Product Description

Astronomer Carl Sagan's landmark 13-part science series takes you on an awe-inspiring cosmic journey to the edge of the Universe and back aboard the spaceship of the imagination. Topics covered include: the 15-billion year history of the Universe; the evolution of life on Earth and what forms life might take on other worlds; Johannes Kepler, the first modern astronomer; the hellish atmosphere of Venus and the threat of the Greenhouse Effect on Earth; the search for life on Mars; the 17th century exploration of the Earth; the Voyager missions to Jupiter and Saturn; the possibility of time travel; Einstein's theories; the life cycle of stars; determining the origin of the Universe; the brain and the evolution of intelligence; how we might communicate with alien civilizations; the continued survival of the human race versus the threat of nuclear destruction.

When Cosmos was first broadcast in 1980, our world--and the context of Carl Sagan's eloquent "personal journey"--was a different place. The late Dr. Sagan would be pleased to witness the cooling of the Cold War, the continued exploration of space, and ongoing efforts to curb our destructive dependence on fossil fuels. For Sagan's series is far more than a guided tour through "billions and billions" of stars and galaxies. It remains a profound plea for the unity of humankind, for the recognition that "we are a way for the universe to know itself," with an obligation to know our origin, our place in the universe, and our future potential.

In the course of 13 fascinating hours, Cosmos spans its own galaxy of topics to serve Sagan's theme, each segment deepening our understanding of how we got from there (simple microbes in the primordial mud) to here (space-faring civilization in the 21st century). In his "ship of the imagination," Sagan guides us to the farthest reaches of space and takes us back into the history of scientific inquiry, from the ancient library of Alexandria to the NASA probes of our neighboring planets. Upon this vast canvas Sagan presents the "cosmic calendar," placing the 15-billion-year history of the universe into an accessible one-year framework, then filling it with a stunning chronology of events, both interstellar and earthbound.

From the lives of the stars to creation theories, functions of the human brain, and the ongoing search for extraterrestrial intelligence, Cosmos asks big questions. When appropriate, Sagan offers big answers, or asks still bigger--and yes, even spiritual--questions at the boundaries of science and religion. What's most remarkable about Cosmos is that it remains almost entirely fresh, with few updates needed to the science that Sagan so passionately celebrates. It is no exaggeration to say that Cosmos--for all the debate it may continue to provoke--is a vital document for humanity at a pivotal crossroads of our history. --Jeff Shannon
