Still looking. Hosted by Steve Nerlich. Dear Cheap Astronomy – Is there anything new on Planet 9? Well, not really and there is some growing skepticism about whether it's really there. Nonetheless, its original proponents, Mike Brown and Konstantin Batygin, still stick to their guns on the matter, though both agree Planet 9's existence must be considered speculative until it is actually observed.   Dear Cheap Astronomy – Is Nemesis really out there? Continuing the theme of hypothetical solar system bodies, Nemesis was proposed to be a small, dim and hence difficult to spot companion star of the Sun. Its existence was proposed in 1984 on the basis of a perceived 27 million year cycle in mass extinction events, where anything cyclical gets people thinking about orbits – and with a 27-million-year periodicity, you need a pretty big orbit.   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 October 23, 2008. Hosted by Fraser Cain & Dr. Pamela Gay. Everyone loves a theme. And this week we've collected together some of your questions about relativity. More light speed spacecraft, twin paradoxes, and the mixing up of gravity, time and mass. If you've got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.   - What would happen if you're traveling close to light speed through the solar system — would you mess it up? - If I watched my friend accelerate close to speed of light, will I see him get younger or age slower? - Can parts of the Universe be traveling back in time? - What form does relativistic mass increase take? - Why don't photons have mass? - Twin paradox:  Why is the "stay at home" twin's frame of reference preferred? - Does gravity equal time? - How can the state of an electromagnetic wave change when the wave exists outside of time? - How do we know the speed of light constant? Could it be different in different part of 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!

SpaceTime with Stuart Gary Gary - Series 29 Episode 10In this episode of SpaceTime, we explore groundbreaking developments in space exploration, including the imminent launch of the first nuclear-powered rocket, the merging of low mass dwarf galaxies, and the intriguing connection between Earth-like planets and gas giants.The Dawn of Nuclear Rocket TechnologyHistory is set to be made as NASA and DARPA prepare to test the world's first fully operational nuclear-powered orbital rocket. This innovative vehicle utilizes a nuclear thermal propulsion system that heats liquid hydrogen propellant through nuclear fusion, achieving nearly double the efficiency of conventional rockets. The test aims to validate reactor operation in orbit, potentially revolutionizing space travel by reducing transit times to Mars and allowing for larger payloads.Merging Dwarf Galaxies: A New DiscoveryA recent study published in the Astrophysical Journal Letters confirms that low mass dwarf galaxies can merge with one another. Observations of the Ursa Minor dwarf spheroidal galaxy reveal previously hidden stellar structures, suggesting that even the smallest galaxies experience mergers. These findings challenge traditional views on galaxy formation and evolution, indicating that interactions between dwarf galaxies may be more common than previously believed.The Connection Between Earth-Like and Gas Giant PlanetsAstronomers have found that rocky planets similar to Earth are more likely to exist in star systems that also contain large gas giants like Jupiter. This research, reported in Astronomy and Astrophysics, shows that cold Jupiters, which orbit beyond the snow line, play a significant role in the formation of super Earths in the inner regions of their planetary systems. The study offers new insights into the complex dynamics of planetary formation and the conditions that lead to the development of terrestrial planets.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal LettersAstronomy and AstrophysicsScience AdvancesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) NASA and DARPA prepare to test the first nuclear-powered orbital rocket(00:10:15) New study confirms mergers among low mass dwarf galaxies(00:20:45) Link discovered between Earth-like planets and gas giants(00:30:00) China breaks through barriers in nuclear fusion reactor development(00:35:20) The impact of ultra-processed foods on global health.

https://spacescoop.org/en/scoops/2529/a-thrilling-radio-message-from-a-nearby-red-star/ Hosted by our editor, Richard Drumm. About 130 light-years away from Earth there's an early M-Dwarf star called StKM 1-1262. Let's call it 1262… It's actually a common, ordinary star, the most common of stars, in fact. It's a red dwarf! They're also called 'Flare Stars' because they flare up frequently. Tempestuous little buggers! Not long ago astronomers got an exciting radio message of a sort from this star.  What did the message say?

After months of uncertainty, NASA science has been spared from the largest proposed budget cuts in the agency’s history. In this episode of Planetary Radio, host Sarah Al-Ahmed unpacks how Congress moved to restore near-full funding for NASA science and what that victory really means for missions, researchers, and the future of space exploration. Sarah is joined by Jack Kiraly, director of government relations at The Planetary Society, and Ari Koeppel, an AAAS science & technology policy fellow at The Planetary Society, to break down what passed in the FY 2026 budget, why the details matter, and how bipartisan support helped protect science programs across planetary science, astrophysics, Earth science, and heliophysics. The conversation also takes an honest look at the costs of the past year, from lost jobs and disrupted missions to shaken morale, and why rebuilding NASA’s scientific workforce will take time, even after this hard-won win. We also look ahead to what comes next as the FY 2027 budget process begins, and why sustained public engagement remains essential to protecting space science. Plus, Bruce Betts, chief scientist of The Planetary Society, joins us for What’s Up, where we discuss the recent early return of astronauts from the International Space Station, what’s known about the situation, and what it means for station operations.

In less than 24 hours, while observing with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona , I discovered two 25 foot diameter space rocks that theoretically can pass less than a quarter of the Moon's distance from us. After I posted my discovery observations on the Minor Planet Center's Near Earth Object Confirmation page one of them received immediate attention, as an incoming object, and was tracked by observers at 14 different observatories around the world. Scientists at the Minor Planet Center used these data to calculate it's 926 day orbital path around the Sun, estimate it's size, and give it the name 2017 TH5. 36 hours after I first spotted 2017 TH5 streaking through the night sky it came to less than 60,000 miles from the surface of our planet traveling at 7.6 miles per second. 8 hours and 49 minutes later it passed less than half a lunar distance from the surface of our moon. If 2017 TH5 would have been on an impact trajectory with Earth humans would have had time to prepare for a spectacular light show. Approximately once every 5 years a tiny asteroid like 2017 TH5 enters our atmosphere exploding at an altitude about 3 times higher than airliners fly releasing the energy of about 5,000 tons of TNT. Asteroid hunters are well on our way towards being able to issue a warning to stay away from doors and windows should a small space rock be discovered to be on an impact trajectory with planet Earth.

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!

My Catalina Sky Survey teammate David Rankin was asteroid hunting in the evening twilight with our 60 inch telescope on Mt. Lemmon Arizona when he spotted an unknown object in the constellation of Lyra. The largest telescopes on Earth will likely track David's discovery until it becomes too faint to observe in 2027 and catch it again when it again becomes bright enough to track in 2050. Fortunately it is extremely unlikely that it will strike Earth when it again comes close to our home planet in 2052.

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!

Utilizing data from NASA's Hubble Space Telescope and ground-based observatories, researchers traced the influence of Saguara as it interacts with Betelgeuse's outer atmosphere. This discovery sheds light on the star's peculiar brightness variations and its eventual fate as it nears a supernova explosion, which could occur at any time in astronomical terms.A Black Hole's Powerful FeastIn a remarkable observation, astronomers witnessed a black hole shredding a massive star in what is described as the most powerful event of its kind ever recorded. Known as a gravitational tidal disruption event, this phenomenon released energy equivalent to 400 billion times that of our Sun, surpassing even the most energetic supernovae. The event, cataloged as AT 2024WPP, offers new insights into black hole behavior and the dynamics of stellar destruction.BepiColombo's Journey to MercuryThe BepiColombo spacecraft is nearing its orbit insertion around Mercury after a seven-year journey. Launched in 2018, this multi-spacecraft mission will study Mercury's surface, magnetic field, and interaction with solar activity. The mission consists of two orbiters that will work in tandem to gather comprehensive data about this enigmatic planet, promising to enhance our understanding of planetary formation and evolution.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical JournalMonthly Notices of the Royal Astronomical SocietyEuropean Space Agency ReportsBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

Episode 227 In this episode of the Observers Notebook podcast, host Tim Robertson talks to Pranvera Hyseni — founder of Astronomy Outreach of Kosovo, driving force behind Kosovo's first National Observatory and Planetarium, and one of the most influential young voices in global astronomy education. Pranvera shares her remarkable journey from discovering the night sky in post-war Kosovo to becoming a worldwide leader in science outreach, earning international recognition and even having asteroid 45687 Pranverahyseni named in her honor. We explore how she built Astronomy Outreach of Kosovo (AOK) from a one-person dream into a national movement reaching tens of thousands of students, teachers, and families each year. She discusses the challenges of grassroots outreach, the role of female leadership in STEM, building a planetarium from the ground up, and how amateur astronomers everywhere can empower their own communities. Whether you're an educator, an amateur astronomer, a student, or simply someone who loves the night sky, Pranvera's story is a masterclass in what passion, persistence, and creativity can accomplish.

Our Solar System is wrapped in a vast, invisible bubble created by the Sun, a protective region that shields Earth and the planets from much of the radiation that fills our galaxy. But until recently, scientists have only had rough sketches of what this boundary looks like and how it behaves. In this episode of Planetary Radio, host Sarah Al-Ahmed is joined by David McComas, professor of astrophysical sciences at Princeton University and principal investigator of NASA’s Interstellar Mapping and Acceleration Probe (IMAP) and Interstellar Boundary Explorer (IBEX) missions, along with Matina Gkioulidou, a heliophysicist at Johns Hopkins Applied Physics Laboratory, former IMAP-Ultra instrument lead, and current IMAP project scientist and co-investigator. Now stationed at the Sun–Earth L1 Lagrange point, IMAP uses 10 instruments to study the heliosphere — the region where the solar wind collides with material from interstellar space. The mission does this by tracking energetic neutral atoms, particles that travel in straight lines from distant regions of the heliosphere, allowing scientists to map areas of space that spacecraft can’t directly sample. McComas and Gkioulidou explain how IMAP builds on the legacy of Interstellar Boundary Explorer, what makes this mission different, and why understanding the Sun’s influence across space matters not just for fundamental science, but for space-weather forecasting and protecting technology and astronauts closer to home.

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!

New Zealand's 4.5 million people are concentrated in three major population centers which to various degrees suffer from the modern plague of light pollution. However, most of New Zealand's large rural areas and land reserves, covering an area as large as the UK, have unpolluted natural night skies. A completely unique place to experience New Zealand's natural night sky is the Aotea [ Ah - yoh - tee - ah]-Great Barrier Island International Dark Sky Sanctuary. It encompasses New Zealand's, 110 square mile, sixth largest island, which is located about 62 miles from central Auckland. It is easily accessible by boat or a short airline flight. The island's 1000 residents are employed by agriculture and tourism. They value the natural night sky and function without externally generated electricity or street lights and fully support the preservation of their prestine night sky. In the daytime Great Barrier Island offers wonderful beaches and hikes. When the sun sets the night sky becomes alive with its own natural lights. Night sky measurements by Auckland Astronomer Nalayini [ Na - laa - i - ni] Davies and her collaborators have proved that the Great Barrier Island's natural night skies are second to none on planet Earth. Using the unaided eye, a set of binoculars, or a small telescope an observer on the Great Barrier Island is treated to spectacular views of the center of the Milky Way, the clouds of Magellan the nearest galaxies to us, the nearest stars, as well as numerous star clusters, meteors, comets, and other wonders of the natural night sky. Perhaps this unique spot deserves a place on your bucket list.

Since Russia launched its full-scale invasion of Ukraine, it has also escalated a shadow war against the West.

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.

What does it really mean to enter interstellar space, and what have we learned since humanity first crossed the invisible boundary between our Sun and the stars? In this episode of Planetary Radio, we explore the science of the heliosphere and the realm beyond with Linda Spilker, project scientist for the Voyager mission at NASA Jet Propulsion Laboratory. Drawing on decades of experience with the twin spacecraft, Spilker shares how Voyager reshaped our view of the Solar System’s outer frontier, from the nature of the heliopause to the unexpectedly rich structure of the local interstellar medium. We unpack what Voyager 1 and Voyager 2 have taught us about charged particles, magnetic fields, and cosmic rays beyond the Sun’s protective bubble, and why those measurements have upended earlier ideas about where the Solar System truly ends. Spilker also reflects on the mission’s extraordinary longevity, the ingenuity required to keep the spacecraft communicating across the vastness of space, and what Voyager’s legacy means for future journeys between the stars. Then, in What’s Up, Bruce Betts, chief scientist at The Planetary Society, places Voyager in context, showing how long-lived missions shape the bigger picture of space science and why observing longer can lead to some of our most profound discoveries.

Astronomy Cast Ep. 777: The Eddington Limit By Fraser Cain & Dr. Pamela Gay 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.
