Heat shields are one of the trickiest problems left to solve before we can have truly reusable spacecraft. So far we've seen different solutions, like ablative materials or ceramic tiles. But can a sweating heat shield be a solution? Finding out in this interview.

Can we refuel James Webb at L2 when it runs out of propellant? What will the Dragonfly octocopter see on the surface of Titan? Will discovering life on Mars stop us from going there? And in our extended Q&A+ on Patreon, what are space things I'm hoping to see in my lifetime? Answering all these questions and more in this Q&A show.

Terraforming Mars is usually considered in the realm of science fiction. But actually we have technology to start doing it in our lifetime and achieve some meaningful results it a timescale of tens of years, not thousands. What are they? Finding out in this interview.

Jupiter could have been twice as big in the past, the challenges of landing on the Moon, the record for the farthest galaxy has been broken. And in our Patreon edition, how the location of gas plays a role in star formation.

When did humans first think of aliens? Why is Oort cloud a sphere when the Solar System is a disk? Which space image is my favourite? And in our Q&A+ on patreon, is search for life only limited to looking for water? Answering all these questions and more in this Q&A show.

I dagens afsnit følger vi op på forrige afsnit, og taler om potentielt liv på exoplaneter. Og så har vi tid til en række andre spændende emner, som planet X/planet nummer 9, rumarkitektur, nedfaldende rumskrald og meget mere. Herunder at jorden har fået en sort boks!Her er Karina's notater til dagens afnsiot:1:Tegn på liv på Exoplanet K2-18b (?)K2-18b er en Exoplanet der kredser om stjernen K2-18, som er en rød dværg stjerne (124 lysår væk i stjernebilledet Løven). Den blev opdaget fordi den passerer foran sin stjerne i vores synsvinkel. K2-18b er i den beboelige zone omkring stjernen med et omløb på 33 dage. Den får cirka lige så meget lys fra sin stjerne som Jorden får fra solen. K2-18b har en radius der er 2.6 gange så stor som jordens radius og 8.6 gange tungere. Den er den første exoplanet som vi har undersøgt atmosfæren af. Det kann man ved at se på dens stjernes lys når det passerer igennem planetens atmosfære.Tidligere observationer med først Rumteleskopet Hubble og senere James Webb havde allerede afsløret, at K2-18 b har en atmosfære, der bl.a. indeholder vanddamp samt de kulstofholdige molekyler kuldioxid og metan – sidstnævnte populært kaldet naturgas. Ud fra disse resultater havde forskerne vurderet, at K2-18 b er en såkaldt hycean-planet – en planet med en atmosfære der er rig på hydrogen (brint) og har et globalt ocean af vand. Allerede de tidligere observationer med James Webb havde antydet forekomsten af DMS i atmosfæren på K2-18 b, men først med yderligere observationer er forskerne nu mere sikre i deres sag. De påpeger dog selv nødvendigheden af at foretage yderligere observationer med James Webb for at forekomsten af DMS og/eller DMDS kan definitivt bekræftes.DMS / DMDS:Det handler konkret om svovlforbindelserne dimethylsulfid (DMS) og/eller dimethyldisulfid (DMDS). Her på Jorden frembringes DMS og DMDS kun af levende organismer – primært mikrober som planteplankton i havet. Det er dog vigtigt at sige, at det på det foreliggende grundlag ikke kan bekræftes, at gasserne i K2-18 bs atmosfære er af biologisk oprindelse.Abiotisk oprindelse er også mulig!***** OPDATERING d. 3. maj 2025:En uafhængig analyse af James Webb-observationerne af K2-18 b ser ikke klare tegn på svovlgasserne DMS og/eller DMDS i planetens atmosfære. Yderligere observationer med James Webb er nødvendige for at afgøre om gasserne, der kan ses som et tegn på liv (en såkaldt biosignatur), er til stede på K2-18 b.Kilde:https://arxiv.org/html/2504.15916v1#bib.bib7 En anden dybere artikel:https://bigthink.com/starts-with-a-bang/evidence-biosignatures-k2-18b-flimsy/The problem with the detection:The “detection” of DMS in the near-infrared portion of the spectrum was very, very flimsy: at only 1-sigma significance, which means there's greater than a ~30% chance that the detection is a fluke. In all sub-field of physics and astronomy, a “1-sigma detection” is known as a non-detection; there is no meaningful signal seen here.While DMS on Earth may primarily arise from biological production mechanisms, it is found all throughout the Universe and, in those environments, is produced entirely by non-biological means. It's been found in the interstellar medium, including in the galactic center's large molecular cloud G+0.693-0.027. It's been produced abiotically in the laboratory right here on Earth (including since 1995) by simple processes, and can be made photochemically elsewhere in the Universe. And it's been found on comets as well, including on the famous comet 67P/Churyumov-Gerasimenko, which was the target of ESA's Rosetta mission.Hvad kan man egentlig med JWST?En artikel har undersøgt JWST's nøjagtighed og mener ikke at det teleskop er i stand til at give definitivt bevis for noget som dette. “Characterizing rocky or sub-Neptune-size exoplanets with JWST is an intricate task, and moves us away from the notion of finding a definitive “silver bullet” biosignature gas. Indeed, JWST results necessitate us to allow “parallel interpretations” that will perhaps not be resolved until the next generation of observatories.” https://arxiv.org/abs/2504.12946--------------------------------------------2: Hvornår er det okay at trykke på 'BIG NEWS' knappen?Back in 2021, the astrobiology community held a workshop on standards of evidence for biosignatures, which led to a community report discussing responsible standards of evidence and quantifying seven different levels of confidence for announcing biosignatures, with the lowest-confidence levels going to detections that cannot discriminate between different scenarios and mid-confidence levels going to definitive detections that cannot rule out abiotic pathways. To announce “we've found a biosignature” would require multiple, independent, unambiguous signatures of molecules that cannot be produced abiotically at all.Kilde: https://arxiv.org/abs/2210.1429317. April: I en Astronom Facebook gruppe:" This is an appeal. I am very sorry to bring this up in these difficult times, but I think that this latest astronomy news on extraterrestrial life goes very far beyond what in my opinion is responsible science communication. You could argue that this generates excitement in the public that is very much needed, but I think it is very damaging in the long run. Our colleagues from other fields will not take us serious anymore if we go on like this. We are doing fantastic stuff, also the group that has pushed this news. We don't need this, also not now."Og så blev der ellers diskuteret!Hvad jeg mener: Hvis man får opmærksomhed får man funding. Men når man overvurderer et resultat, så skader det troværdigheden. ----------------------------------------------------------------------------------3: Planet X eller Planet 9.Vi har måske fået vores første rigtige glimt af Planet Nine! Eksperter siger, at et mystisk objekt, som netop er blevet opdaget i to infrarøde himmelundersøgelser, er det hidtil stærkeste bevis for Planet 9. Planet 9 blev første gang foreslået i 2016 for at forklare de mærkelige baner for islegemer uden for Neptun, og man mener, at den er en massiv, fjern verden - måske mere end ti gange Jordens masse - som lurer langt uden for Pluto. Nu har astronomer under ledelse af Terry Long Phan fra National Tsing Hua University identificeret et svagt objekt i data fra rumteleskoperne IRAS (1983) og AKARI (2006), som ser ud til at have bevæget sig lige akkurat nok til at antyde, at den kredser om solen fra omkring 700 astronomiske enheder væk - ca. 65 milliarder kilometer. Baseret på dens infrarøde lysstyrke ville denne kandidat være mere massiv end Neptun og kan befinde sig i et vildt langstrakt kredsløb, der tager tusindvis af år at fuldføre.Selv om objektets identitet endnu ikke er bekræftet, skiller denne opdagelse sig ud, fordi den er synlig i begge datasæt - noget, som tidligere Planet Nine-kandidater manglede. Der er planlagt opfølgende observationer ved hjælp af kraftige teleskoper som Dark Energy Camera i Chile. Hvis den er ægte, kan Planet Nine give en hidtil uset indsigt i vores solsystems tidlige dage, herunder muligheden for, at den blev dannet nær de gigantiske planeter og blev kastet udad - eller blev indfanget fra et helt andet stjernesystem. Med næste generations observatorier som Vera C. Rubin-observatoriet og Nancy Grace Roman Space Telescope, der kommer online, siger astronomerne, at Planet Nines skjulesteder hurtigt forsvinder.https://arxiv.org/pdf/2504.17288https://videnskab.dk/rummet/hvor-taet-er-vi-paa-at-finde-planet-9/Bedste billede er sandkorn på en højtaler, der lægger sig i mønstre alt efter resonans frekvens af lyden der bliver afspillet. På samme måde hiver og trækker de store ydre planeter i de mindre objekter (planeter, asteroider, kometer) i solsystemet. Disse resonanser kan have afgørende for dannelse af liv som Uffe var inde på. De kan nemlig være afgørende for hvornår det sidste store bombardament skete.

One significant threat to life here on Earth is the possibility that a massive asteroid will collide with our planet and destroy life as we know it. To understand the possibilities, large surveys of the sky have found around 95% of potentially hazardous asteroids larger than a kilometer. Smaller asteroids, however, can also cause massive amounts of damage. Estimates range from 40 to 60 percent when it comes to asteroids over 100 meters in diameter, which would be considered city-killers. Even smaller asteroids, such as the 20-meter one that exploded over Chelyabinsk in 2013, can cause destruction and injury. The more asteroids we can find, the better our predictions and future protections will be. In light of this threat, scientists have used the JWST to detect 138 of the smallest asteroids (as small as 10 meters) ever observed in the asteroid belt. These tiny asteroids are important because they can become near-Earth objects (NEOs), posing a risk to Earth through possible impacts, including powerful explosions. By analyzing the size and frequency of asteroids, researchers found a significant change in the population of asteroids around 100 meters in size, likely due to collisions breaking larger asteroids into smaller ones. The observed asteroids originated from known asteroid families and were detected using advanced tracking and infrared imaging techniques. This research enhances our understanding of asteroid behavior and may aid in predicting and mitigating future asteroid threats. Join planetary astronomer Franck Marchis in a conversation with lead authors Artem Y. Burdanov and Julien de Wit as they discuss these smaller asteroids and what they can reveal about potential threats to our planet. (Recorded live 1 May 2025.)

The Kerbal Space Program is a fun game, but also an incredible tool for simulating a realistic space exploration program. According to a new paper, people playing the game can help develop innovative ideas that can turn into real missions, especially with the development and integration of reusable rockets like Starship and New Glenn.

Auroras em Netuno: Uma Descoberta HistóricaO Telescópio Espacial James Webb (JWST) fez história em março de 2025 ao capturar as primeiras imagens diretas de auroras em Netuno, o gigante gelado mais distante do nosso Sistema Solar. Esta descoberta marca um ponto de virada em nossa compreensão não apenas de Netuno, mas também dos processos auroras em planetas gigantes gasosos.As observações do JWST revelaram que a atmosfera superior de Netuno esfriou em várias centenas de graus nas últimas décadas, atingindo temperaturas próximas a 200 graus. Esta queda significativa de temperatura, combinada com a inclinação peculiar do campo magnético do planeta, pode explicar por que as auroras de Netuno permaneceram ocultas dos astrônomos por tanto tempo.Netuno também é conhecido por seus ventos extremos, que podem atingir velocidades superiores a 2.100 km/h, os mais rápidos registrados em qualquer planeta do Sistema Solar. Estas correntes de ar intensas, combinadas com formações de nuvens intrigantes, criam um ambiente atmosférico complexo que os cientistas ainda estão tentando compreender completamente.O Escudo Eletrodinâmico de Poeira: Revolucionando a Exploração LunarA NASA desenvolveu e testou com sucesso o Escudo Eletrodinâmico de Poeira (EDS), uma inovação que promete transformar a maneira como lidamos com um dos maiores desafios da exploração lunar: a poeira lunar abrasiva e eletricamente carregada.O EDS utiliza forças elétricas para levantar e remover o regolito lunar das superfícies, mantendo equipamentos críticos livres de poeira prejudicial. A tecnologia foi demonstrada com sucesso na superfície lunar durante a Missão 1 Blue Ghost da Firefly Aerospace, concluída em março de 2025.Este teste bem-sucedido representa um marco significativo na exploração espacial, abrindo caminho para missões lunares mais seguras e duradouras. A tecnologia pode ser aplicada a uma variedade de superfícies e equipamentos, incluindo painéis solares, radiadores térmicos, visores de capacetes e instrumentos científicos.A Nebulosa Hélice: O Fantasma de um Planeta DestruídoA Nebulosa Hélice, conhecida informalmente como o "Olho de Deus", abriga um segredo sombrio: dados do Observatório de Raios-X Chandra descobriram que a anã branca no centro da nebulosa, WD 2226-210, pode ter destruído um planeta que orbitava muito próximo a ela.A anã branca está emitindo raios-X de uma maneira que sugere a presença de material planetário sendo acretado pela estrela. Décadas de emissão constante de raios-X indicam que detritos de um planeta do tamanho de Júpiter estão caindo constantemente sobre a superfície da anã branca.Esta descoberta tem implicações profundas para nossa compreensão do destino final dos sistemas planetários, incluindo nosso próprio Sistema Solar. Em aproximadamente 5 bilhões de anos, nosso Sol seguirá um caminho evolutivo semelhante, expandindo-se em uma gigante vermelha antes de se transformar em uma anã branca.Uma Visão Interconectada do CosmosEstas três descobertas ilustram a natureza dinâmica e interconectada do universo. Elas nos lembram que o cosmos está em constante mudança e destacam o poder da curiosidade humana e da exploração científica para desvendar seus mistérios.Se você gostou deste vídeo, não se esqueça de deixar seu like, se inscrever no canal e ativar as notificações para não perder nenhum conteúdo sobre as maravilhas do cosmos.
