Pale Blue Dot: A Vision of the Human Future in Space

By Carl Sagan

Categories: Science & Math

Carl Sagan reflects on humanity's place in the cosmos, inspired by the Voyager 1 photograph of Earth as a tiny dot. Sagan describes the exploration of the solar system, from the planets and their moons to the search for life, and argues that humans must eventually settle other worlds to survive. He also reflects on how the cosmic view should humble us. The book was published in 1994.
