https://www.youtube.com/watch?v=iT3Pxmo1YLc Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest ) Streamed live March 6, 2026. Magnetars are a special type of neutron star with physics that defy comprehension. Magnetic fields so powerful they could strip you apart at an atomic level. But, where do they come from? So many mysteries to uncover about magnetars. Back in December 2004, a gamma rays washed out cameras and zotted satellites as a star on the other side of the Milky Way shifted around its magnetic fields. Magnetars are violent that way. In this episode of Astronomy Cast, Fraser and Pamela take on this tiny terrible monsters.   This show is supported through people like you on Patreon.com/AstronomyCast In this episode, we'd like to thank: Burry Gowen, Eric Lee, Jeanette Wink, Michael Purcell, Andrew Poelstra, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Joe McTee, Sergey Manouilov, Siggi Kemmler, Sergio Sancevero   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!

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From August 2025. Today's 2 topics: - Big Bear Solar Observatory is a unique facility operated by the New Jersey Institute of Technology. Its 1.6 meter Goode Solar Telescope is located on the north side of Big Bear Lake at an elevation of 6,760 feet above sea level in the San Bernardino Mountains of Southern California. Being surrounded by cold water at high altitude provides the site with exceptional atmospheric stability and thus the possibility of extremely high quality solar images. It is hard to predict the value of basic research, however, work like this will eventually enable scientists to better understand how solar flares and other activity in the Sun's atmosphere effect astronauts, communications systems, auroras, radio blackouts, geomagnetic storms, satellites, power grids, and more on our home planet.   - Recently, using data from the Japanese infrared telescope AKARI, Dr. Amos Y.A. Chen and his collaborators published a paper in the Publications of the Astronomical Society of Australia which predicts the approximate positions of two massive Planet 9 candidates. To arrive at their conclusions this team carefully searched the AKARI observations for objects which over the course of months change their positions relative to distant stars and galaxies. Further observations are required to determine if either of these move like a Planet 9 or if instead they are some other type of distant astronomical object.     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!

How do planetary systems form? If you wanted to observe them, where would you look and what would you look for? To find out, Dr. Charles Liu and co-host Allen Liu welcome Luke Keller, professor of Astronomy and Physics at Ithaca College, who together with his team has identified 9 of these early solar systems. As always, though, we start off with the day's joyfully cool cosmic thing: a recently published paper that determined that at any given time, it is likely that a couple of extrasolar objects like 3I/ATLAS and Oumuamua would be present in our solar system. The real issue is detecting them. For context, Luke, whose science has focused over the years on finding debris from solar systems, explains how protoplanetary discs can eject matter that ends up orbiting that star. He's especially fond of cosmic dust, “the catalyst for the formation of planets and asteroids and comets…” Then it's time for a question for Luke from the audience, from Elisa: “I heard that the James Webb Space Telescope sees infrared light. How does that work? Does that mean it couldn't see the Sun?” Luke breaks down the various wavelengths of light and our Sun. He also explains how the JWST works and why it never looks at the sun. It turns out that Luke has built a variety of astronomical instruments including imaging and spectroscopic tools with for large observatories. He's also used information from instruments like JWST in his studies of the formation of stars and solar systems. Luke explains how his teams search for preplanetary solar systems, what they're looking for, and where they're currently looking: associations of stars in the direction of the constellations Taurus, Scorpius and Chamaeleon. All told so far Luke and his team have identified 9 of these early solar systems. He then breaks down the current thinking on how planetary systems form from clouds of dust. He explains some of the processes that involves, along with the types of planets that may form. For our next audience question, Joan asks, “What do you think is the most interesting constellation?” Luke picks two: first, Ursa Major, aka “The Big Dipper,” because he grew up in Alaska and saw it all the time – along with “auroras all the time.” The second constellation he picks is Orion, aka “The Hunter,” because it contains some of the closest star forming regions of our galaxy. Luke unpacks the difference between “watching the sky” and “observing the sky” – and why he encourages the latter to both his students and the general public. And before the episode is over, we get to hear about Luke's live show, Spacetime, where he collaborates with poet David Gonzalez and guitarist Álvaro Domene in a stage performance that's equal parts astrophysics, poetry, and music.

In 1892 the world's largest telescope, the Lick Observatory's 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome.The adaptive optics research pioneered at Lick Observatory helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii.

This show has been flagged as Clean by the host. In our next look at the game mechanics for Civilization V we examine a new feature in Civilization 5, City-States. These are independent cities controlled by the computer that are also players to some degree in the game, and you can interact with them. And they are key to winning a Diplomatic Victory. Playing Civilization V, Part 9 - City States This was a newly introduced feature in Civ 5, and they play an important role in the game. They represent the small countries that are not running the world. They do not produce Settlers, so they do not expand beyond the one city, though that city can, and will expand its borders in a similar way to how your cities can grow. They do not start with a military unit, but they can produce military units and defend themselves. They can also build buildings in the city, but not Wonders. They do have a single vote each in the World Congress (or later the United Nations), making them a key to a Diplomatic victory. City States start out neutral with regards to the players, but your interactions with them can affect how they feel about you. For example, if you send units through their territory they will get hostile, but if you give them gifts they will get friendly. And if you wish you can go to war with them and take them over. This will affect your diplomatic relations with other players and other city states, but if you have decided on a war of conquest as your victory type, that won't matter to you, right? As mentioned, if you want to go for a Diplomatic victory you want to be allied with as many of them as possible to get their votes in the World Congress or the United Nations. But even if you don't need their votes, there are other benefits from friendly relations. There are two levels to friendly relations: Friendly, and Allied, and the benefits get better as the relations improve. City State Types With the expansions there are 5 types of City State: Militaristic, Maritime, Cultured, Mercantile, and Religious. The benefits you get are: Militaristic – If you are friends the city state will periodically gift you a unit, which will appear in your city which is closest to the city state. If you are allies the units will show up more often. Maritime – If you are friends they will add two food to your Capital city. If you are allies they will add one more food to every city you have. Cultured city states share their culture with you, at one rate if you are friends and at double the rate if you are allies. Mercantile city states give you an added 3 Happiness when you are friends. If you are allies you keep the added happiness, but in addition get access to a luxury resource that cannot be obtained any other way, and that also adds Happiness. Religious city states give you a one-time bonus of Faith when you first meet them, then provide added Faith per turn. Note that Cultured and Religious city states increase the amount of Culture or Faith they provide with each new era, so the earlier you develop your relations with them the better the benefit. Managing Relations With City States There is a mechanism in the game which keeps track of points to define your relations with city states. On this numerical scale, Neutral has a value of 0, Friendly 30 or above, and Allied 60 or above. In the other direction, once you go into negative numbers they become Angry, if if you go negative enough it becomes War. A city state can only ever have one ally. If only one player has more than 60 influence points, that player will become the patron of the city state and they will ally to that player. If two or more players have more than 60 influence points, the player with the most points gets the ally. As the game goes on, you may get a message that a city state you had as an ally has suddenly allied to someone else. This is the result of the other player gaining influence points in some way, often by gifts. You can also gain influence points by promising to protect a city state, but do this with your eyes open. If you do not follow through on your promise it will enrage the city state and you will lose a lot of influence with them. Your influence with a city state has a natural resting point at 0, or Neutral. That means that barring other factors, a positive number will fall over time, and a negative number will rise over time. So if you sent one of your units through their territory they will be angry for a period, but if nothing else happens they will return to Neutral. But on the other side, you don't stay allied with them forever unless you find ways to keep adding influence points. One way is to eliminate barbarian camps near to the city state. In fact, this is one exception to the rule about sending units through their territory. If you are doing it to attack the barbarians, you are seen as a protector, not an invader, and there is no penalty. Another way to gain influence is by completing a quest from a city state. Each city state you are in contact with will periodically give you a quest, and if you fulfill it you will gain influence points. This can include killing a barbarian camp or killing nearby barbarian units (though you can do that at any time, you don't need a quest). Some others include acquiring a Great Person of a certain kind, building a certain World Wonder, bullying another city state, finding a Natural Wonder, and so on. You do not need to fulfill a quest. For example, if your strategy calls for allying with other city states, you might want to pass on bullying another city state. There is no penalty for not fulfilling a quest, just a bonus when you do fulfill one. Another way to gain influence is with gifts. The most effective is Gold, and one large sum is more effective than several small ones. For a Diplomatic victory strategy, you should plan on having a large Treasury as you approach the end game so that you can buy allies in time for the crucial vote. You can also gain a small amount of influence points by gifting units. I make it a practice to do this whenever I have units that I don't want any longer. These could be obsolete units that have no upgrade path, for instance. I don't want to pay maintenance on them as that is a drain on my Treasury, and I could just delete them, but gifting them to a city state gives me a small amount of influence. Another way to get a big jump in your influence with a city state is to capture and then a return one of their Workers. Most often this happens when a barbarian has captured the Worker, and then you capture it. You have the option of keeping the Worker for yourself, and in the early game I would probably do that because the Worker is so valuable. But at a certain point I have enough Workers, and getting the 45 influence points for returning it starts to be more effective. Remember that you have to keep earning influence points to keep up your relations, so even if you get an ally of a city state for a few turns. it will naturally decay back to Neutral. By around the middle of the game if you playing well you can start to invest the resources needed to maintain your relationships. City States and War If you are allied with a city state and you get into a war with another player, a city state you are allied with will join you in the war. Of course, the same is true for the other player, so the war between the two players could also involve 3-4 city states dragged in as allies. You cannot make peace with a city state while it is allied to a player you are at war with. You have to first make peace with that player (or wipe them out if that suits you). However, if you can get more influence with that city state and supplant the other player you can get that city state to ally with you can turn around and attack your enemy. Generally a large cash gift can do this, once again showing the utility of a fat Treasury. Exploration You cannot have diplomatic relations with a city state you haven't met, so this reinforces the idea that you have to explore the map as soon as possible. Of course, you have to balance this with other priorities, such as expanding your cities and defending them, but finding the right balance is what all the Civilization games are about. On most maps this means you should be giving some attention to developing your naval power and technologies. There seems to be a bias to city states being coastal, and in many cases they are on small islands. Of course there are a number of motivations for exploring the map. First of all, you need intelligence of what you are up against with the other players. And unless you are on a very large land mass, you will want to find added lands for settlement. Finding Natural Wonders adds to Happiness in your Empire, so finding them all is important. And last, the unexplored sections of the map have a strong tendency to spawn barbarian units against you. Early on you cannot traverse Ocean tiles and need to stick to Coastal tiles. The unit here is the Trireme, which you can build once you discover Sailing. I will usually build 1-2 Triremes in a coastal city to go around the coast of the land mass I am on and scout out the situation. If another land mass or island is sufficiently close I can cross to it without entering an Ocean tile and extend my exploration. But to really explore the whole map you need to get to Caravels. This Renaissance Era unit becomes available when you discover Astronomy, and is essentially a naval scouting unit. It can enter Ocean tiles.

Dr John Bolton, once of the Radiophysics Laboratory in the CSIRO to conduct secret research on radar for the military, also helped pioneer radio astronomy after the Second World War. He was invited to Caltech to show them how to build radio telescopes — but then resigned and returned to Australia to build the legendary Parkes Telescope. Guest Jonas Zmuidzinas  Professor of physics  Director of Caltech Optical Observatories  Caltech PresenterRobyn Williams

Harriet Brettle studied finance, had several varied jobs in leadership, and now heads the Keck Institute for Space Studies at Caltech. Like the “professor of everything” Bob May from Australia, who once combined his mathematical physics with the head of the Bank of England, Harriet can take risks with projects based on knowing both what's worthwhile scientifically and sensible financially. Guest Harriet Brettle Executive director of the Keck Institute for Space Studies Caltech PresenterRobyn Williams

"Is this the real life? Is this just fantasy? Caught in a landslide, no escape from reality. Open your eyes, look up to the skies and see." There's something about space that captures the imagination of scientists and artists alike. Just ask astrophysicist Derek Ward-Thompson and astronomer Brian May (yes, THAT Brian May, guitarist of Queen). In their new book Islands in Infinity: Galaxies 3-D, they turn flat images of the galaxies to three dimensional spacescapes that leap off the page.  Host Flora Lichtman talks with Ward-Thompson and May about the enchanting nature of space and the collision of art and astronomy. And yes, they get into the music. Guests: Dr. Brian May is an astronomer and the guitarist of Queen. Dr. Derek Ward-Thompson is an astrophysicist at the University of Lancashire in England.

Welcome back to Astronomy Daily! In S05E55, Anna and Avery explore six fascinating stories from across the cosmos — from auroras on Jupiter's largest moon to the latest JWST galaxy reveal, a breakthrough solar storm warning system, a beautiful combined nebula image, Japan's ongoing rocket struggles, and Europe's ambitious plans for orbital repair robots.   Stories This Episode 1. Ganymede's Auroras Mirror Earth's Northern Lights Scientists using data from NASA's Juno spacecraft have revealed that Jupiter's largest moon Ganymede has fragmented, patch-like auroras remarkably similar to those seen on Earth. The research, led by the University of Liège and published in Astronomy & Astrophysics, suggests that the fundamental physical processes generating auroras may be universal across magnetised bodies in the solar system. Ganymede is the only moon known to have its own intrinsic magnetic field. 2. New Solar Superflare Forecasting System An international team has developed the first system capable of predicting when and where extreme solar storms are likely to occur, with up to a year's advance warning. By analysing 50 years of X-ray data, researchers identified a 1.7-year and a 7-year solar cycle whose alignment predicts high-risk periods. The current window (mid-2025 to mid-2026) is flagged as elevated danger. Published in the Journal of Geophysical Research: Space Physics. 3. Cat's Eye Nebula — Euclid and Hubble Combined NASA and ESA have combined imagery from the Euclid and Hubble space telescopes to produce a breathtaking new composite view of the Cat's Eye Nebula — the glowing remnant of a dying star about 3,000 light-years away in Draco. The image showcases the nebula's complex layered shells and intricate inner structure in unprecedented detail. 4. JWST Reveals Spiral Galaxy NGC 5134 The James Webb Space Telescope has captured a stunning infrared portrait of NGC 5134, a barred spiral galaxy 65 million light-years away. Webb's infrared capability pierces through galactic dust to reveal glowing stellar nurseries and the full cycle of star birth and evolution playing out across the galaxy's spiral arms. 5. Japan's Kairos Rocket — Safety Abort on Third Attempt Space One's Kairos No. 3 rocket was aborted just 30 seconds before liftoff on March 4 when a safety monitoring system detected unstable positioning satellite signals. Following two failed launches in 2024 and multiple weather scrubs this week, the company has yet to set a new launch date. The window remains open until March 25. A successful launch would mark the first orbital success for a fully private Japanese rocket. 6. Europe's Orbital Repair Robots European companies led by Thales Alenia Space are developing robotic satellites capable of refuelling, repairing and repositioning spacecraft in orbit. A demonstration mission is planned for 2028. With nearly 15,000 operational satellites now in orbit — most never designed to be serviced — the in-orbit servicing market could transform how we manage space infrastructure. Regulatory questions around liability remain unresolved.   Links & Further Reading Full show notes, images and source links: astronomydaily.io Listen on: Apple Podcasts | Spotify | Amazon Music | All podcast platforms Watch on: YouTube — Astronomy Daily Follow us: @AstroDailyPod on Twitter/X, Instagram, Facebook, TikTok, Tumblr Part of the Bitesz.com Podcast NetworkBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

NASA has announced a major restructuring of the Artemis program, reshaping the roadmap for returning humans to the Moon. At a February 27 press conference, agency leadership addressed the rollback of Artemis II following post–wet–dress–rehearsal testing and unveiled significant changes to upcoming missions, including shifting Artemis III from a planned lunar landing to a low-Earth-orbit rendezvous and integrated systems test. In this episode, you’ll hear remarks from NASA Administrator Jared Isaacman and Lori Glaze, Moon to Mars program manager and acting associate administrator for NASA’s Exploration Systems Development Mission Directorate. They explain what happened with Artemis II and why NASA is changing course. Then, host Sarah Al-Ahmed is joined by Jack Kiraly, director of government relations at The Planetary Society, and Ari Koeppel, AAAS science and technology policy fellow, to unpack the political and strategic forces behind this shift and what it means for the future of lunar exploration. In What’s Up, Bruce Betts, our chief scientist, looks back at Apollo 9, the Earth-orbiting mission that proved the Lunar Module could operate independently before NASA attempted a lunar landing.

Without additional data, the true nature of the rapidly northward moving point of light my Catalina Sky Survey teammate Carson Fuls had just discovered would have remained a mystery. Fortunately, this new object was tracked by telescopes in both Arizona and New Mexico. These data were used to calculate it's orbit around the Sun, estimate it's size, and give it the name 2017 UX5. When Carson first spotted this enormous 1,200 foot diameter space rock it was more than 30 million miles away traveling in our direction at 10.7 mi/s. It's orbit and that of the Earth's nearly intersect and at the closest point they are about two and one half times the Moon's distance from us apart. An asteroid the size of 2017 UX5 impacts the Earth every 76,000 years or so. According to the impact calculator developed at Purdue University and the Imperial College of London if 2017 UK5 is made of porous rock and came in at an angle of 45 degrees, it would start to break into pieces at an altitude of 41 miles and upon reaching the surface would create a crater 2.2 miles in diameter and 5/8 of a mile deep in sedimentary rock. The results 20 miles away from impact would be that of a 6.4 Richter Scale magnitude Earth quake followed by 176 mph air wind blast which would blow down 90% of the trees and collapse wood frame buildings. Fortunately asteroid hunters have not discovered any object like Carson's discovery with our number on it.

Off label uses for Pulsars… https://www.youtube.com/watch?v=4XMJBiJao6M Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) Streamed live on Feb 16, 2026. Pulsars are dead stars and fascinating in their own right, but astronomers can use their predictable rotation for exploring the cosmos in a series of amazing ways. We can detect gravitational waves, navigate the solar system, test general relativity and find exoplanets. Pulsars are the time keepers of the sky, with their precise ticking allowing researchers to track gravitational waves, find exotic planets, and study weird relativistic effects. Come learn about how pulsars can be used to explore our universe. Image credit: NASA/CXC/ASU/J. Hester et al., HST/ASU/J.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From July & August 2025. Today's 2 topics: - After the Earth the Sun is the most important object for human beings in the Universe.  It is the energy source which produces our food and is the source for all of the energy and motion around us except for geothermal and nuclear energy sources. The Sun is normally well behaved the exception being solar storms which can dump incredible amounts of energy onto the Earth. Scientists are working hard to understand solar super storms to enable humans to mitigate the trillions of dollars damage one could cause to our modern electronic technology.   - The US National Science Foundation's Daniel K. Inouye Solar Telescope is the worlds largest solar telescope. It is perched 10,000 feet  above sea level on the top of Haleakalā on the Hawaiian island Maui.   Its location and 4 meter mirror enables the Inouye to see details in the solar atmosphere as small in diameter as the island of Manhattan. 3D maps of the solar atmosphere produced by the Inouye's new Visible Tunable Filter will enable humans to put their equipment into a safe mode when necessary.   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!

Host | Matthew S Williams For more podcast Stories from Space with Matthew S Williams, visit: https://itspmagazine.com/stories-from-space-podcast ______________________Episode Notes Asteroid Mining: The Promise, the Problems, and the Philosophy Asteroid mining is one of those ideas that cycles in and out of public fascination — generating enormous excitement, then fading when people realize it won't happen within the next news cycle. But the concept never truly disappears, and for good reason. Near-Earth asteroids, numbering in the millions, contain staggering quantities of precious metals, rare earth elements, and water ice. Ironically, those same materials — iron, gold, platinum, nickel, and dozens of others — were originally delivered to Earth by asteroids during the Late Heavy Bombardment period some four billion years ago. We're essentially talking about going back to the source. The three main asteroid types — carbonaceous (C-type), silicate (S-type), and metallic (M-type) — each offer distinct resources. Beyond metals, the abundance of water ice in the solar system could relieve pressure on Earth's increasingly stressed freshwater supply and fuel deep-space missions. Philosophically, the implications are profound. Thomas More and Nietzsche both wrestled with why scarcity drives human value systems. Flood the market with space-borne metals and the entire economic architecture built on scarcity begins to crumble. Orwell saw it too — abundance erodes hierarchy. The first trillionaires born from asteroid mining might find their wealth meaningless almost immediately after making it. But the darker scenarios deserve equal attention. Redistributing consumption off-world doesn't eliminate it. Space debris, environmental degradation beyond Earth, and the very real risk of exploitative labor structures in off-world operations — echoes of colonialism and indentured servitude — are not science fiction. They're logical extensions of human patterns. The enthusiasm may ebb and flow, but asteroid mining remains an inevitable chapter in humanity's story. The real question is what kind of story we choose to write around it. ______________________ Resources   ______________________ For more podcast Stories from Space with Matthew S Williams, visit: https://itspmagazine.com/stories-from-space-podcast Hosted by Simplecast, an AdsWizz company.

Tiny Jupiter, Unusual Comet Behavior, and Gravitational LensingIn this exciting episode of Space Nuts, hosts Andrew Dunkley and Professor Fred Watson delve into some intriguing astronomical discoveries. They discuss the surprising news about Jupiter's size, the strange rotation of Comet 41P, and the fascinating concept of utilizing solar gravitational lensing for deep space exploration.Episode Highlights:- Jupiter's Revised Size: The duo explores new measurements from NASA's Juno mission that indicate Jupiter is slightly smaller than previously thought. They discuss the implications of these findings on our understanding of the gas giant's internal structure and atmospheric dynamics.- The Mystery of Comet 41P: Andrew and Fred reveal the unusual behavior of Comet 41P, which has experienced a significant slowdown in its rotation, potentially reversing its spin direction. They analyze the possible causes of this phenomenon and what it could mean for the comet's future.- Solar Gravitational Lensing: The hosts dive into the concept of using the Sun's gravitational field as a lens to observe distant exoplanets. They discuss the challenges of reaching the solar gravitational lens focal point and the technologies that might one day make such missions feasible.For more Space Nuts, including our continuously updating newsfeed and to listen to all our episodes, visit our website. Follow us on social media at SpaceNutsPod on Facebook, Instagram, and more.

On Earth living things are everywhere from the deepest ocean depths to the highest mountain tops. On our home planet RNA (Ribonucleic Acid) is a complex essential molecule involved in the process of translating genetic information into the working components of living cells. In a recent paper in the peer reviewed scientific journal Proceedings of the National Academy of Sciences , Dr. Yuta Hirakawa and his team of two coauthors report on their experiments to produce RNA under conditions similar to those which may have occurred in the early history of Earth and Mars.

Could a single ancient impact have briefly transformed one of the Solar System’s darkest moons into a cryovolcanic world? When Voyager 2 flew past Uranus in 1986, it captured the only close-up images we have of Umbriel, a heavily cratered, charcoal-dark satellite long considered geologically inactive. But one feature stands out: a bright ring inside the 131-kilometer-wide Wunda crater. In this episode, Sarah Al-Ahmed speaks with Adeene Denton, NASA postdoctoral program fellow at the Southwest Research Institute, about her team’s new study published in the Journal of Geophysical Research: Planets. Using shock physics simulations, Denton and her colleagues reconstruct the impact that formed Wunda crater to determine what Umbriel’s interior must have been like at the time. Their modeling explores whether impact-induced cryovolcanism can explain the bright deposits observed on the crater floor. Then, in What’s Up, Bruce Betts, chief scientist of The Planetary Society, joins Sarah to break down one of the key mechanisms that keeps icy moons from freezing solid, tidal heating driven by orbital resonance.
