  • Absolutely fantastic show with great great host

    This is my first ever podcast that I listened to so P. Sotter opened doors to two amazing worlds of Astronomy and podcasting for me at the same time - forever grateful for hours of fun and educational content that he has put out to the world. Stay awesome Paul!

  • Educational and fun to listen to!

    When did I start to like and even remotely understand Science and Astrophysics?! What happened?!! Oh ya, Paul happened! lol! It doesn’t matter how much you know if you cannot explain it to people in a way they can understand. Paul does an incredible job of explaining Astrophysics, whether your a novice or veteran. Thank you for taking the time to make this podcast!
