Astronomy Cast Ep. 762: Science in Crisis - NASA’s New Budget
Release Date: 07/07/2025
Deep Astronomy - The Earth As An Exoplanet
The 365 Days of Astronomy
Hosted by Tony Darnell. From August 22, 2018. Are we alone? How unique is our Earth? Should the hunt for life beyond Earth uncover a multitude of habitable worlds and few (if any) inhabited ones, humanity would begin to understand just how lonely and fragile our situation is. On the other hand, if our hunt yields a true diversity of inhabited worlds, then we would learn something fundamental about the commonality of life in the cosmos. Like this content?

Astronomy Cast Ep. 10: Measuring Distance in the Universe
The 365 Days of Astronomy
From November 13, 2006. You hear distances all the time in astronomy. This star is 10 light-years away; that galaxy is 50 million light-years away; that Big Bang over there happened 13.7 billion years ago. But how did astronomers actually figure out how far away everything is? It’s not a single measuring stick. Instead, astronomers have built up a series of overlapping measuring tools (yes, we’re calling supernovae and variable stars “tools”), which take us from right around the corner to very ends of the Universe. Get out your ruler… no, the bigger one… never mind… just listen....

Travelers in the Night Eps. 803 & 804: Monster NEO & Tracie’s Solo
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From June & July 2024. Today's 2 topics: - Since larger space rocks are rare, it was surprising when my Catalina Sky Survey teammate Hannes Groller found a half mile diameter asteroid traveling through the constellation of Auriga. Fortunately on it’s current path 2024 JW1 can’t come closer than 53 lunar distances from us. Asteroid hunters will continue to track 2024 JW1 to make sure that it does not become a threat...

The Cosmic Savannah Ep. 72: Exploring New Horizons in Astronomy
The 365 Days of Astronomy
Hosted by Dr. Jacinta Delhaize, Dr. Tshiamiso Makwela & Dr. Daniel Cunnama. From June 19, 2024. Season 6. In this episode of The Cosmic Savannah, our hosts chat with Dr. Rojovola Zara-Nomena Randriamanakoto from the South African Astronomical Observatory about her transformative journey from Madagascar to becoming an instrumental figure in astronomy, advocating for women in STEM, and her research on star clusters and colliding galaxies. Dr. Zara Randriamanakoto is an influential astronomer from Madagascar working at the South African Astronomical Observatory. She moved to South...

UNAWE Space Scoop - What Did Our Solar System Look Like as a Baby?
The 365 Days of Astronomy
Hosted by Richard Drumm, your editor! Planets don’t just pop out of nowhere, fully formed and ready for astronomers to study. First, they begin as tiny little specks of dust, forming inside the clouds of gas around baby stars, which are known as protoplanetary discs. These dusty specks condense from the hottest parts of the cloud, kinda like the way raindrops form inside rainclouds. Over time, the specks of dust collide and stick together, forming rocky pebbles. When enough of these pebbles clump together, they can collapse under their own weight to form asteroid-sized...

Cheap Astronomy Ep. 121: Black Holes Yet Again!
The 365 Days of Astronomy
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...

Ask A Spaceman Ep. 252: Why Can’t We Get Free Energy from the Vacuum?
The 365 Days of Astronomy
Hosted by Dr. Paul M. Sutter. Why does the vacuum of spacetime have energy? How much energy does it have? What prevents us from using it to do anything useful? I discuss these questions and more in today’s Ask a Spaceman! Support the show: All episodes: Watch on YouTube: Read a book: Keep those questions about space, science, astronomy, astrophysics, physics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE! Big thanks to my top Patreon supporters this month: Justin G, Chris L, Alberto M, Duncan M, Corey D, Michael P, Naila, Sam R, John...

Astronomy Cast Ep. 277: Orbit
The 365 Days of Astronomy
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.

Travelers in the Night Eps. 801 & 802: Jacqui’s PHA & Bok Comet
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From June 2024. Today's 2 topics: - My Catalina Sky Survey teammate Jacqueline Fazekas was asteroid hunting with our small but mighty Schmidt telescope on Mt. Bigelow, Arizona when she spotted and then reported a bright moving point of light in the night sky to the Minor Planet Center. Given the rate of human caused climate change one has to wonder about the state of our planet in January of 2163 when 2024 ER is predicted to...

Hosted by: Fraser Cain and Dr. Pamela L. Gay
Normally we try to end the season on a high note. But there’s unfolding news that we just HAVE to cover before we leave you for the summer. NASA’s new budget is here, and it’s 25% smaller. We’ll cover what the changes are and try to understand the implications. It's a bad decade to be a researcher. We're going to look at why, and what US cuts will mean for the world.
