Cosmos: A Personal Voyage

S01E06

Travellers' Tales

Dr. Sagan compares the exhilaration of 17th-century Dutch explorers who ventured in sailing ships halfway around our planet in their quest for wealth and knowledge to an inside view of the excitement around Voyager's expeditions to Jupiter and Saturn. The newly acquired treasures of our present golden age of exploration are the focus of this episode.

S01E10

The Edge of Forever

Dr. Sagan leads us on some awesome trips — to a time when galaxies were beginning to form, to India to explore the infinite cycles of Hindu cosmology, and to show how humans of this century discovered the expanding universe and its origin in the big bang. He disappears down a black hole and reappears in New Mexico to show us an array of 17 telescopes probing the farthest reaches of space.

S01E08

Journeys in Space and Time

A voyage to see how star patterns change over millions of years is followed by a journey to the planets of other stars, and a look at the possibility of time travel. This takes us to Italy, where a young Albert Einstein first wondered what it would be like to ride on a beam of light.

S01E05

Blues for a Red Planet

Is there life on Mars? Dr. Sagan takes viewers on a tour of the red planet first through the eyes of science fiction authors, and then through the unblinking eyes of two Viking spacecrafts that have sent thousands of pictures of the stunning Martian landscape back to Earth since 1976. Though based on older Mars missions, Sagan's analysis still holds true.

One Voice in the Cosmic Fugue

Dr. Sagan's cosmic calendar makes the history of the universe understandable and frames the origin of the Earth and the evolution of life. We see the evolutionary process unfold, from microbes to humans. Our understanding of how life developed on Earth enables us to venture to other worlds for imaginative speculations on what forms life might take elsewhere.

S01E13

Who Speaks for Earth?

Through the use of special effects we retrace the 15-billion-year journey from the big bang to the present. We also hear the tragic story of the martyrdom of Hypatia, the woman scientist of ancient Alexandria. This is the famous episode on nuclear war in which Dr. Sagan argues that our responsibility for survival is owed not just to ourselves, but also to the cosmos, ancient and vast, from which we spring.
