On Order



In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid, lyrical style, he discusses many topics from astrophysics and solar system science, to colonization of other worlds, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were 30 years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions.

Author Notes

A respected planetary scientist best known outside the field for his popularizations of astronomy, Carl Sagan was born in New York City on November 9, 1934. He attended the University of Chicago, where he received a B.A. in 1954, a B.S. in 1955, and a M.S. in 1956 in physics as well as a Ph.D. in 1960 in astronomy and astrophysics. He has several early scholarly achievements including the experimental demonstration of the synthesis of the energy-carrying molecule ATP (adenosine triphosphate) in primitive-earth experiments. Another was the proposal that the greenhouse effect explained the high temperature of the surface of Venus. He was also one of the driving forces behind the mission of the U.S. satellite Viking to the surface of Mars. He was part of a team that investigated the effects of nuclear war on the earth's climate - the "nuclear winter" scenario.

Sagan's role in developing the "Cosmos" series, one of the most successful series of any kind to be broadcast on the Public Broadcasting System, and his book The Dragons of Eden (1977) won the Pulitzer Prize in 1978. He also wrote the novel Contact, which was made into a movie starring Jodie Foster. He died from pneumonia on December 20, 1996.

Library Journal Review

This volume by the late Sagan won the John W. Campbell Memorial Award for best science book upon its initial publication (LJ 1/15/73). Sagan possessed a particular talent for taking something very complicated and explaining it in terms that the average person could easily understand. Humankind has long had a fascination bordering on obsession with the possibility of life beyond the boundaries of our own planet, and Sagan offers his take on extraterrestrial intelligence as well as life on Earth. This edition has been updated with a portrait of the author by his wife, plus a new introduction and an essay by science writer David Morrison assessing Sagan's theories, many of which have been proven true.
