Podcasts about Astronomy

On July 14, 2015, NASA’s New Horizons spacecraft made its historic flyby of Pluto, transforming our understanding of this distant world. Ten years later, we’re celebrating that iconic moment and the mission that made it possible. We begin with Alan Stern, principal investigator of the New Horizons mission, who reflects on the mission’s origins, its most surprising discoveries, and what comes next as New Horizons continues its journey through the Kuiper Belt. Then we check in with Adeene Denton, NASA postdoctoral program fellow at the Southwest Research Institute, who just returned from the “Progress in Understanding the Pluto System: 10 Years After Flyby” conference held at the Johns Hopkins University Applied Physics Laboratory. Adeene shares highlights from the event, which brought together scientists to explore new results from New Horizons, JWST, Hubble, and ground-based observatories on Pluto, Charon, and the broader Kuiper Belt. Finally, Planetary Society Director of Government Relations Jack Kiraly joins us with a major update on the ongoing fight to protect NASA science from devastating budget cuts. And don’t miss What’s Up with our Chief Scientist, Bruce Betts. We’re talking Arrokoth, the most distant Kuiper Belt object New Horizons visited after Pluto.

Very dense and podcastable. Cheap Astronomy finds there can never be too many podcasts about black holes.   Dear Cheap Astronomy – What are squeezars? Squeezars are stars that orbit supermassive black holes. Essentially they are stars on a slow death spiral into the black hole and the squeezing referred to is the tidal stretch being exerted upon them as the orbit closer and closer to the black hole's event horizon. That tidal stretching heats them up, a bit like how the moon of Io, orbiting close to Jupiter is the most volcanically active body in the Solar System. So they are unusually hot and they are also unusually fast.   Dear Cheap Astronomy – Do black holes float in water? Well, the internet says they do so it must be true. But let's unpack this a bit. The internet also says that if you compress the Earth down to marble size it will become a black hole. This is true in a hypothetical sense, but actually compressing the Earth down to marble size is pretty much impossible. You could use some kind of gargantuan press to start the process, but once the Earth becomes denser than the material the press surfaces are made of, the press becomes useless.    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 Chile, a powerful new telescope has just given a taster of what we can expect from it later this year, when it will be used to survey the cosmos over a ten-year period. In one image it revealed vast colourful gas and dust clouds swirling in a star-forming region 9,000 light years from the Earth. Housed in the Vera C Rubin Observatory, which sits on a mountain in the Chilean Andes, the telescope is designed to get giant images of the sky about one hundred times larger and quicker than any other existing telescope can achieve. It contains the world's most largest digital camera, the size of a large car. When the Legacy Survey of Space and Time begins towards the end of 2025, the camera will film the entire Southern hemisphere night sky for the next decade, every three days, repeating the process over and over. And it will focus on four areas: mapping changes in the skies or transient objects, the formation of the Milky Way, mapping the Solar System and understanding dark matter or how the universe formed. So, on this week's Inquiry, we're asking, ‘What will Chile's latest telescope tell us about the Universe?'Contributors: Catherine Heymans, Professor of Astrophysics, University of Edinburgh, Astronomer Royal for Scotland, UK Željko Ivezić, Director of Rubin Construction, Professor of Astronomy, University of Washington, USA Dr. Megan Schwamb, Planetary Astronomer, Reader, School of Mathematics and Physics, Queen's University, Belfast, Northern Ireland Dr. Burçin Mutlu-Pakdil, Observational Astronomer, Assistant Professor, Physics and Astronomy, Dartmouth College, New Hampshire, USAPresenter: Charmaine Cozier Producers: Louise Clarke and Jill Collins Researcher: Maeve Schaffer Editor: Tara McDermott Technical Producer: Craig Boardman Production Management Assistant: Liam Morrey Image Credit: Anadolu via Getty Images

This is an interview with me on The Last Easy Mile podcast with Josh Farahi. Video version: https://www.youtube.com/watch?v=lFRZvPc3U&ab_channel=TheLastEasyMilePodcast THE LAST EASY MILE: https://linktr.ee/TheLastEasyMilePodcast In this episode, Fraser Cain—founder of Universe Today and co-host of Astronomy Cast—shares why space still matters. From watching meteor showers with your kids to seeing Saturn's rings through binoculars in a city, Fraser offers practical ways to reconnect with awe. He reflects on raising science-minded kids, his love of tabletop RPGs, and how parents can create deeper imaginative experiences than screens can provide. We also talk about the James Webb Space Telescope, the Mars rovers, and the Vera Rubin Observatory, which will capture time-lapse images of the sky. Fraser warns against the growing distrust of experts, advocating for humility, critical thinking, and Carl Sagan's “baloney detection toolkit.”

From October 22, 2012. When an object is orbiting the Earth, it's really falling. The trick, described in the Hitchhiker's Guide to the Galaxy, is how to throw yourself at the ground and miss. There are several different kinds of orbits, and they are good for different reasons. From suborbital jumps to geostationary orbit, time to learn everything there is to know about going around and around and around.   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 explore the latest discoveries in lunar geology, the intriguing concept of dark dwarves, and the stunning features of the Carina Nebula.The Youngest Basaltic Lunar MeteoriteScientists have uncovered a 2.35 billion-year-old lunar meteorite, Northwest Africa 16286, which fills a significant gap in our understanding of the Moon's volcanic history. This meteorite, distinct in its chemical profile, suggests that volcanic activity on the Moon persisted longer than previously thought, unveiling new insights into its internal heat generation processes. Lead author Joshua Snape from the University of Manchester explains how this rare sample enhances our knowledge of lunar geology without the costs associated with space missions.Hypothetical Dark Dwarfs and Dark MatterA new study proposes the existence of hypothetical objects called dark dwarves, which could help unravel the mystery of dark matter—an invisible substance that constitutes approximately 80% of the universe's mass. Researchers suggest that these low-mass objects could interact with dark matter in ways that produce observable effects, providing a potential pathway to understand this elusive component of the cosmos. The study highlights the importance of identifying markers, such as lithium-7, to confirm the existence of dark dwarfs and advance our understanding of dark matter.Adaptive Optics and the Carina NebulaUsing adaptive optics, astronomers have achieved unprecedented clarity in imaging the western wall of the Carina Nebula, revealing intricate structures previously hidden by dust and gas. This breakthrough allows for a deeper investigation into star formation processes in this massive stellar nursery. The enhanced images showcase how massive young stars influence their surroundings and contribute to the cycle of stellar life, offering a glimpse into the conditions that may have shaped our own solar system.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of Cosmology and Astroparticle Physicshttps://www.journalofcosmology.com/Nature Journalhttps://www.nature.com/natureBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 00:49 04:51 09:17 15:16 17:08

Using parallax in real time to determine its position in space. How did they pull it off and what other interesting things can spacecraft do? Finding out in this interview.

https://www.youtube.com/watch?v=7x0RpGa_IXA From Jun 12, 2018. The Hubble Space Telescope has been in space for 28 years, producing some of the most beautiful and scientifically important images of the cosmos that humanity has ever taken. But let's face it, Hubble is getting old, and it probably won't be with us for too much longer.   NASA's James Webb Space Telescope is in the final stages of testing, and WFIRST (Nancy Grace Roman) is waiting in the wings. You'll be glad to know there are even more space telescopes in the works, a set of four powerful instruments in design right now, which will be part of the next Decadal Survey, and helping to answer the most fundamental questions about the cosmos.   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!

Can somebody really enforce any space treaties and do they make any sense? What's a better future, colonies on Mars or on giant rotating spaceships? What's India's space program been up to lately? And in Q&A+, would I take a one-way ticket to Mars?

https://www.youtube.com/watch?v=kaauzzrH4N8 From Oct 4, 2023.  Hosted by Tony Darnell. In recent years, scientists have made great strides in the search for extraterrestrial life. They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it. The search for life however, is a little more involved than finding planets, measuring their location and distance around the star and figuring out their location within a habitable zone.     Get all episodes: https://exoplanetradio.com Music by Gedoesium: 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!

When Asteroid hunters discover a new object it is given a score ranging from 0 which means it is likely to be a distant main belt asteroid up to 100 which means that it is likely to come near to us. Each newly discovered asteroid which receives a score of 65 or greater is posted on the Minor Planet Center's Near Earth Object Confirmation Page so that telescopes around the world can track it to estimate it's size as well as to refine our knowledge of it's orbit around the Sun. NASA feeds data on each new discovery into its Scout software system. Scout is designed to identify those objects which are most likely to make a close approach to Earth in the very near future. It's alert allows astronomers to access the new object's risk of impact as well as to study it before it fades into the distance. Fortunately, asteroid hunters have not found any dangerous impacting asteroids, however, Scout's rapid alert has enabled astronomers to measure the size, chemical composition, and rate of rotation for a number of close approaching asteroids. These data are extremely important to plan an effective response should an object be found to be on a collision course with planet Earth. For the vast majority of Earth approaching objects that asteroid hunters discover, additional observations make it less and less likely that an object will impact or even make a very close to approach to our home planet. Those few space rocks which have a tiny remote chance of coming very near to us are passed into NASA Sentry system which makes and keeps astronomers aware of nearby objects so that we do not lose track of them.

What if everything we think we know about stars is wrong? In this explosive conversation, mathematician Stephen Crothers dismantles the foundations of modern astrophysics, arguing that black holes, neutron stars, and gravitational waves are mathematical illusions built on misapplied thermodynamics and flawed logic. With the rigor of a forensic investigator, he exposes how simple errors in stellar models went unchecked for a century—raising unsettling questions about the integrity of science and the nature of the cosmos itself.PATREON https://www.patreon.com/c/demystifysciPARADIGM DRIFThttps://demystifysci.com/paradigm-drift-show00:00 Go!

* A Whole Lot Moore: Peter W. Moor, ThD is a Christian master metallurgist listed as "inventor" in patents held by U.S. Steel. Pete began speaking to Churches on Science and Evolution in 1970. His more recent work has been to help fund organizations that do scientific creation research and those who present that evidence to the public. * Aether or: ...relative nonsense. Hear a brief history, and then, not only criticisms of, but an alternate theory to Einstein's rather ridiculous postulates regarding time and space. Hear how Einstein not only dethroned Newtonian physics, but how his relativistic thinking has infected the minds of otherwise relatively smart creationists! * E-PLat - (The Simhony/EPOLA): RSR is suggesting a name for the E-PLat!! Hear how Menahem Simhony is the father of a scientifically satisfactory description of what "space" is likely made of. Originally called the EPOLA, for the "Electron/Positron Lattice," we're suggesting E-PLat to avoid confusion with a certain virus! You'll have to listen to all 4 parts of the interview to form your opinion on whether or not the EPOLA/E-PLat makes more sense to you than Einstein's "purely mathematical" description of a relativistic universe. * Deriving $10,000.00: ... and quite possibly a Nobel Prize! RSR and Dr. Moore are offering a prize of $10,000.00 to the first person to submit an acceptable technical derivation of the Gravitational Constatn "G" based on the Natural Physics and Structure of the Simhony/EPOLA Model of the Space Vaccuum.
