Bullseye With Jesse Thorn

John Hodgman guest hosts this interview with astrophysicist Dr. Neil deGrasse Tyson. Dr. Tyson is the director of the Hayden Planetarium, but the layperson likely knows him as the host of Star Talk Radio and the PBS program Nova ScienceNOW. His upcoming projects include a new version of the TV series Cosmos — originally hosted by Carl Sagan — and a new book titled Space Chronicles. He talks to us about how money for space exploration stacks up to other spending, his personal space travel dreams, and more.
