https://www.youtube.com/watch?v=rTFbrCIkrfU Streamed live on Jan 12, 2026. Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest ) Humans live short lives, and from our perspective the seasons are something that come and go with perfect regularity. But astronomers know the terrible truth! And that there are cycles that slowly shift over tens of thousands of years, shifting the cycles and the Earth's climate. Today we'll talk about the Milankovich Cycles! The Earth's orbit, tilt, and other physical attributes aren't quite as constant as you might think! Come learn how long-term changes do and don't affect our climate.   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 May 2025. Today's 2 topics: - My Catalina Sky Survey teammate Hannes Gröller was asteroid hunting in the constellation of Ursa Major with the University of Arizona 90 inch Bok telescope on Kitt Peak when he discovered a faint moving object surrounded by a tiny gas and dust cloud called a coma. May 19, 2028 comet C/2025 D1  (Groeller) reaches its closest point to the Sun some 14.1 times the Earth-Sun distance and thus sets the record for the comet which stays furtherest from the Sun.After rounding the Sun comet C/2025 D1 (Groeller) will head back into truly deep space perhaps never to return.   - On March 3, 2024 my Catalina Sky Survey teammate Kacper Wierzchos was asteroid hunting with our 60 inch telescope on Mt. Lemmon, Arizona when he spotted a fuzzy object in the constellation of Draco.  After Kacper reported his discovery to the Minor Planet Center, observers in Arizona, New Mexico, and Tenerife confirmed it to be a comet and it was given the name C/2024 E1 (Wierzchos).  Kacper's discovery has a hyperbolic orbit indicating that after coming slightly closer to the Sun than the planet  Venus on January 21, 2026 it will be ejected from the solar system never to return.   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!

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com In this podcast (Episode 519) we talk with a special guest & long-time listener Clint Reading (from Nebraska, formerly from Idaho) about his astro-tourism trips to OzSky which is a biannual event for amateur astronomers from the northern hemisphere to have the opportunity to see the southern skies. We learn how to prepare for an astronomy trip to Australia, what to bring to get the most out of a week under the southern stars and how you can take advantage of these events. This is part of our New Years resolution to have more listener guests since there are so many of you doing astronomy activities that Shane and I can only dream of.    Introduction: So welcome to the show Clint! We've been chatting for years so it's great to speak in person. Can you tell us a little about where you are and how you became interested in astronomy? How have you progressed through the hobby? Are you in any clubs? Are you visual, imaging, both? What equipment are you using? You've had some interesting adventures I recall you went to Lowell a couple years back to a public event, how was that?   Main Show: Let's talk about your trip down south to OzSky (not to be confused with Ozzfest) So where is OzSky and what is it exactly? What is OzSky exactly? How is it organized? days/nights?  Speakers? Cost? Other amateurs? How did you plan for the trip? What did you take for equipment and observing guides? What equipment do they provide? Day trips?   Conclusion: Does anyone have anything to add? Thanks for joining us today Clint, we really appreciate it. Clear skies!   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!

Hosted by Steve Nerlich. Well… Cheap Astronomy confirms some mysteries are still mysteries! Dear Cheap Astronomy – Is warp drive looking any more possible? Well, no, insofar as it looks about as possible as it ever did, which is to say, it's probably impossible, but at the same time, it's best to never say never. As we've covered before, the nature of space-time precludes the possibility of faster than light travel simply because light travels as fast as it is possible to travel in space-time.   Dear Cheap Astronomy – What is X-17? X-17 is a mysterious and somewhat hypothetical particle. Somewhat hypothetical means there is a bit of evidence for its existence, although it's more a case of there being evidence of something unusual, rather than definitive evidence of a new particle that does something unusual.   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!

https://www.youtube.com/watch?v=cySk8O0iVjU Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest ) Streamed live on Jan 5, 2026. Freeman Dyson asked a fascinating question. What would it look like if a civilization was using all the energy coming from their star? And what form would this take? This introduced the concept of a Dyson Sphere, or more realistically, a Dyson Swarm surrounding a star. But if you're skeptical about the concept, you're in good company.   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 With special guest star Stella!   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!

As part of the NSF–DOE Vera C. Rubin Observatory First Look event in June 2025, Rubin announced that it had observed thousands of asteroids cruising about our Solar System, about 1,900 of which have been confirmed as never-before-seen. Within the flurry, a team of astronomers has discovered 19 super- and ultra-fast-rotating asteroids. One of these is the fastest-spinning asteroid larger than 500 meters (0.3 miles) ever found. In this podcast, Dr. Sarah Greenstreet discusses these fast spinning asteroids and what makes the Rubin Observatory ideal for discovering these types of objects.   Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Sarah Greenstreet is a tenure-track assistant astronomer at the NSF National Optical-Infrared Astronomy Research Laboratory (NOIRLab) and an affiliate assistant professor in the University of Washington's Department of Astronomy. She is also a member of the Rubin Observatory Community Science Team and has served as the Lead for the Rubin Observatory Solar System Science Collaboration's Near-Earth Objects and Interstellar Objects Working Group for the past seven years. Prof. Greenstreet's research program broadly focuses on orbital dynamics, characterization, and impacts of small bodies across the Solar System, with a particular focus on the rarest and most unusual asteroids.

https://www.youtube.com/watch?v=uijiic8crBQ Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest ) Streamed live on Dec 29, 2025. How big can a star get? This is a calculation made by one of the original pioneers of modern astronomy, Sir Arthur Eddington. And it's named after him, the Eddington Limit. Now, astronomers are finding examples of giant black holes early in the Universe, calling into question some of Eddington's assumptions. Let's explore this fascinating concept! Why are stars sphere-ish? Why do blackholes not eat everything? Why do pulsating stars pulsate? It all comes down to work done by Eddington at the beginning of the last century, and today we're going to look back at Eddington's work and all its applications in modern Astronomy.   This show is supported through people like you on Patreon.com/AstronomyCast  In this episode, we'd like to thank: Andrew Poelstra, BogieNet, Brian Cagle, Burry Gowen, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Sergey Manouilov, Siggi Kemmler, Sérgio 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 April 2025. Today's 2 topics: - On 27 December 2024 the Atlas group in Chile discovered an object now known as 2024 YR4 which appeared to have a significant chance of impacting Earth 22 December of 2032. The most recent data indicates the chance that 2024 YR4 impact Earth is about 1 in 25,000. These data indicate our moon has about a 1 in 700 chance to be impacted by this space rock. Even so astronomers are preparing for 2028 when 2024 YR4 will again come within the range of our instruments. Current data indicates 2024 YR4 will miss the Moon by less than 1,000 miles on 2032 December 22 giving astronauts there a Merry Christmas.   - As the Earth travels in its orbit around the Sun it collides with objects called meteoroids traveling through space. These tiny members of the solar system range in size from dust grains to objects a meter in diameter. By becoming part of the GMN's network, your data will help to discover and document meteor showers, aid in identifying the parent cometary objects, and in some cases help to identify locations to search for meteorites.   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!

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com This month in episode 516 we talk about the many things to see in the night sky including, carbon stars, double stars, 24P Schaumasse is a Comet that just cracks 8th magnitude making it visible in binoculars. We also detail how people can explore Jupiter through a telescope followed by many NGC and Messier Objects you can see in the winter sky.   Jan 1 - Struve 627 in Orion Colorful Double Star  Primary Star (A component): Yellow, golden-yellow, pale orange, or sometimes just white. Companion Star (B component): Bluish, blue-green, lilac, or pale green. Jan 2 - 40 Harmonia at opposition a large S-type (silicate) asteroid located in the inner region of the Main Asteroid Belt between Mars and Jupiter.  Discovery: It was discovered on March 31, 1856, by German-French astronomer Hermann Goldschmidt. Naming: It is named after Harmonia, the Greek goddess of harmony and peace, to mark the end of the Crimean War. Size: It has a mean diameter of approximately 111.3 kilometers (69.1 miles), making it larger than 99% of all known asteroids. Orbit: Harmonia orbits the Sun every 3.42 years (approx. 1,250 days) with a relatively low eccentricity of 0.046, meaning its path is nearly circular. Rotation: It completes one full rotation on its axis every 8.91 hours Jan 3 - Full Moon  - Quadrantid Meteors ZHR = 120 in Evening for NA observers - Moon interferes They are named after Quadrans Muralis, a 19th-century constellation that is no longer officially recognized. Constellation Origin: Lalande created the constellation to honor the mural quadrant, a large wall-mounted scientific instrument he and his nephew used at the observatory of l'École Militaire in Paris to measure star positions. Location: It was situated in the northern sky between the modern constellations of Boötes, Draco, and Hercules, near the "handle" of the Big Dipper (Ursa Major). Decline: In 1922, the International Astronomical Union (IAU) omitted Quadrans Muralis when it formalized the official list of 88 modern constellations, reassigning its stars to neighboring constellations Jan 5 - Sig Orionis colorful double star Sigma Orionis AB: This is the brightest component of the system and is a very close binary that appears as one star in most amateur telescopes. It is actually a triple system itself (Aa, Ab, and B). The primary stars (Aa and Ab) are highly massive, very hot blue stars that orbit each other every 143 days. The outer component (B) orbits the inner pair every 157 years. Sigma Orionis C, D, and E: These are additional companion stars that are farther from the AB pair and can be observed with small-to-medium sized telescopes, making the system appear as a beautiful quartet or quintuple system. Component D is magnitude 6.62 and is about 13 arcseconds from the AB pair. Component E is magnitude 6.66 and is approximately 41 arcseconds away. This star is notable as the prototype of the rare "helium-rich" stars.  Jan 6 - Regulus 0.5-degrees South of Moon Jan 8 - 24P Schaumasse Comet just cracks 8th magnitude, at Mag. 7.9 it is firmly a Bino comet Jan 10 - Last Quarter - Jupiter at Opposition - mag. -2.5, 46 arc seconds in Gemini GRS looks nice and Orange/Red NEB and SEB are prominent How to best observe?

https://www.youtube.com/watch?v=kGY4t683Xro Hosted by: Fraser Cain ( @frasercain ) and Dr. Pamela L. Gay ( @CosmoQuest ) Streamed live on Dec 22, 2025. Shortly after the big bang there were almost exactly the same amounts of matter and antimatter in the Universe, but there was just enough of a difference that we live in a matter-dominated Universe. But it didn't have to be that way! Explaining this mystery has been one of the great mysteries in astronomy, and today we'll see if there's been any progress! Why is the Universe the way it is? Specifically, why is it made mostly of matter? This is the question we'll look at today!   This show is supported through people like you on Patreon.com/AstronomyCast  In this episode, we'd like to thank: Andrew Poelstra, BogieNet, Brian Cagle, Burry Gowen, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Sergey Manouilov, Siggi Kemmler, Sérgio 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 March 2025. Today's 2 topics: - Astronomers have yet to discover any long lasting natural object, beside our Moon, which orbits the Earth, however, occasionally, a small space rock enters into a temporary dance with our home planet.   - My Catalina Sky Survey teammate Greg Leonard was asteroid hunting in the constellation of Hydra with our Schmidt telescope on Mt. Bigelow, Arizona when a fast moving unknown point of light passed through a set of his images. After Greg reported his observations to the Minor Planet Center for the next 10 days it was tracked by observatories in Arizona, Italy, Hawaii, Australia, and Argentina.  Citizen scientist H. A. Güler analyzed these data. The Minor Planet Center published the discovery of the near Earth asteroid 2018 CN41. The discovery was deleted when the object turned out to be a Falcon Heavy Rocket Upper stage with a Tesla roadster attached.   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!

Hosted by Dr. Jacinta Delhaize, Dr. Tshiamiso Makwela & Dr. Daniel Cunnama. In this "mid-season special" episode, we introduce you to an extraordinary giant radio galaxy nicknamed "Inkathazo", meaning 'trouble' in isiXhosa and isiZulu. We speak with Kathleen Charlton, a Master's student from the University of Cape Town, about the discovery of Inkathazo and her newly published work on the topic.   Kathleen spoke with us from the University of Oxford, where she was working with team members from the 'MIGHTEE' collaboration. She describes her experiences of first attending the AGN Populations Across Continents and Cosmic Time conference in Durham and then her research visit to Oxford. She also explains her research into both hydrogen absorption and giant radio galaxies.   In her newly published paper, Kathleen uses South Africa's MeerKAT telescope to study the strange physics going on in three giant radio galaxies (or GRGs for short). GRGs are behemoth galaxies spewing out plasma jets spanning millions of light-years. She nicknamed one of these 'Inkathazo', which means 'trouble' in the African Xhosa and Zulu languages, because of its "troublesome" properties. It has unusually bent plasma jets and resides at the center of a galaxy cluster. This raises intriguing questions about how these enormous structures form and evolve.   Kathleen describes how she used MeerKAT to create some of the highest-resolution "spectral age maps" of giant radio galaxies ever made. These maps track the age of the plasma across different parts of the GRG, providing clues about the complex plasma physics at work in these extreme galaxies.   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!

Hosted by Dr. Pamela Gay. A gentle fancy for the Christmas Season—an oft-told tale with a wistful twistful of Something that left the Earth with a wing and a prayer.   Earlier today, I had the stark realization that at the core of many Christmas stories is a core of sorrow or longing that must somehow be transformed into joy. Scrouge must learn charity. Ralphie longs for a bb gun and is betrayed by his joy. George is on the brink of suicide when his Guardian Angel intercedes. John McClane just needs to keep his wife alive (yes, Die Hard is a Christmas movie). Over and over, the holiday spirit can only enter on the wings of struggle.    This realization came to me as I looked for an old school (aka public domain) science fiction story to narrate for tomorrow's episode of 365 Days of Astronomy. The first story I came across (which I'll personally share tomorrow), was Arthur C Clarke's, "The Star" and it was too dark for that family-friendly podcast. Instead, I read "Second Landing," by Floyd Wallace. This story originally appeared in Amazing Science Fiction Stories.  Read it here: https://www.gutenberg.org/cache/epub/24958/pg24958-images.html   Written in 1960 by Floyd L. Wallace, this story is weirdly timeless and felt utterly necessary for this moment. Aliens learn of Earth from our broadcasts, and they fear we are on the verge of destroying ourselves with the bomb. To say more would be to reveal the plot.    I invite you to listen here and find hope in a world of too much darkness.

https://www.youtube.com/watch?v=2uvcumUc6Gc Hosted by: Fraser Cain ( @frasercain ) and Dr. Pamela L. Gay ( @CosmoQuest ) Streamed live on Dec 15, 2025. Atomic hydrogen is the raw material for stars, but there's a problem. It's cold & dark, but it can do a very rare trick, releasing a photon in a very specific wavelength, known as the 21 centimeter line. And thanks to this wavelength astronomers have mapped out star forming regions across the Milky Way, the Universe and into the Dark Ages! This forbidden transition of Hydrogen has led to the mapping of galaxy rotation, a cool classroom application of quantum mechanics, and weirdly no Nobel prize.

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 October 2025. Today's 2 topics: - Friday the 13th appears to continue to be a lucky day for the human race. When astronomers first discovered Apophis in 2004 it appeared possible that this 3 million ton, 1,200 foot diameter asteroid traveling at 8 mi/s could impact our planet creating a crater a several miles diameter and more than a half mile deep. Additional observations over the years have eliminated this possibility as Apophis streaks by closer than the communications satellites on that lucky Friday the 13th. Further, current calculations have reduced the chances of Apophis colliding with Earth in the next 100 years to about one in 100,000. However, over the millennia Apophis is likely to strike the Earth as does one it's size once every 100,000 years or so.   - Finding a meteorite that has traveled billions of miles through space to reach it's present location is exciting. It might even be worth real money.   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!

https://spacescoop.org/en/scoops/2528/whats-the-shape-of-a-supernova/ Rewritten & recorded by your editor, Richard Drumm. When you imagine an explosion in space, a supernova is usually what first comes to mind. But astronomers are still quite puzzled by some of the details of these cosmic fireworks. The typical supernova we often picture is really the end of a massive star's life. And a very dramatic ending at that!   During its existence, a star keeps its spherical shape through a very delicate balance between: - the outward pressure created by the core's nuclear heat, what we call the radiation pressure, and  - the gravity that compresses the star toward its center of mass.    We call this balance a state of hydrostatic equilibrium.   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!

http://www.astronomycast.com/archive/ From June 15, 2009. The surface of the Earth feels solid under your feet, but you're actually standing on a plate of the Earth's crust. And that plate is slowly shifting across the surface of the Earth. Over geologic timescales, plate tectonics has totally resurfaced our planet, bringing continents together, and tearing them apart. We know we have plate tectonics here on Earth, but what about other worlds in the solar system?   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 October 2025. Today's 2 topics: - Looking at the stars on a clear dark night, far from the artificial air glow humanity creates, have you ever wondered what it would be like to travel in truly deep interstellar space? 40 years after their launches in 1977, your representatives, the twin Voyager 1 and Voyager 2 spacecraft are in the vast space between the stars in our Milky Way galaxy. Aboard each Voyager is a Golden Record time capsule which is expected to last billions of years. This message from all of humanity is inscribed with greetings from Earth as well as sounds, images, and a decoding key which will enable any intelligent aliens which find a Voyager to discover who made it and where it came from.   - To reach the vicinity of the nearest star, 24 trillion miles away, in less than 20 years, an interstellar space probe would have to travel at a substantial fraction of the speed of light. Newton's laws of motion, published 300 years ago, predict that the greater the mass of an object the greater is the force required to increase its velocity. In order to alleviate the need for the virtually unaffordable amount of energy required to accelerate a normal sized spacecraft to a speed of 20% of the speed of light, the Breakthrough Starshot program has funded the creation of 'Sprite' , the world's smallest spacecraft.   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!

Astronomers have observed the longest-ever gamma-ray burst — a powerful, extragalactic explosion that lasted over seven hours. Rapid follow-up observations with the U.S. Department of Energy-fabricated Dark Energy Camera and the International Gemini Observatory provided crucial information about the possible origin of this extraordinary event and the galaxy that hosts it.   Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Jonathan Carney is a graduate student at the University of North Carolina at Chapel Hill, where he studies time-domain astronomy with a focus on tidal disruption events. His research spans the full pipeline of transient discovery and characterization, from developing machine learning models for the forthcoming Argus Array to conducting follow-up observations with NOIRLab telescopes. https://carneyjo.github.io/   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!

From December 3, 2025. The world we live on today has undergone dramatic change since it first formed, and time hasn't necessarily been kind. Earth has gained some weight (and a Moon) after a chance collision. A leaky gut led to some confusing internal structures. Here on the surface, mountains keep finding new ways to pop off and destroy surroundings. But scientists are helping us understand all these factors. Learn how in this episode of EVSN, and also hear about our latest tales from the launch pad.   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!

Hosted by Steve Nerlich. Immortality is hard work. Episode 6a: Staying Switched On It's difficult to achieve immortality unless you also achieve invulnerability, since even if you don't age or get sick you can still die from a natural disaster, or a murder, or whatever. Indeed, the longer you live the more likely some unexpected calamity may come your way. So, if your only immortal up until the point that something goes wrong and you die, then you're not really immortal.    Episode 6b: Hopping Universes. The day is coming when our Universe starts winding down towards heat death and our by-then close-to- immortal descendants will need to find a fresh young Universe to continue in. After all, here we living in a Universe that apparently popped of nowhere, quite literally, since the whole idea of a Universe is that it contains spacetime, so whatever nothingness that it did pop out of had neither space nor time dimensions.   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!

https://www.youtube.com/watch?v=nUyT46ZQYsc Hosted by Tony Darnell. From Feb 6, 2025. JWST Discovers Planet Formation in the Conditions of the Early Universe! Journey with the James Webb Space Telescope to the star cluster NGC 346, a vibrant region of star birth and potential planet formation. This image offers a glimpse into the early universe, where stars formed under conditions very different from our own Milky Way.   See how JWST's infrared vision reveals protoplanetary disks - swirling clouds of gas and dust around young stars - defying previous models of planet formation. Witness the evidence that planets can form in environments with fewer heavy elements than previously thought, expanding our understanding of how planetary systems like our own come to be.   This stunning image, a mosaic of data collected by JWST's NIRCam instrument, represents a breakthrough in our understanding of the cosmos. Discover the potential for new worlds and the endless possibilities that await as we continue to explore the universe.   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!

https://www.youtube.com/watch?v=l2kddFmnF5o Hosted by: Fraser Cain and Dr. Pamela L. Gay. Streamed live on Nov 8, 2025. Scientific expertise is under attack on all fronts with concerns coming from politicians and the public. While most of this is unwarranted and politically motivated, there can be germ of truth. Bad science does happen, but how? How is it that papers that very few believe still make it through peer review and to publication? Why do professors at prominent universities get quoted saying things that seem to be fiction? In this episode, we consider the case for letting potentially impossible things make it to publication.    This show is supported through people like you on Patreon.com/AstronomyCast    In this episode, we'd like to thank: Andrew Poelstra, BogieNet, Brian Cagle, Burry Gowen, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Sergey Manouilov, Siggi Kemmler, Sérgio 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 September 2025. Today's 2 topics: - The lunar roving, battery powered, 4 wheel drive "Moon Buggy" allowed astronauts on Apollo 15, 16, and 17 to travel 8 mph on the lunar surface with a maximum range of approximately 4.7 mi. Some of the rocks that these space travelers brought back, from the tiny area they were able to visit on the Moon, contained volcanic glass beads with trace amounts of trapped water inside of them.   - When the Japanese spacecraft Hayabusa visited the near Earth asteroid Itokawa in 2005 it found this 2000 foot by 800 foot elliptical world to have a variety of surface features. Instead of being a solid object like some asteroids, Itokawa is a rubble pile of boulders and pebbles held together by its tiny gravity. The total volume of pebbles seems to be comparable to the volume of large rocks and boulders which make up Itokawa , however, the depths of the pebbles or their concentration in the center remains unknown. Given this uncertainty, this asteroid appears to be made up of a million times more small particles than larger ones.    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!
