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 treasur...

https://www.youtube.com/watch?v=GhkGOIAhBWc Hosted by: Fraser Cain ( @frasercain ) and Dr. Pamela L. Gay ( @CosmoQuest ) Streamed live on Oct 3, 2026. Mission Tech Part 3. Instead of sending up an entire space station for every mission, you can just send up a tiny can filled with astronauts. But that takes docking. And today we're gonna talk about what it takes to connect two spacecraft together....

Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery.     New observations by a team of astronome...

Objective: objects! Hosted by Steve Nerlich. Dear Cheap Astronomy – How often does the solar system capture or eject things? The first evidence that stellar systems might eject things were observations of rogue planets knocked out of their systems due to gravitational interactions and now populating interstellar space. For every rogue planet knocked out its system there are likely thousands of sma...

Hosted by Loretta Cannon. Today's 'guest' is the planet Neptune.   I'm telling the story of the discovery of Neptune 180 years ago in September, 1846. It was initially identified using mathematics rather than a telescope. This is a story of missed opportunities, undisclosed data, a bit of professional rivalry, and a controversy that some still argue today.     H'ad astra historia is the official p...
