure that crushes air spaces, why small pressure vessels survive better than big ones, and how neutral buoyancy and material science set the limits of human and machine. That frame sets up the cautionary tale of the Titan submersible—why carbon fiber shines in tension but falters in compression, how storage and certification matter, and what fast‑moving tech cultures miss when the ocean sets the terms. From there, we cut the cable. With radio waves blocked by conductive seawater, true autonomy became the only path. James explains how AUVs navigate without GPS, conserve energy, and work without ships, opening doors to safer, cheaper, and vastly wider exploration.The payoff is discovery. Only about 26 percent of the seafloor is mapped with modern bathymetry, so AUVs deliver first looks: mid‑ocean ridges where new crust is born, hydrothermal vents that power sunless ecosystems, and trench habitats that most of us will never see yet shape global cycles. We revisit shipwrecks as time capsules—Endurance and Titanic rendered in crisp 3D—and walk through crisis missions that advanced science: Deepwater Horizon's deep oil plumes metabolized by microbes, and the MH370 search that produced exquisite seafloor maps even without the plane. Each story underlines a simple truth: every dive, even the “unsuccessful” ones, expands the ocean's blueprint.Looking ahead, James sketches an ocean filled with quiet robot fleets running experiments, mapping chemistry and biology at scale, and building predictive skill for climate, fisheries, and coastal safety. The same playbook reaches outward to Europa and Enceladus, where subsurface oceans and likely hydrothermal vents could host life built on chemistry rather than sunlight. If the deep teaches anything, it's that curiosity thrives without Wi‑Fi—and that exploration gets smarter when we let machines take the pressure.If this journey into the hidden 70 percent sparked your curiosity, follow the show, share it with a friend who loves science, and leave a review with the deep‑sea question you want answered next.

In this episode of SpaceTime, we dive into the fascinating findings from Saturn's icy moon Enceladus, discuss delays in the Dream Chaser spaceplane's launch schedule, and celebrate NASA's breakthroughs in laser communications for deep space missions.Enceladus: Unveiling Complex ChemistryRecent discoveries reported in the journal Nature Astronomy reveal that Saturn's moon Enceladus is spewing complex organic molecules from its subsurface ocean. Data collected by the Cassini spacecraft during its mission has unveiled fresh insights into the chemical reactions occurring in this hidden ocean. The presence of organic molecules, including precursors for amino acids, raises the possibility that Enceladus may have once harboured conditions suitable for life. This episode explores how these findings could inform future missions aimed at further investigating Enceladus and its potential habitability.Dream Chaser Spaceplane: A Delay in LaunchSierra Space has announced that their Dream Chaser spaceplane's first free flight demonstration has been pushed back to late 2026. Originally designed as a manned spacecraft, Dream Chaser will now serve as a cargo transport for NASA's Commercial Resupply Services, delivering supplies to the International Space Station. The episode discusses the spaceplane's unique design, its cargo capabilities, and the future of its missions, including plans for a fully operational crewed version.Nasa's Optical Deep Space Laser Communications SuccessNASA's new Optical Deep Space Laser Communications project has surpassed all technical goals, paving the way for high-speed communications for future crewed missions to Mars. The technology, which successfully transmitted data over vast distances, demonstrated data rates comparable to broadband Internet services. This breakthrough enables faster communication for astronauts and could revolutionise data transmission in deep space. Tune in to learn more about the technology behind this ambitious project and its implications for future space exploration.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Astronomyhttps://www.nature.com/natureastronomyNASA Dream Chaserhttps://www.nasa.gov/dreamchaserNASA Optical Deep Space Laser Communicationshttps://www.nasa.gov/lasercomBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Enceladus: Unveiling Complex ChemistryDream Chaser Spaceplane: A Delay in LaunchNASA's Optical Deep Space Laser Communications Success(00:00) The Dream Chaser spaceplane set for another delay(00:48) Scientists have discovered new complex organic molecules spewing from Saturn's Enceladus(09:41) NASA says new optical Deep Space Laser communications project has exceeded all technical goals(17:29) Around a quarter of all press releases in the United States are probably AI generated(19:23) Companies failing to secure AI agents is causing security risks, warns expert(20:27) Gary Stuart says AI agents can be hacked and should be treated like humans
