Carl Sagan was an accomplished astronomer and cosmologist, and is well-known and loved for his work as a science popularizer and communicator. He contributed to the body of work that explains the greenhouse effect and its role in the temperature of Venus. He helped lend credibility to the search for extraterrestrial life, and produced work with CETI - Communication with Extraterrestrial Intelligence.

Dr. Sagan was the presenter and co-writer of the inspirational television series, Cosmos. He was a skeptic and educator of critical thinking, and his 1995 book The Demon-Haunted World: Science as a Candle in the Dark has helped laypeople to gain a greater understanding of the scientific method and rational inquiry.

November 14th is Carl Sagan Day and to celebrate we'll discuss Carl Sagan's contributions and achievements. Travis Peterson is an organizer for the Minnesota Skeptics and a fan of Carl Sagan's works and legacy. Join us on Sunday to talk about space, critical thought, Cosmos, Contact and "bilions and billions" of other topics (okay, not quite that many).
