Can Aliens Detect Us? with Bill Nye, Mike Massimino, and Eugene Mirman

A fan wants to how close an alien civilization would have to be to discover Earth, using the same level of technology we have here. Extraordinarily close, at least according to what guest host Bill Nye the Science Guy learned in his astronomy class taught by Carl Sagan. Enjoy this Cosmic Queries video clip featuring guest astronaut Mike Massimino and co-host Eugene Mirman. This "Behind the Scenes" video was shot during the recording of our episode, "Cosmic Queries with Bill Nye and Astro Mike."
