Episode notes

David Wheeler: It's hard to imagine life evolving on the surface of a planet without an atmosphere. He says we're learning more that makes us wonder how important magnetic fields are in protecting Earth-like planets. "I'm less worried about the magnetic field part, which is the other thing that the question are asked"

Can there be life on planets without magnetic fields? Neil deGrasse Tyson and comedian Chuck Nice discuss exoplanets, extraterrestrials, and answer extraordinary questions from our fans with astrobiologist, David Grinspoon.
