Great podcast, thanks for sharing
This is the best general astronomy podcast out there
I am possibly Fraser and Pamela’s biggest fan. These guys are the best!
5 Stars but these ad breaks whewww.
Usually ads don’t bother me, I just skip and move on but this show has more ads in its 30 minutes than multi hour shows I listen to, I’ve never listened to a podcast with more ads than this one.
