Like how the same basic stuff can make many different types of star, and planet and cookie, this episode brings a lot of familiar things together in new ways! Hanalore Gurling-Dunsmore!  Dr. James Sylvester! and our guest Zach Weinersmith! (Zach and his wife Kelly just wrote an amazing book!) we're going to talk about Supernovas (type 2). How a perfectly ordinary gigantic star can just one day decide to EXPLOOODDE. today's episode is amazing. It brings together a lot of things we have talked about in other episodes!
