Podcasts about exoplanets

An astronomer who's spent his career searching for alien life explains why he's confident extraterrestrials exist throughout the universe—yet remains skeptical that any UFO sighting has ever been proof of their visit to Earth.Support our Halloween “Overcoming the Darkness” campaign to help people with depression: https://weirddarkness.com/HOPEIN THIS EPISODE: If you ever attended grade school in the United States, you no doubt are more than familiar with the Mayflower and why the ship is so famous. But what you were not told in that classroom is about the mystery that took place on that voyage… on that very ship... that went unsolved for over three hundred years. (The Mayflower Mystery) *** June O'Brien has a problem. She loved toast… and her toast did a really good job of toasting bread. So what was the problem? Well… it appears her toaster was possessed by the devil. (June O'Brien's Satanic Toaster) *** It was June 1969, and less than a week from his seventh birthday; Dennis went camping with his dad, brother and grandpa for Father's Day weekend. The next day they bumped into some other Father's Day campers with kids and they all became quick friends. But while the kids were playing in the tall grass, Dennis disappeared… and was never seen again. (What Happened To Dennis Martin?) *** But first – how can you believe in extraterrestrials, but not be convinced of alien spacecraft? That's the argument being made by one well-known astronomer.

https://www.youtube.com/watch?v=yH4uczqmhQ0 From Jan 20, 2023. The James Webb Space Telescope took time away from finding the earliest galaxies or imaging incredible nebulae to test out its planet hunting capabilities. To say it was immediately successful would be an understatement. JWST is showing us that it can do almost anything in astronomy and cosmology.   Its latest trick is picking out an exoplanet candidate, confirming it exists and telling us about this alien world. LHS 475 is a red dwarf star 41 light-years away from our Solar System in the southern hemisphere constellation of Octans. And now we know a lot more about its planet, LHS 475 b.   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!

In this episode of SpaceTime, we celebrate a major milestone in exoplanet discoveries, unravel the enigmatic surface of Venus, and delve into the intriguing tale of interstellar comet 3I ATLAS.Exoplanet Count Surpasses 6,000Astronomers have reached an impressive milestone, confirming their 6,000th exoplanet, a testament to the rapid pace of discoveries since the first detection of an exoplanet in 1995. This milestone not only highlights the evolving understanding of our galaxy but also raises questions about the myriad of planetary types discovered, from rocky planets to gas giants. While the hunt for Earth-like planets continues, the methods employed to discover these distant worlds remain a challenge, with fewer than 100 exoplanets directly imaged to date. The future holds promise with upcoming missions, including NASA's Nancy Chris Roman Space Telescope, which aims to further uncover the secrets of our cosmic neighbourhood.Decoding Venus's Mysterious SurfaceScientists are making strides in understanding the peculiar features of Venus, particularly the crown-like structures known as coronae. A new study suggests these features may be the result of magma plumes attempting to break through the planet's crust. By mapping the paths of these magmatic bursts, researchers are shedding light on Venus's geological history and its stark contrast to Earth, despite their similarities in size and formation. The findings could help explain why Venus has become a hellish environment, devoid of life, while Earth thrives.Interstellar Comet 3I ATLASAstronomers have captured stunning new images of interstellar comet 3I ATLAS, revealing a prominent tail and glowing coma as it journeys through the inner solar system. These observations provide valuable insights into the comet's composition and behaviour, suggesting that it shares similarities with comets originating from our own solar system. As 3I ATLAS approaches the Sun, its increasing activity offers a unique opportunity for scientists to study material that formed around distant stars. The comet is expected to re-emerge in November, promising further observations and discoveries.www.spacetimewithstuartgary.com✍️ Episode ReferencesNASA Exoplanet Science Institutehttps://exoplanets.nasa.gov/Proceedings of the National Academy of Scienceshttps://www.pnas.org/Gemini Observatoryhttps://www.gemini.edu/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.Exoplanet Count Surpasses 6,000Decoding Venus's Mysterious SurfaceInterstellar Comet 3I ATLAS

Join astronomers Franck Marchis (SETI Institute) and Julien Girard (Space Telescope Science Institute) for a 30-minute live discussion unpacking NASA's exciting new findings from JWST. Just announced, JWST has revealed strong evidence of a Saturn-mass gas giant orbiting Alpha Centauri A—the Sun's nearest solar twin—located just 4 light-years away. The planet appears to orbit at about 1 to 2 AU, placing it within the star's habitable zone, though as a gas giant, it's not likely habitable itself. (Recorded live 8 August 2025.)

PREVIEW: GUEST NAME: Néstor Espinoza SUMMARY: John Batchelor converses with astronomer Néstor Espinoza about TRAPPIST-1e, an exoplanet 40 light-years away, and its perceived atmosphere. Espinoza dreams of an unlimited budget to launch a "fleet of James Webbs" to survey hundreds or thousands of habitable exoplanets, aiming to determine the commonality of life beyond Earth, an idea supported by others like Daniel Apai. 1906 WAR OF THE WORLDS

On September 17, 2025, NASA announced that the number of exoplanets, planets outside our solar system, tracked by NASA has reached 6,000. In the three decades since the groundbreaking detection of exoplanet 51 Pegasi b, the first confirmed planet orbiting a Sun-like star, astronomers have concluded that exotic worlds are everywhere.

Surprising Ozone Discovery on Mars: Scientists have detected an unexpected surge of ozone in Mars's polar vortex during winter, suggesting that the planet may have once had a protective ozone layer similar to Earth's.

Join communications specialist Beth Johnson for a live interview with astrophysicist Marc Hon (MIT), lead author of a new study revealing one of the most extreme exoplanets ever discovered — a small, rocky world that's literally disintegrating as it orbits its star. BD+05 4868 b is a Mercury-sized planet just 140 light-years away that's orbiting so close to its star, it's roasting at around 1650°C. The heat is intense enough to vaporize the planet's rocky surface, creating a massive comet-like tail of mineral dust stretching millions of kilometers across space. This rare discovery — only the fourth known disintegrating planet — offers scientists an unprecedented opportunity to study the geology of an alien world, and upcoming JWST observations could even reveal the chemical makeup of its interior. (Recorded live 17 July 2025.)

Win/win!In this episode of SpaceTime, we delve into some astounding revelations in solar physics and planetary science, including the extreme temperatures of solar flares, new insights into the formation of Jupiter's core, and the tantalising possibility of life evolving on nearby exoplanets.Solar Flares Hotter Than Ever ImaginedRecent research has revealed that solar flares can reach temperatures exceeding 60 million degrees Celsius, a staggering six and a half times hotter than previously believed. This groundbreaking finding, published in the Astrophysical Journal Letters, may provide answers to a long-standing mystery regarding solar flare spectral lines. The study suggests that positively charged particles, or ions, are heated more intensely than electrons during these explosive events, leading to a significant revision of our understanding of solar flare dynamics.New Insights into Jupiter's Core FormationA new study challenges previous theories regarding the formation of Jupiter's core, suggesting that a giant impact may not be responsible for the planet's dilute core structure. Instead, it appears that Jupiter's core formed gradually through the absorption of heavy and light materials during its evolution. This revelation, supported by advanced computer simulations, indicates that the core does not have a distinct boundary but rather blends smoothly into the surrounding hydrogen layers, reshaping our understanding of gas giant formation.Could Life Thrive on Nearby Exoplanets?Exciting new research posits that life may be evolving right now on some of Earth's nearest exoplanets, despite the high levels of radiation they receive. Scientists have drawn parallels between the harsh conditions on these exoplanets and early Earth, where life first emerged amidst extreme ultraviolet radiation. This research highlights the potential for habitability on planets like Proxima b, igniting further interest in the search for extraterrestrial life.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Monthly Notices of the Royal Astronomical Societyhttps://academic.oup.com/mnrasCornell Universityhttps://www.cornell.edu/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.Solar Flares Hotter Than Ever ImaginedNew Insights into Jupiter's Core FormationCould Life Thrive on Nearby Exoplanets?

For decades, Uranus has puzzled scientists. Unlike the other giant planets, Voyager 2’s 1986 flyby suggested the ice giant emitted no excess heat. Now, thanks to new analyses of Voyager data, decades of ground-based and space-based observations, and refined models, scientists have confirmed that Uranus does radiate more heat than it receives from the Sun. Host Sarah Al-Ahmed speaks with atmospheric scientist Michael Roman (Assistant Professor at the Universidad Adolfo Ibáñez in Chile) about his team’s new study showing Uranus emits around 12.5% more energy than it absorbs. Together, they explore what this means for our understanding of Uranus’s atmosphere, its bizarre seasonal cycles, the planet’s violent past, and why these findings strengthen the case for a future flagship mission to the Solar System’s overlooked ice giants.Stick around for What’s Up with Bruce Betts, Planetary Society chief scientist, for a look at Uranus’ newly discovered moon and a new random space fact.

https://www.youtube.com/watch?v=RucWv35XwD0 Hosted by Tony Darnell. From  Oct 11, 2023. Over the course of this show, we've talked many, many times about the Transit Method for detecting exoplanets.  It is simply the measure of a star's decrease in brightness as the star passes through our line of sight.  This once difficult measurement has now become commonplace and can even be done with advanced amateur astronomy equipment under a reasonably dark sky.   From this measurement, we can infer a few things about the planets passing by: we can get an indication of its size and if we measure several transits, we can get the period of the orbit around the host star.  We can also get an estimate of the period and eccentricity of the orbit by the width of the dip in the light curve.   But there is another, even more difficult measurement we can make using transit telescopes that are an important tool for learning about planets around other stars: exoplanet secondary eclipses.   Get all episodes: https://exoplanetradio.com Music by Geodesium: https://lochnessproductions.com   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!

In a relatively short period of time, exoplanets (planets around stars other than our Sun) have gone from an intriguing conjecture to an active field of scientific study, with over 5,000 confirmed discoveries. The task now is to move beyond merely accumulating new examples, and embarking on systematic studies of their properties. What fraction of stars have planets, how are they distributed in size and distance, what kinds of atmospheres do they have, are any promising homes for life? I talk with Natalie Batalha about what we've learned so far, and prospects for future discoveries.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/08/25/326-natalie-batalha-on-what-we-know-and-will-learn-about-exoplanets/Support Mindscape on Patreon.Natalie Batalha received a Ph.D. in astrophysics from the University of California, Santa Cruz.

In 2020, the YSES-1 system became the first directly imaged multiplanetary system around a Sun-like star. It features two giant exoplanets orbiting a star just 16 million years old. Now, the James Webb Space Telescope is revealing new insights into these distant worlds. Host Sarah Al-Ahmed speaks with Kielan Hoch, Giacconi Fellow at the Space Telescope Science Institute and principal investigator of the JWST program that captured these observations, and Emily Rickman, ESA science operations scientist at STScI and member of the JWST Telescope Scientist Team for coronagraphy. They explore what makes this system so unusual, including a dusty circumplanetary disk around YSES-1b and high-altitude silicate clouds in the atmosphere of YSES-1c. Later in the show, Bruce Betts joins for What’s Up to talk about how future telescopes like the Habitable Worlds Observatory could help us image smaller, colder, and older planets.

In this episode of SpaceTime, we uncover the latest astronomical marvels and pressing concerns in space science.The Cosmic Horseshoe: A Supermassive DiscoveryAstronomers have potentially identified the most massive supermassive black hole ever discovered, dubbed the Cosmic Horseshoe, which is estimated to be around 36 billion times the mass of our Sun. Located approximately 5 billion light years away, this colossal black hole distorts space-time and creates a stunning Einstein ring effect by gravitationally lensing light from distant galaxies. The measurement of its mass combines gravitational lensing and stellar kinematics, providing a rare glimpse into the formation and evolution of galaxies and their central black holes.Possible New Planet in the Alpha Centauri SystemExciting news emerges from the Alpha Centauri star system, where astronomers may have discovered a new planet orbiting Alpha Centauri A, the closest star system to our own at just 4.25 light years away. Using data from NASA's Webb Space Telescope, researchers suggest this Saturn-sized gas giant could be located in the habitable zone of a sun-like star. While the planet's gaseous nature may not support life, its proximity offers a unique opportunity to study planetary systems beyond our own, challenging existing theories on planet formation in binary star systems.The Satellite Proliferation DilemmaAs the number of satellites in Earth orbit continues to rise, astronomers are sounding alarms over the interference these satellites cause to vital scientific research. A study has highlighted the impact of Starlink's megaconstellation on radio astronomy, with significant radio emissions masking faint signals from the universe. This growing concern emphasizes the need for regulatory measures to mitigate interference and protect the integrity of astronomical observations.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical Societyhttps://academic.oup.com/mnrasAstrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Astronomy and Astrophysics Journalhttps://www.aanda.org/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

In this episode of SpaceTime, we delve into the cosmic drama unfolding in our universe, featuring a doomed exoplanet, new revelations about Mars, and the latest crew aboard the International Space Station.The Death Spiral of TOI 2109bAstronomers are closely monitoring the death spiral of TOI 2109b, an exoplanet located over 870 light-years away. This gas giant, nearly five times the mass of Jupiter, completes an orbit around its host star in just 16 hours, making it the closest hot Jupiter discovered to date. Researchers from Macquarie University have found that the planet's orbit is decaying, leading to three potential end scenarios: being torn apart by tidal forces, plunging into its host star, or losing its gaseous envelope to intense radiation. These findings provide valuable insights into planetary evolution and the fate of gas giants in close orbits.New Insights into Mars's Ancient SurfaceA recent study has identified a new type of iron sulfate on Mars, suggesting significant geothermal and chemical activity on the planet's surface. Researchers have characterized this uncommon mineral, which may represent a new type due to its unique crystalline structure. The discovery sheds light on how heat, water, and chemical reactions have shaped Mars, and indicates that the planet may have been more geologically active than previously thought. This research enhances our understanding of Mars's potential to have supported life in its past.New Crew Arrives at the International Space StationNASA has successfully delivered a new crew to the International Space Station aboard a SpaceX Dragon capsule. The crew, consisting of two Americans, a Russian, and a Japanese astronaut, will replace colleagues who have been aboard since March. As NASA considers extending crew stays from six to eight months to reduce costs, the new team is set to contribute to ongoing research and operations in low Earth orbit.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/1538-4357Nature Journalhttps://www.nature.com/nature/NASA's International Space Stationhttps://www.nasa.gov/mission_pages/station/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space Time Series 28, Episode 97 for broadcast on 13 August 202500:42 Astronomers are tracking the death spiral of a doomed planet more than 870 light years away12:06 ToI 2109 is one of the most interesting systems that we've got17:06 Scientists have identified a new type of iron sulfate on the Red Planet23:47 NASA has delivered four new crew members to the International Space Station aboard SpaceX Dragon25:10 New study claims consuming three fries a week increases risk of developing type 2 diabetes26:13 Google about to offer AI study tools to college students for free29:53 You've got to check for updates on all your Apple devices

From October 9, 2013. Nothing lasts forever, stars live and die over the course of hundreds of millions to billions, and in the case of red dwarf stars, trillions of years. Planets are born from the remnants of their parent stars and die over a shorter timescale. Life on those planets, if it exists, is presumed to be shorter still, governed entirely by the environments provided by the combination of the star and planetary characteristics. How long life lasts there ultimately depends on how long the star lives and how it dies.   Using our solar system as an example, since we know life arose here, how long will it last?  Astronomers think they have an answer.   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!
