Podcasts about Enceladus

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.

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.

Dr. Alfonso Davila (NASA Ames Research Center)Nov. 24, 2025In 2005, NASA's Cassini spacecraft made a groundbreaking discovery—it found massive plumes of ice and gas erupting from the south pole of Enceladus, a small but geologically-active moon of Saturn. These plumes are now believed to originate from a subsurface ocean of liquid water beneath the moon's icy crust, with conditions compatible with life, as we know it. The talk focuses on our current understanding of Enceladus' plume and subsurface ocean, and on past and future strategies to search in them for possible evidence of life.  Alfonso Davila is a Research Scientist in the Exobiology branch at NASA Ames Research Center, where he helps develop strategies to search for evidence of life beyond Earth.

(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

Exploring New Worlds: Dr. Sara Seager on Venus, Exoplanets, and Life Among the CloudsIn this episode of Red Planet Live, MIT astrophysicist Dr. Sara Seager takes us on a breathtaking journey through the frontiers of planetary science—from the acid clouds of Venus to the icy oceans of Enceladus, and even the methane lakes of Titan.Dr. Seager reveals why Venus, often overlooked, is one of the most thrilling destinations for future missions. She discusses the possibility of life within its sulfuric acid clouds, where stable biomolecules could persist despite the harsh chemistry. Her team's latest findings continue to show a phosphine signal with 4.8-sigma confidence, renewing excitement about potential biological activity in our neighboring planet's skies.We also explore the power of small but mighty missions, including Rocket Lab's upcoming Venus probe and Asteria, the CubeSat that proved precision astronomy can thrive on a shoestring budget. Dr. Seager shares her insights on TESS, the Transiting Exoplanet Survey Satellite, which at its peak was discovering up to 100 planet candidates a month—a quiet revolution in the search for other worlds.From Sub-Neptune exoplanets like K2-18b, showing signs of life with dimethyl sulfide in its hydrogen-rich atmosphere, to her visionary idea of Starshade, a large space telescope, Dr. Seager paints a hopeful picture of humanity's search for life beyond Earth.We also touch on her Seager Equation—a parallel to the Drake Equation—and her book The Smallest Lights in the Universe, which reminds us that discovery is as much about human connection as it is about science.Join us as we uncover why the most “underdog” worlds—and missions—often hold the brightest potential for discovering life in the cosmos.Dr. Sara Seager's Links:https://www.saraseager.com/professionalbiographyVenus :  https://www.morningstarmissions.space/https://www.projectstarshade.com/Sara's memoir The Smallest Lights in the Universe: A Memoirhttps://www.amazon.com/Smallest-Lights-Universe-Memoir/dp/0525576258

Stunning Aurora Display: Mark your calendars for November 5th to 8th, 2025, as a powerful geomagnetic storm is set to light up the night sky with breathtaking auroras. Classified as a G3 storm, this display will be triggered by a significant coronal mass ejection from the Sun, resulting in vibrant colors visible farther south than usual.The Fate of Earth: NASA's Transiting Exoplanet Survey Satellite (TESS) reveals alarming insights into the fate of planets orbiting sun-like stars. As these stars enter their red giant phase, they often engulf their inner planets. New data suggests that Earth's future may be more precarious than previously thought, as the Sun's expansion could ultimately consume our planet.Interstellar Object Risks: Recent research sheds light on the potential impact risks from interstellar objects (ISOs). As our solar system travels through the galaxy, it encounters a stream of these cosmic nomads. While the chances of a significant impact remain low, understanding their trajectories is crucial for planetary defense.Enceladus: A Hotbed for Life: Exciting new findings from the Cassini mission suggest that Saturn's moon Enceladus could be more promising for extraterrestrial life than previously thought. A newly discovered heat signature at the North Pole indicates a sustained global ocean, providing a stable environment for potential life.Blue Origin's Mars Mission: On November 9, 2025, Blue Origin will launch its first interplanetary mission, Escapade, using its new Glenn rocket. This NASA-funded mission aims to explore how Mars lost its atmosphere, providing critical insights into planetary habitability.For more cosmic updates, visit our website at astronomydaily.io.

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.

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.

HOW ARE MARINE ROBOTS SHAPING OUR FUTURE? inventor James Bellingham draws on decades of expeditions from the Arctic to the Antarctic to reveal how autonomous underwater vehicles (AUVs) are changing how humans explore and work in the ocean. These robots endure crushing pressures, freezing waters, and total darkness—collecting data vital for climate science, offshore energy, aquaculture, archaeology, and more. And the story doesn't end on Earth. Many of the same technologies being perfected in our seas will one day explore ocean worlds beyond our planet—including Jupiter's moon Europa and Saturn's moon Enceladus—places where liquid water lies beneath thick ice and where conditions may be right for extraterrestrial life. Finding life in these alien oceans would be one of the most profound discoveries in human history, changing how we see ourselves in the universe. From enduring fierce storms off Antarctica to developing robots that “think” and navigate on their own, Bellingham shares the inside story of working at the intersection of:Scientific discovery—expanding our knowledge of oceans on Earth and beyondCutting-edge technology—designing self-reliant machines for extreme environmentsSocietal choice—balancing the benefits of ocean technology with environmental, ethical, and economic considerationsBecome a supporter of this podcast: https://www.spreaker.com/podcast/arroe-collins-unplugged-totally-uncut--994165/support.

Dr. Morgan Cable is a research scientist at NASA Jet Propulsion Laboratory (JPL) in Pasadena, California. Her mission is to help answer one of humanity's biggest questions: are we alone in the universe?In this episode, we explore how NASA uses national parks as analog sites to study the landscapes of other worlds. Dr. Cable explains how these environments provide testing grounds for new technologies designed to operate on different terrains and in alien atmospheres.Named to the American Chemical Society's “Talented 12” in 2018, Dr. Cable has contributed to some of NASA's most exciting missions, including Cassini-Huygens, the Mars Perseverance Rover, Europa Clipper, and the Dragonfly mission to Titan.Our conversation also dives into the mysteries of the ocean worlds Europa and Enceladus—their habitability, potential for life, and why they captivate planetary scientists. And beyond her work, we talk about Morgan's adventurous hobbies, from surfing to mountain unicycling.It was an honor to host Dr. Morgan Cable on the podcast. Her passion, expertise, and energy are truly inspiring, and her contributions to planetary science are nothing short of remarkable.______________Follow us on social!Instagram: https://www.instagram.com/safetravelspodTikTok: https://www.tiktok.com/@safetravelspodYouTube: youtube.com/@safetravelspodSafetravelspod.com 

South African – born space physicist Michele Dougherty has been awarded the honorary title of Astronomer Royal. She becomes the first woman to hold the title in the 350 – year -old history of the role. Although her all-girls school in Durban did not offer science as an option, her father sparked her love for planetary science when he built a telescope in the back garden of the family home. After qualifying as a mathematician and moving to Germany for a fellowship, Dougherty changed focus and joined teams working on two major space missions. Dougherty played a big role in major discoveries in the solar system, including the revelation that jets of water vapour shoot out of one of Saturn's moons, Enceladus, meaning it may be able to support life. She even managed to convince Nasa to turn a spacecraft around to take a closer look! Mark Coles speaks to colleagues and friends who describe her as a supportive and strong team leader always happy to celebrate other people's successes.Presenter: Mark Coles Producers: Ivana Davidovic and Emma Gibson Editor: Nick Holland Sound Editor: James BeardPHOTO: Michele Dougherty/Imperial College London

Can the difficulty of interstellar travel the answer to the Fermi paradox? Or maybe it's the fact that we can only apply it to our galaxy and not further? Or maybe we can even find life in our solar system?

https://www.youtube.com/watch?v=DgQexNb0_0s From  Apr 15, 2017. Hosted by Fraser Cain. Did you hear that NASA just announced an important discovery in the quest to find life on other places in the Solar System? In this quick episode, Fraser details what NASA found on Saturn's Enceladus and Jupiter's Europa, and what it means for the search for life.   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!

Volcanoes aren’t just an earthly phenomenon. They’re found all across the Solar System. In this compilation episode of Planetary Radio, we explore volcanic and geothermal activity on planets, moons, and distant dwarf planets. You’ll hear from Rosaly Lopes, Nick Schneider, Rae Paoletta, Robbie Herrick, Scott Hensley, and Christopher Glein as they share insights into everything from lava flows on Venus and eruptions on Io to the mysterious heat signatures of icy bodies like Eris and Makemake. This journey spans over 20 years of Planetary Radio, featuring interviews hosted by both current host Sarah Al-Ahmed and founding host Mat Kaplan. Then, our Chief Scientist, Dr. Bruce Betts, returns for What’s Up and shares new findings from NASA’s Juno mission, which recently completed close passes by Jupiter’s volcanic moon, Io.
