[Volume] XII : Scrutinizes a notorious UFO incident and the unsubstantiated theories of von Daniken. Explores the probable nature of intelligent civilizations in the universe and the means by which contact might be made. Notes that the "Rosetta Stone" for interstellar communication is likely to involve the laws of physics. At the Arecibo Observatory in Puerto Rico, Dr. Sagan programs the world's largest radio telescope to listen for signs of life on a distant star. [Volume] XIII : Dr. Carl Sagan reviews the ideas of cosmic evolution, the methodology of the scientific approach, and the limitations of our perceptions about the cosmos. Dr. Sagan also gives some cautionary warnings about the types of futures we face as a species and as a planet.
