Cheap Astronomy - Dear CA Ep. 129: More Rocks
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...

Deep Astronomy - Discoveries of Webb Space Telescope Ep 3: The Flares of Sagittarius A*, Our Galaxy's Black Hole
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.

Astronomy Cast Ep. 781: Awakening Black Holes
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...

EVSN - JWST Makes Sense of the Early Universe
The 365 Days of Astronomy
From January 28, 2026. In this episode we look at highlights from the latest American Astronomical Society Meeting.

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...

info_outlineFrom April 27, 2021.
The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
