Podcasts about exoplanets

From September 20, 2023. Hosted by Tony Darnell. Episode 39. In recent years, scientists have made great strides in the search for extraterrestrial life. They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it.   The search for life however, is a little more involved than finding planets, measuring their location and distance around the star and figuring out their location within a habitable zone.  Astronomers need more information to learn if life may be there.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

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.

Who would win in a fight, 100 men or 1 gorilla? If you're thinking that question is too vague then you'll love Darren's analysis of the situation. Adam looks at claims that we've found evidence of alien life on an exoplanet called K2-18B. I'm not saying it's aliens but… listen to the episode to find out!

The search for life beyond Earth is no longer science fiction—it takes a lot of data, powerful telescopes and a bit of cosmic detective work. And at the center of this search is University of Chicago astrophysicist Jacob Bean. Bean was part of the team that made history by detecting carbon dioxide in the atmosphere of a distant planet using the James Webb Space Telescope—a major step forward in our ability to study exoplanets.Bean uses cutting-edge tools and discoveries that are reshaping how we think about planet habitability, biosignatures and our place in the universe. From potentially habitable exoplanets like K2-18b to false hopes like Gliese 486b, Bean shares why the atmospheres of these faraway worlds might hold the key to one of humanity's oldest questions: Are we alone in the universe?

From September 14, 2023. Hosted by Tony Darnell. Deep in the cosmos, NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered four new worlds orbiting a pair of young stars. These planets are providing scientists with a glimpse into a little-understood stage of planetary evolution - the time when atmospheres are being formed.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

What if we're wrong about the sun? Current consensus in the astrophysics community suggests that our planet orbits a burning ball of gaseous plasma - but there's compelling evidence that suggests the sun is actually made out of liquid metallic hydrogen. If this is true, it isn't just that we have a new model of the sun. All of astrophysics, from the Big Bang to the nature of white dwarf stars and neutron stars - will have to be rewritten. For this conversation about the true nature of the sun, we bring together two titans of science and industry. First is Dr. Pierre Marie Robitaille, who is the former director of MRI Research at the Ohio State University, where he designed and tested the world's first 8-Tesla MRI machine. Today, he is the champion of the liquid sun model of stars, which he presents in his formal scientific papers (https://vixra.org/author/pierre-marie_robitaille) and at his @skyscholar YouTube channel. Next is Jim Keller, a computer architect who has been a central player in the silicon revolution at DEC, AMD, Intel, Tesla, and Apple. Today, he is developing open-source hardware for artificial intelligence at Tenstorrent, as well as a fully automated semiconductor fabrication platform that will shorten chip production timelines to hours instead of months. Our conversation here closes a strange loop, set in motion by Keller coming across an early draft of Dr. Robitaille's “Forty Lines of Evidence For Condensed Matter - The Sun on Trial” (https://vixra.org/pdf/1310.0110v1.pdf). In the next few weeks, a new loop opens - Keller is a major supporter of our Beyond the Big Bang meeting in Sesimbra, Portugal which promises to be a long weekend of busting paradigms in astrophysics and cosmology.

On 9 January 1992, astronomers Alex Wolszczan and Dale Frail announced they had discovered the first two exoplanets, or planets outside our solar system, while working at the Arecibo Observatory in Puerto Rico. The two planets orbit a pulsar, a neutron star, 2,300 light-years away, in the constellation Virgo. We now know of the existence of nearly 6,000 exoplanets, but Poltergeist and Phobetor were the first to be confirmed.

The Webb Space Telescope picked up traces of dimethyl sulfide on planet K2-18b. On Earth, the molecule comes from microbes and phytoplankton. Also, researchers captured the first confirmed video of a colossal squid swimming in its natural habitat—almost 2,000 feet deep.Possible Signature Of Life Detected On Exoplanet—MaybeIn major galactic news, scientists may have detected possible signs of life on a planet right here in our galaxy. Is this one of the best hints we've gotten that alien life exists? Host Flora Lichtman gets into it with Anil Oza, the Sharon Begley Science Reporting Fellow at STAT and MIT. They discuss the latest in alien life, the Trump's administration cuts to the “indirect costs” of science funding, the largest map of a brain yet, and how salmon on anti-anxiety meds make bolder choices.A Colossal Squid Video? That's A Big DealThis week, scientists announced that they had captured the first confirmed video of a colossal squid in its natural habitat, recorded some 1,968 feet (600 m) below the ocean surface near the South Sandwich Islands. While there have been sightings of the colossal squid before, they have mainly been of individuals entangled with fishing equipment—and much of what is known about the elusive creatures comes from dead specimens.The video was captured by scientists on board the R/V Falkor (too) during an Ocean Census expedition searching for new marine life. As the remotely operated vehicle SuBastian descended towards the ocean floor, its cameras caught sight of a juvenile squid roughly one foot long (30 cm), and captured over a minute of high resolution video. The footage was later analyzed by experts and determined to be a colossal squid.Colossal squid are estimated to grow up to 23 feet (7 m) in length and can weigh as much as 1,100 pounds (500 kg), making them the heaviest invertebrate on the planet. They are not the same as the giant squid, an entirely different species, which can grow to be longer but are lighter and slimmer.Dr. Kat Bolstad, one of the squid experts the researchers sent their videos to for identification, joins Host Flora Lichtman to talk about the sighting.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Brian Keating explores the buzz around a possible sign of alien life on exoplanet K2-18 b, discussing the detection of dimethyl sulfide—a molecule that on Earth is linked only to biology. He urges caution, explaining that while the findings are exciting and headline-grabbing, the evidence is not yet conclusive and scientific skepticism is essential. Learn more about your ad choices.

Non-technical Talk by Prof. Jonathan Fortney (U. of California, Santa Cruz) Apr. 9, 2025Over 6000 planets have now been found around other stars, but we only have information about what their atmospheres are like for a few dozen.  NASA's powerful James Webb Space Telescope (JWST), which features a 20-foot mirror in space, is currently being used to understand planetary atmospheres.  Prof. Fortney explains how we can look for atmospheres around rocky planets the size of the Earth, and how his group and others are already measuring the abundances of molecules like water, methane, ammonia, and carbon dioxide in the atmospheres of larger planets, of sizes similar to Neptune and Jupiter.  And he tells us what astronomers are looking forward to in the next year or two with JWST.

Dune. Star Wars. Alien. Science fiction movies love alien worlds, and so do we. But how do scientists find planets outside our solar system in real life? One way is by looking for the stars that wiggle. Historically, astronomers have measured those wiggles via the Doppler method, carefully analyzing how the star's light shifts. Thanks to new data from the GAIA telescope, scientists have a much better picture of distant stars' wiggles — and the exoplanets that cause them.Want to hear more about exoplanet discoveries?

SpaceTime Series 28 Episode 37The Astronomy, Space and Science News PodcastExciting New Exoplanet Discovery, Evolving Dark Energy, and Insights into the Moon's Magnetic FieldIn this episode of SpaceTime, we uncover the discovery of a potential new exoplanet, TOI 2818C, located over a thousand light years away in the constellation Papus. This intriguing planetary candidate is estimated to be 10 to 16 times the size of Earth and orbits its host star in less than 16 Earth days. We delve into the innovative transit timing variations method employed by astronomers, which revealed the presence of this companion planet alongside the hot Jupiter TOI 2818b, and discuss the implications for our understanding of planetary formation in hot Jupiter systems.Dark Energy's Mysterious EvolutionWe also explore a groundbreaking study suggesting that dark energy may be evolving over cosmic time scales. Utilizing data from the Dark Energy Spectroscopic Instrument (DESI), scientists are piecing together the largest three-dimensional map of the universe, revealing hints that dark energy's influence could be changing. This discovery could challenge current cosmological models and reshape our understanding of the universe's fate.Dynamic Lunar Magnetic FieldAdditionally, we examine findings from China's Chang'e 6 mission, which indicate that the Moon's magnetic field has been more dynamic and lasted longer than previously thought. The analysis of lunar samples reveals a resurgence of the magnetic field around 2.8 billion years ago, suggesting that the Moon's interior remains geologically active, challenging earlier beliefs about its magnetic history.00:00 Space Time Series 28 Episode 37 for broadcast on 26 March 202500:49 Discovery of exoplanet TOI 2818C06:30 Transit timing variations method explained12:15 Implications for hot Jupiter planetary systems18:00 Evolving dark energy and the DESI findings22:45 Insights into the Moon's magnetic field dynamics27:00 Summary of recent astronomical discoveries30:15 Discussion on the health impacts of sugary beverageswww.spacetimewithstuartgary.comwww.bitesz.com

SpaceTime Series 28 Episode 35The Astronomy, Space and Science News PodcastDiscovery of a New Planetary System, Stable Trio of Icy Worlds in the Kuiper Belt, and the Fascinating Concept of White HolesIn this episode of SpaceTime, we delve into the groundbreaking discovery of a nearby planetary system orbiting Barnard's Star, the second closest star system to the Sun. Located just 5.96 light years away, this system comprises four small planets, each 20 to 30% the mass of Earth, revealing new insights into the potential for life beyond our solar system. We discuss the significance of these findings and the advanced techniques used to confirm their existence, including the innovative Maroon X instrument.Exploring the Kuiper BeltWe also explore the remarkable discovery of a stable trio of small frozen worlds in the Kuiper Belt, cataloged as the Algiera system. This intriguing find, made using data from NASA's Hubble Space Telescope and the Keck Observatory, could potentially be only the second three-body system identified in this remote region, challenging existing theories about how such formations occur.Theoretical White HolesAdditionally, we dive into the fascinating hypothesis suggesting that black holes may transition into white holes, ejecting matter and energy back into the universe. This revolutionary idea, rooted in quantum mechanics, opens up new possibilities for understanding the nature of black holes and the fundamental workings of the universe.00:00 Space Time Series 28 Episode 35 for broadcast on 21 March 202500:49 Discovery of a planetary system around Barnard's Star06:30 Significance of the findings and the Maroon X instrument12:15 Overview of the Algiera system in the Kuiper Belt18:00 Implications for our understanding of Kuiper Belt objects22:45 Theoretical concepts of white holes and their significance27:00 Summary of recent astronomical discoveries30:15 Discussion on health risks associated with slushy drinkswww.spacetimewithstuartgary.comwww.bitesz.com

Listen Now to 105 Future Now Podcast Our latest lunar lander, Blue Ghost, has just completed it’s 2 week moon mission, accomplishing 100% of it’s goal to deploy 10 different payload experiments, studying everything from the lunar dust to testing GPS signals and drilling deep into the regolith!  Not to be outdone, the Webb telescope has revealed CO2 in the atmosphere of distant exoplanets, orbiting the HR 8799 system, 130 light years from Earth. Could this be a life signature? Grok 3 helps us explore the possibilities more deeply, as well a new strange blue photograph of Mars with its moon Deimos in transit.  And there is news on Helium 3, mined from the Lunar surface, possibly the future fuel that will allow us to expand from a planetary to a solar system wide economy! Mining the future fuel Helium 3 from the surface of the moon Back on Earth, Silicon Valley engineer Mark Rober pits the camera-based full self-driving mode of a Tesla vs the Lidar-based auto-drive seen in Waymo vehicles. Which is better, and which survives the Wiley Coyote test?  And good news for our local eVTOL company, Joby Aviation for securing a London airport-to-airport route for their aircraft with Virgin Atlantic!  And we simply must share with you the latest discoveries of of Elon’s DOGE..Enjoy!

From September 12, 2023. Hosted by Tony Darnell. Based on our experience here on Earth, we know life here to be tenacious and ubiquitous. Even in the harshest climates, if we look hard enough, we can usually find some sort of life there. We are hoping the same is true on worlds around other stars, and recent research has begun looking into the question of whether life on other worlds could exist in the most inhospitable environs: the terminator zone of tidally locked planets.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
