Today on the Signorile Show

Guest / 4:30pm EST - We look up at it everyday. It's been the key to life on the planet. It has influenced religions and folk lore for centuries. That's right, I am talking about the sun. Bob Berman is the author of The Sun's Heartbeat: And Other Stories From The Life Of The Star That Powers Our Planet and joins us this afternoon to talk about his book, which is a biographical look at the life of the sun.
