Myan Bryan ,

The Dan Carlin of science podcasts

He goes into the topics in depth and doesn’t leave you feeling like he glossed over it because he didn’t want to scare you. He hits you with the real thing and it’s addictive. Going through the back catalog now and loving every minute. Thank you!

Fedrog ,

Amazingly insightful!

Awesome how Dr. Sutter is able to explain some of the most difficult concepts in an amazingly simple way. Just listening to just a few episodes won’t do justice. Listening to as many as I can has made a huge difference in expanding my breadth of astronomy knowledge. Thank you and please keep doing this forever!

Delysid ,

A real education

A lot of astronomy podcasts are kind of news-driven, going over the latest discoveries & major sky events, or listener questions driven. This one does some of that, but mainly it gives the background science and explains in detail important foundational concepts, allowing you to make sense of those other podcasts.
