  • 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!
