The Peabody and Emmy Award-winning PBS series Cosmos was written by astronomer/author Dr. Carl Sagan and his wife, Ann Druyan. Filmed in 40 locations over a two-year period, the programs explored the wonders of the universe, with explanations provided by Dr. Sagan. In this installment, Cosmos, Episode 3: Harmony of the Worlds, the life of Johannes Kepler, the first modern astronomer (who also wrote the first science fiction novel), is profiled. His influence on today's views on planetary motion is explored.
