Those of you who know me very well, know that I am a huge fan of Carl Sagan. Skepticality, the official podcast of Skeptic magazine has a very nice interview with Ann Druyan, Sagan’s second wife and collaborator. The audio is a little weak, but the content more than makes up for it.
Another of my favorite people is Phil Plait from Bad Astronomy.com. Phil has a particularly wondrous post about what you can see in space from different points of view along the electromagnetic spectrum. Well worth a read.
