Cheap Astronomy - Dear CA #141: Sorting The Universe
The 365 Days of Astronomy
Hosted by Steve Nerlich. A podcast of sorts… Cheap Astronomy gets organized! Dear Cheap Astronomy – How are asteroids organized? The large majority of asteroids in the solar system are in the asteroid belt between mars and Jupiter. There are maybe 1-2 million that are more than a kilometer in diameter and millions more that are smaller than that. Nonetheless there’s a huge amount of space between mars and Jupiter so it’s nothing like that bit in the Empire strikes back. If you stood one asteroid is unlikely you’d be able to see another one and the odds of successfully navigating it...

Ask A Spaceman Ep. 282: What Happens When You Shine a Light on Nothing?
The 365 Days of Astronomy
Light Up Empty Space! Hosted by Dr. Paul M. Sutter. How does the vacuum interact with light? Is it possible to use light to create something from nothing? And is “birefringence” a real word? 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, Corey D,...

Astronomy Cast Ep. 805: Mission Tech Series - Gyroscopes & Servos
The 365 Days of Astronomy
Spinney things! Streamed live 18 Oct 2026. Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Our journey through space exploration technology continues! Today we look at the things that spin: gyros, reaction wheels, servos. Newton’s laws are large and in charge today as spinning has a very useful benefit when you’re in weightlessness! Today we are going to understand the nemesis of space exploration missions everywhere, get to the bottom of this, how these things works, why they fail, and maybe what’s being done about it, or maybe not! We've added a new way to donate to...

Travelers in the Night Eps. 385 & 386: New Aten & Silent ET
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 April 2026. Today's 2 topics: - Recently my Catalina Sky Survey teammates Carson Fuls and Greg Lenoard discovered an Aten asteroid which orbits the Sun once every 272 days and on a path that crosses the orbits of Venus and Earth a number of times each year. Atens account for only about 6% of the Earth approaching asteroids that asteroid hunters discover. They are relatively dim and difficult to discover because they...

AstroMan - G Is For Galileo
The 365 Days of Astronomy
Galileo turned the telescope skyward and transformed astronomy, revealing lunar mountains, sunspots, Jupiter’s moons, and a Universe far larger than imagined. “ASTROMAN: the Dark Sky Guardian” is a podcast channel that aims to explore popular science in multiple disciplines and research on interdisciplinary approaches, such as sustainability, dark-sky protection, astrophotography, space exploration, astronomy innovation, inclusive science communication, and STEAM Education by integrating science and arts. Exodus Chun-Long Sit, also known as the ASTROMAN, is a transmedia...

Actual Astronomy - Saturn at Opposition
The 365 Days of Astronomy
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. In this episode, we cover key visual observing highlights for Saturn, including prominent features like the Equatorial Band and Equatorial Zone visible in amateur telescope. We also look at historical transient phenomena, such as the massive, planet-encircling "Great White Spots" that erupt in the northern hemisphere roughly once every Saturnian year. Alexio wrote: Hi Chris and Shane, I saw Saturn in your...

EVSN - Luminous Kilonova Challenges Gamma-ray Burst Theories
The 365 Days of Astronomy
From November 2020. The brightest kilonova ever was detected and challenges current gamma-ray burst models. Plus, the history of water on both Venus and Mars, how radioactive elements may help habitability, and a little-known mass extinction event here on Earth. But wait! There’s more… new images of the Perseus Cluster, a recaptured 1960s rocket booster, the shortest measurement of time, a treasure trove of copies of Principia, and SpaceX is certified to launch Crew-1 this weekend. Perseus Cluster pix: We've added a new way to donate to 365 Days of Astronomy to support...

Guide To Space - Universe Today News: NASA Selects GIMLI to Search the Marius Lunar Pit for a Potential Lunar Base Site
The 365 Days of Astronomy
Recorded by our editor, Richard Drumm. Written by Matthew Williams. Lava tubes on the Moon and Mars are some of the most fascinating and useful places we could explore. These are natural tunnels below the surface that could protect astronauts from radiation, provide a constant temperature, and could even be sealed off as a place for a habitat. Now, a new mission is under development called GIMLI that could use ground-penetrating radar to scan beneath the surface and map out the extent of a lunar cave network. We've added a new way to donate to 365 Days of Astronomy to support editing,...

Awesome Astronomy - Extra: The Hubble Tuning Fork & Citizen Science
The 365 Days of Astronomy
Paul Hill hosts solo! Damien Phillips, John Wildridge and Dustin Ruoff produce. In this podcast extra episode we talk to Dr. Karen Masters, Associate Professor of Physics and Astronomy at Haverford College, Pennsylvania about The Hubble Tuning Fork and Galaxy classification. But it’s not only about that canonized galaxy classification system, it’s also about how citizen science – astronomy done by absolutely anybody from their homes – can and does change the accepted wisdom and advance science.

From December 2023.
Today's 2 topics:
- During a six hour period three small space rocks passed through the Earth-Moon system. At discovery 2023 TO4 was in Pegasus, 2023 TD7 was in Aries , and 2023 TQ3 was in Eradanus.
- Every year a significant number of comets and asteroids are discovered by amateur astronomers with modest equipment.Their reward is satisfaction and the right to name their discovery.
