New StarTalk episode out now on space volcanoes!

I’m so excited that my new StarTalk episode is out on YouTube (and as a podcast). This is my 12th StarTalk appearance!! I can’t believe it myself but there you go. It’s certainly nice to be invited back so often, especially when I get to chat about space volcanoes! It was lots of fun chatting with astrophysicist Neil deGrasse Tyson and comedian Matt Kirshen and answering questions sent in by StarTalk fans.
