This installment of the acclaimed PBS series Cosmos focuses on the possibility of other intelligences in the universe, and the complexities that arise if communication is attempted. Dr. Carl Sagan, well-known astronomer and author, spent a large part of his life on a quest to find other lifeforms. In Cosmos, Episode 12: Encyclopedia Galactica, he takes the viewer to Egypt to puzzle over hieroglyphics, then to Arecibo Observatory, where the largest radio telescope in the world resides. He then invites the audience to imagine what another civilization in space would be like.
