Taking you on a facts-based journey through the cosmos
Launched in September 2006, the Astronomy Cast podcast has spent 19 years bringing you what we know and how we know it about this Universe we share. Fraser Cain, the publisher of Universe Today, brings the questions and curiosity of an astronomy lover to every episode. Bringing the answers is astronomer Dr. Pamela L Gay, the director of CosmoQuest at PSI.
