Cosmos, Episode 7: Backbone of the Night on AllMovie

The earliest humans were perplexed by the stars and they attached meanings to them in an attempt to understand their significance. In this installment of the series Cosmos, the immensely popular PBS show hosted by astronomer/author Dr. Carl Sagan, viewers examine these early endeavors to comprehend the night sky. The stars were thought to be campfires in the heavens, and the great expanse of stars known as the Milky Way was the "backbone of the night." Dr. Sagan goes back to his childhood elementary school where the question "What are stars?" is the subject of discussion.
