Podcasts about Astronomy

From September 10, 2007. Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) This is a very different episode of Astronomy Cast. As we mentioned last week, Pamela recently attended the Dragon*Con science fiction convention in Atlanta, Georgia. While she was there, she participated in a special live edition of Astronomy Cast with special guest Dr. Kevin Frazier. Kevin is a NASA scientist, and the science consultant for the TV shows Battlestar Galactica and Eureka. He and Pamela work through physics and astronomy in popular science fiction. What they get right, and what they get wrong... so very wrong.   Role of Science Consultants in Media: Dr. Grazier shares insights into his work as a science consultant, emphasizing the importance of scientific accuracy in storytelling and how it enhances narrative credibility. Analysis of Battlestar Galactica and Eureka: The conversation explores specific examples from these series, highlighting where scientific principles are accurately depicted and where creative liberties are taken. Common Misconceptions in Sci-Fi: They address prevalent scientific inaccuracies in science fiction, such as sound in space and unrealistic space travel mechanics, and discuss their impact on public understanding of science. Balancing Science and Storytelling: The discussion delves into the challenges writers face in integrating complex scientific concepts into engaging narratives without overwhelming the audience. Audience Interaction: Recorded live at Dragon*Con, the episode features questions from the audience, providing additional perspectives and inquiries about science in media.   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 January & February 2026. Today's 2 topics: - On Earth, human life is enabled by plants which provide us with calories, vitamins, fuel, medicines, and oxygen to breathe. In addition, recent scientific studies indicate that plant cultivation reduces anxiety and depression and has a positive influence on diabetes, heart disease, obesity, and longevity. Perhaps this is the reason that 80% of the cultivated plant species on planet Earth are not used for any food related purpose. On long duration space missions astronauts live in close quarters isolated from the natural world where the basic activities like eating, sleeping, and attending to bodily functions are difficult and stress producing.    - On it's gravitational leash, Earth's pet space rock, 2016 HO3, accompanies us at a distance of between 38 and 100 times the Moon's distance from Earth as we both travel about the Sun. As this tiny asteroid orbits the Sun it spends about half of its time inside the Earth's orbit where it moves faster and passes ahead of us and the other half of its yearly path outside of our orbit which causes it to lag behind our home planet. Since its discovery little has been known about Earth's pet space rock leaving some to speculate that perhaps it is an old rocket booster or other piece of space junk.   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!

Space Nuts: Spanish Eclipse, Nancy Grace Roman Launch, Cloud Nine, and Venus's Mysterious CloudsAndrew Dunkley and Professor Fred Watson cover four big astronomy stories in this episode, from Fred's trip to view a sunset eclipse in Spain to the launch of the Nancy Grace Roman Space Telescope. They also unpack a starless dwarf galaxy called Cloud Nine and a new way of thinking about the strange dark material in Venus's clouds.Guests and speakersAndrew Dunkley - Host, frames the news, asks listener questions, and guides the discussion.Professor Fred Watson - Astronomer at large, explains the eclipse, the Roman telescope, Cloud Nine, and Venus's clouds.Key topicsIn this episode, Fred recounts the Spanish eclipse expeditionThe eclipse was only 9 degrees above the western horizon at totality, making the viewing conditions unusually challenging.He and Marnie led a 16-person tour through France, Spain, and Switzerland before settling near Santander in northern Spain.They staked out a viewing site 2 kilometers from the hotel, set up a gazebo, and had to tie it down to a car to keep it from blowing away.The weather looked threatening, but a hole opened in the cloud just before totality, giving them a clear view of the corona.Fred described the yellowish corona, pink hydrogen clouds, and the crowd of around 2,000 people.We discuss the Nancy Grace Roman Space Telescope launchAndrew watched the launch live after being nudged by his own brain at the right moment.Fred noted the launch was flawless, with 27 Merlin motors firing.The telescope is headed for the L2 Lagrange point, about 1.5 million kilometers away.Roman is a 2.4-meter Hubble-class telescope but with 100 times the field of view.Its wide-angle infrared design should enable major surveys of dark matter, dark energy, and exoplanets via its coronagraph.Fred explains why Cloud Nine mattersCloud Nine is described as a starless dwarf galaxy about 14 million light years away.It lies near Messier 94 and was studied using the Gran Telescopio Canarias and its Hypercam instrument.The deep exposure was 2.36 hours, yet the team found no convincing stellar population.Fred says theory suggests the gas may be too hot to cool and collapse into stars because of the ultraviolet background radiation after reionization.He says Cloud Nine may be the first strong example of a galaxy predicted by standard cosmology but never before clearly identified.Venus's clouds are still puzzling astronomersFred explains that Venus appears yellowish because we see the top of its cloud layer, especially in visible light.In ultraviolet, Venus shows dramatic global cloud patterns caused by an as-yet unidentified absorber.The new study uses radiative transfer modeling to constrain what the unknown absorber could be.The team compares Venus's cloud droplets to cigarette smoke, tiny particles that look light-colored when dispersed but could become dark sludge in bulk.The result suggests the absorber must be very efficient, very concentrated, or both, but it is not being claimed as evidence of life.Become a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From January, 2026. Today's 2 topics: - 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-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.   - 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 can theoretically 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 its 926 day orbital path around the Sun, estimate its size, and give it the name 2017 TH5.    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!

Looking into the sky at night with radio eyes you would not see the points of starlight forming the constellations instead you would see a very bright, colorful and wildly changing scene. In a desert valley near the Great Basin National Park Caltech is building the world's largest radio telescope called the Deep Synoptic Array or DSA for short.

Space Nuts: Moon impact, Roman Observatory launch, and Neptune's odd moonsAndrew Dunkley is joined by Professor Jonti Horner, Professor of Astrophysics at the University of Southern Queensland, for a wide-ranging astronomy update. They cover SpaceX's out-of-control rocket body hitting the Moon, the imminent launch of the Nancy Grace Roman Observatory, and a new result that may explain the strange origin of some of Neptune's moons.We discuss why lunar impacts matter far beyond the Moon itself, how Roman will study exoplanets and dark energy, and why clay minerals on Neptune's small moons are such a big clue about a violent early solar system.Key topicsSpaceX's rocket body impacted the Moon after being left in a long, uncontrolled orbitWhy lunar impacts are a real concern for future habitats, infrastructure, and Apollo heritage sitesThe sheer scale of human-made objects that have already hit or landed on the MoonElon Musk's vision for lunar factories, rail-gun launches, and large-scale off-Earth manufacturingWhy the same company could end up both creating the risk and needing to solve itThe Nancy Grace Roman Observatory launching around 9 months ahead of scheduleRoman's 2.4 metre mirror, 300 megapixel wide-field camera, and hydrazine-fueled journey to L2How Roman will study dark energy, gravitational lensing, exoplanets, and free-floating planetsNew James Webb observations of Neptune's moons showing clay-type minerals on Larissa and GalateaWhy those clays suggest a much older, more violent system shaped by Triton's capture and moon-to-moon collisionsTimestamps:00:00 - Studio prep, muting phones, and getting ready to record01:53 - Episode intro: SpaceX lunar impact, Roman Observatory, and Neptune moons03:00 - Jonti Horner joins the show04:26 - SpaceX rocket body crashes into the Moon07:03 - Predicted impact plume and expected crater size08:54 - Korean spacecraft Danuri captures post-impact images10:19 - Why Moon impacts matter for future lunar bases11:47 - Protecting Apollo landing sites and lunar archaeology12:15 - More than 3,000 human-made objects have hit the Moon14:32 - Law, responsibility, and the problem of cleanup beyond Earth16:07 - Musk's plans for Moon factories and Starlink-style expansion18:12 - Rail guns, Optimus robots, and scaling lunar industry19:34 - SpaceX's own industry could be threatened by its own debris21:24 - Balancing commercial benefits and environmental costs23:46 - The Nancy Grace Roman Observatory launch approaches26:03 - Roman's orbit, hydrazine fuel, and five-year mission plan27:57 - From WFIRST to Roman: how the telescope evolved29:23 - Roman's mirror, 300 megapixel camera, and survey power30:14 - Exoplanets, microlensing, and the coronagraph33:29 - Roman's launch status and the excitement ahead34:17 - Neptune's moons and the role of TritonBecome a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.

https://www.youtube.com/watch?v=Rx1276dpHe4 From Jan 14, 2020. Hosted by: Fraser Cain (@frasercain) Once again, at the AAS Meeting in Hawaii, I got a chance to sit down with another astronomer to talk about their research. This time it was Dr. David Kipping from Columbia University's Cool World's Lab. We talked about how easy it'll be for aliens to know our planet is inhabited, and some ways we might be able to hide the evidence of our existence.

Roman will test new technologies for space-based planet hunting.

After decades of development, the Nancy Grace Roman Space Telescope is preparing to launch. Once in orbit, Roman will conduct the widest surveys of the universe ever attempted, probing the nature of dark energy, discovering thousands of new exoplanets, and capturing images of billions of galaxies. In this episode, we sit down with Julie McEnery, senior project scientist for Roman at NASA's Goddard Space Flight Center, and Jason Rhodes, project scientist for Roman at NASA’s Jet Propulsion Laboratory, to explore what the telescope will reveal and how scientists around the world will be able to access and work with its data. Plus, in What's Up, we look at Roman's coronagraph and what it will take for the Habitable Worlds Observatory to push that technology far enough to image Earth-like worlds around Sun-like stars.

Some place in space. Hosted by Steve Nerlich. Dear Cheap Astronomy – What is the role of AI in space? AI simulates human decision-making and finds most practical usage in the sorting and analysing of various kinds of data. So. you can feed an AI program pictures of galaxies and the classifications they fit into and then the AI can then identify and classify new ones that you feed it. It's kind of like how Galaxy Zoo used to work, except with Galaxy Zoo it was actual crowd-sourced people that did the work.   Dear Cheap Astronomy – What will space warfare look like? We've previously discussed on this podcast that fighting a war from space is probably a bad idea. You might conceivably drop a bomb from orbit, but once you've identified yourself as an enemy it's pretty easy to take you out from the ground. You may be able to dodge a few missiles at the start, but once you're out of maneuvering fuel you'll be stuck in a straight-line orbit and hence a sitting duck.   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!

Although no comet nucleus impact on the Earth has been conclusively identified, there is some evidence that suggests the 1908 Tunguska event in Russia, which knocked down trees over a 770 square mile area, could have been caused by a fragment of Comet Encke. However there is no doubt that the Earth's collision with dust and small debris left trailing from comets produces some of the meteor showers we enjoy so much.

When the James Webb Space Telescope started sending back images in 2022, something mysterious appeared: little red dots, speckled across the sky. They didn't look like any known celestial objects, and astronomers began racing to figure out what they were. There was a lot of hot debate, but researchers are making progress—the dots appear to be black holes, but black holes like we've never seen them before. In a recent study, astrophysicist Rohan Naidu and his team looked into one little red dot with the catchy name of MoM-BH*-1 and concluded it was a new cosmic category called a black hole star. Guest: Dr. Rohan Naidu is an assistant professor at the Institute for Astronomy at the University of Hawaiʻi.

From August 11, 2008. Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) Last week we talked about rockets. How they work, how they go BOOM!, their limitations. And this week we're going to look at the future of propulsion systems. From the ion engines that are already working to explore the Solar System to the prototype solar sails to futuristic technologies like magnetic sails, and bussard ramjets. This is how we'll travel to other stars.   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 December 2025 & January 2026. Today's 2 topics: - Many people in our modern world rarely if ever experience night vision. To achieve this interesting state of sensory awareness you cannot look at your cell phone or any other source of bright light for 30 to 45 minutes. Your night vision comes about over time because the rod sensors in the retina of your eye undergo a chemical change when they are placed in total darkness. The process starts immediately but takes 20 to 30 minutes to get 80% of maximum sensitivity. The night vision process can be reversed in seconds by exposure to a bright light. In its most sensitive state your eye can function with a billion times less light than is present in strong sunlight enabling you to see a candle flame from 1.6 miles away.   - In November of 2006, University of Arizona's Spacewatch astronomers on Kitt Peak discovered a faint moving point of light in the night sky which appeared to be a garden variety main belt asteroid orbiting the Sun between Mars and Jupiter. The Minor Planet Center calculated it's orbit and gave it the name 2006 VW139. Five years later when it again moved closest to the Sun the Pan-STARRS group in Hawaii discovered that 2006 VW139 is surrounded by a gas cloud like a comet and it was given a comet designation, 288P.    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!

Will we change or terraform Mars to better suit humans? Or are we more likely to change ourselves to better fit the red planet? How far can evolution take us in these new and exotic environments? These and many other fascinating questions are at the heart of Rice University professor Scott Solomon’s great book, “Becoming Martian”.
