Cosmos: A Personal Voyage was the name of a thirteen part television series produced by Carl Sagan and Ann Druyan which was first broadcast in the Public Broadcasting Service in 1980 and featured a soundtrack by Vangelis. It won an Emmy and a Peabody award and has been since broadcast in 60 countries and seen by more than 500 million people, according to the NASA Office of Space Science.

Sagan's historical description of Hypatia of Alexandria and the burning of the Library of Alexandria has been criticized by historians who interpret the sources on Hypatia's life and the end of the library differently and who believe that Sagan should have made clear that there is a scholarly controversy on this issue. Other parts of Cosmos were controversial among the general public, though hardly among scientists, such as Sagan's straight-forward treatment of astrology as a pseudoscience and his equally straight-forward description of evolution as a fact, not just a theory.

Cosmos has long been unavailable after its initial release because of copyright issues with the included music, but has recently been re-released on DVD.

The thirteen parts are:

I: The Shores Of the Cosmos

Light years, galaxies, stars, planets: numbers and distances, where we are located (local group)

The Cosmic Calendar: from the beginning of the universe to the "arrival" of humans

II: One Voice In the Cosmic Fugue

Evolution through natural selection, from microbes to man
Speculation about life in Jupiter's clouds
Creation of the "molecules of life" in a laboratory experiment
The development of life on the Cosmic Calendar, and the Cambrian Explosion

III: The Harmony Of the Worlds

IV: Heaven and Hell

The Tunguska Event, the composition and origin of comets
Asteroids and impact craters
The planet Venus in fiction and fact
Venus as an example of the greenhouse effect

V: Blues For A Red Planet

VI: Travellers' Tales

The life and work of Christian Huygens and his contemporaries

VII: The Backbone of Night
