At the beginning of this cosmic journey across space and time, Dr. Carl Sagan takes us to the edge of the universe aboard a spaceship of the imagination. Through beautiful special effects, we witness quasars, exploding galaxies, star clusters, supernovas and pulsars. Returning to our solar system, we enter a re-creation of the Alexandrian Library, the seat of learning on Earth 2,000 years ago.
