Cosmos (Carl Sagan)

Together with Ken Burns The Civil War, Carl Sagan’s Cosmos is probably the most widely seen television documentary of all time, and one of the most influential. Throughout 13 hour-long episodes, famed Astrophysicist and science communicator Carl Sagan takes you through every aspect of our universe, from the big bang, to Einstein’s theory of relativity, to the emergence of life.  

The Emmy and Peabody Award-winning series was first broadcast in 1980, and featured groundbreaking special effects that allowed Sagan to walk through environments that were really miniatures, all while delivering his precise narration. What comes across is his sincere awe and fascination with the scale and machinations of the universe, and how insignificant we all are by comparison. He also has the real gift of communicating complex physics concepts in understandable terms, such as in episode 10 “The Edge of Forever,” which has him explaining the shape of the Universe by describing a two dimensional world from the point of view of our 3D existence.

It’s is fascinating, engrossing stuff, and even when Sagan’s goes over the top with his grand hyperbole, you never get the sense he is any less than sincere. A landmark in documentary television and the popularization of science.


Being a 30-year old television production shot on a mixture of film and video, the video quality is about what is to be expected. The packaging reportedly claims it’s been “digitally remastered and restored,” and while often that’s mere marketing hooplah, here the result is an image that is surprisingly clean if not very sharp. There’s little definition in the images, plenty of edge artefacts and little vibrancy in colour, but the content is so good these flaws are easily overlooked. The soundtrack is a just fine Dolby 2.0.

Special Features

With so much core content and with Sagan’s death in 1996, there’s little in the way of extras. There are short updates from Sagan for a number of the episodes, recorded a decade following the series in 1990, which give a brief overview of the then recent scientific and technological advances. As much of the content is still valid today, thirty years later, these updates feel not entirely necessary but are still interesting.

Otherwise, Disc One opens with a mellow introduction to the series from series co-writer (and Sagan’s widow), Ann Druyan, and the last disc features the “Fotografica Galactica”, a nine minute video of CGI renditions of our solar system and real images from the Hubble Space Telescope and the Cassini-Huygens mission to Saturn and Titan.

Full Episode List

Episode 1 – The Shores of the Cosmic Ocean
At the beginning of this cosmic journey across space and time, Dr. Carl Sagan takes us to the edge of the universe aboard a spaceship of the imagination. Through beautiful special effects, we witness quasars, exploding galaxies, star clusters, supernovas and pulsars. Returning to our solar system, we enter a re-creation of the Alexandrian Library, the seat of learning on Earth 2,000 years ago.

Episode 2 – 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.

Episode 3 – The Harmony of the Worlds
This episode is a historical re-creation of the life of Johannes Kepler, the last scientific astrologer, the first modern astronomer and the author of the first science fiction novel. Kepler provided the insight into how the moon and the planets move in their orbits and ultimately how to journey to them. It's also a story about the scientific process of discovery, and how the search for truth is never easy but always worthwhile.

Episode 4 – Heaven and Hell
A descent through the hellish atmosphere of Venus to explore its broiling surface serves as a warning to our world about the possible consequences of the increasing greenhouse effect. Then Dr. Sagan leads us on a tour of our solar system to see how other heavenly bodies have suffered from various cosmic catastrophes.

Episode 5 – 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.

Episode 6 – Travelers' 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.

Episode 7 – The Backbone of Night
Humans once thought the stars were campfires in the sky and the Milky Way "the backbone of night." In this fascinating segment Dr. Sagan takes us back to ancient Greece, when the basic question "what are the stars?" was first asked. He visits the Brooklyn elementary school of his childhood, where this same question is still on students' minds.

Episode 8 – Travels 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.

Episode 9 –The Lives of the Stars
Using computer animation and amazing astronomical art, Dr. Sagan shows how stars are born, live, die and sometimes collapse to form neutron stars or black holes. We then journey into the future to witness "the last perfect day on Earth," 5 billion years from now, after which the sun will engulf our planet in the fires of its death throes.

Episode 10 – 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.

Episode 11 – The Persistence of Memory
The brain is the focus of this fascinating portion of our journey as Dr. Sagan examines another of the intelligent creatures with whom we share the planet Earth — whales. Then we wind through the maze of the human brain to witness the architecture of thought. We see how genes, brains and books store the information necessary for human survival.

Episode 12 – Encyclopedia Galactica
Are there alien intelligences? How could we communicate with them? What about UFOs? The answers to these questions take us to Egypt to decode ancient hieroglyphics, to the largest radio telescope on Earth and, in the Spaceship of the Imagination, to visit other civilizations in space. Dr. Sagan answers questions such as: "What is the life span of a planetary civilization?" and "Will we one day hook up with a network of civilizations in the Milky Way galaxy?"

Episode 13 – 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.
