In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

Future generations will look back on our epoch as the time when the human race broke into a radically new frontier - space. In Pale Blue Dot Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies Beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor a luxury, insist Sagan, but a rather a necessary condition for the survival of the human race.
