The 365 Days of Astronomy

From March 8, 2017. In just a few months, NASA's Cassini spacecraft is going to die, crashing into the planet Saturn. Let's look back across the mission's history. What were the highlights? What did we learn?   Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com   Ask me my favorite object in the Solar System, especially to see through a telescope, and my answer is always the same: Saturn. Saturn is this crazy, ringed world, different than any other place we’ve ever seen. And in a small telescope, you can really see the...

The 365 Days of Astronomy

A podcast about rocks, big and small. Dear Cheap Astronomy – What’s Psyche really like? Psyche is an asteroid in the asteroid belt and apparently a very metal rich one, which makes it a prospecting target for budding asteroid miners. Pysche is also a spacecraft, launched on October 13, 2023. We’re recording this episode about one month after launch when it’s already over 15 million km from Earth – and its destination? Yep, Psyche – the asteroid.   Dear Cheap Astronomy – How is Mars Sample Return mission going? Here at Cheap Astronomy we’ve often said that landing on Mars...

The 365 Days of Astronomy

From April 14, 2025. Astronomers using the JWST have made direct observations of the black hole at the center of our galaxy: Sagittarius A*.  These observations are possible because the Webb Space Telescope can peer through the dust at the center of our galaxy using infrared light.  These observations surprised astronomers.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

The 365 Days of Astronomy

Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Feb 2, 2026. One long standing mystery in astronomy were the quasars. Incomprehensible energy blasting out of a point-like source, billions of light years away. We now know these are actively feeding supermassive black holes, which can turn off and on in a startlingly short period of time. Today: When black holes awaken! Our Universe is filled with sleeping monsters. And sometimes, whether we want it or not, they wake up hungry. In this episode, we take a look at the science behind how and why black holes of all sizes can go...

Today's 2 topics: - In the search for life on Mars, Europa, Titan, and elsewhere in the universe astro-biologists are scouring the Earth for creatures tough enough to flourish under really difficult conditions. So far the leading species are the Tardigrades commonly known as water bears or moss piglets. - Data are consistent with the hypothesis that the planet K2-18b is a Hycean planet with a warm liquid...

The 365 Days of Astronomy

From January 28, 2026. In this episode we look at highlights from the latest American Astronomical Society Meeting. An accidental theme came out: with each new telescope and each improved instrument we can look more closely at our Universe - we can and do learn more and understand more even about the things we thought we knew best. In this episode, Rubin Observatory brings rapidly rotating asteroids, and JWST peers at objects thriving in the first 2 billion years of our universe. Observatory after observatory brings us new science.   We've added a new way to donate to 365 Days of...

Ask me my favorite object in the Solar System, especially to see through a telescope, and my answer is always the same: Saturn. Saturn is this crazy, ringed world, different than any other place we’ve ever seen. And in a small telescope, you can really see the ball of the planet - you can see its rings.
