This is the THIRTEENTH season of the show! So we’re diving into stories about superstitions and luck. We’ll share the eerie tale of a 13-legged sea creature. We’ll talk about a hot new telescope that’s trying to look back 13 billion years ago to uncover the secrets of the universe. And we’ll talk about a squeaky superstition that involves a rat — as the tooth fairy. We speak to marine biologist Dr. Julian Evans, astrophysicist Dr. Jeyhan Kartaltepe, and biologist Dr. Philip Cox.  UPDATE 12/16/22: A previous version of this episode incorrectly conflated the units of pressure and force when comparing the bites of great white sharks and rats. The episode has been updated to make the distinction between pressure and force more clear.
