The American astronomer Carl Sagan (1934-1996) was one of the best-known scientists of his time. A prolific writer and television personality, he was creator and host of Cosmos, an enormously popular television series that explained the wonders and intricacies of astronomy to millions of television viewers. Gifted with the ability to communicate difficult scientific concepts to the average person, Sagan opened up the wonders of science to hundreds of thousands more through his many books and magazine articles. But in addition to his talents as a science popularizer, Sagan was a first-rate scientist. Ever persistent in exploring the possibility of life on other planets in the Universe, he was a pioneer in the field now known as astrobiology, a major thrust of NASA's current planetary explorationsThis book takes a fascinating look at all aspects of the life of Carl Sagan: Sagan the working scientist, who was an inspired and creative participant in the forefront of the new and exciting era of astronomy opened up by the technological breakthroughs of the space age; Sagan the advocate for science, who could expound on the beauties and joys of science as well as point out the follies and foibles of pseudoscience; and Sagan the activist, who helped raise our awareness to the perils of the Nuclear Age that threatened all of us. Following the arc of Sagan's personal and professional life, this book examines both the man and the provocative ideas he brought to this new era, always seeking to capture the infectious enthusiasm and love of communication that infused Carl Sagan's life and work.

Astronomer, planetary scientist, astrophysicist, exobiologist, educator, public figure, skeptic—all these hats represent important parts of Carl Sagan's complex, multifaceted career. Perhaps best known as the host of the popular television series Cosmos, Sagan offered to the world his extraordinary gift for cross-disciplinary research, his deep well of integrated visions and fruitful ideas, his vivid imagination, and his wealth of nonstop enthusiasm. This concise, lively biography examines Carl Sagan's steady growth as a man, as a scientist, and as a communicator—a man who had both odd quirks and great charisma, who had an immensely eclectic knowledge base and a unique understanding of the central place of science in the human experience, all of which dovetailed smoothly with his phenomenal ability to communicate. Separate chapters are devoted to Sagan's interest in the origin of life, the search for extraterrestrial intelligence (SETI), and his work on Cosmos, where he collaborated with Ann Druyan, whom he eventually married and who remained his wife to the end of his life. There are also sections on Sagan's public advocacy for science and critical stance toward pseudoscience and his role as an activist for the environment and the safe use of atomic power.This updated, paperback edition of Carl Sagan: A Biography contains many new photos as well as textual additions by Ann Druyan. Veteran science writers Spangenburg and Moser have captured much of the enthusiasm, gift for effective communication, and unflinching honesty that characterized Carl Sagan's life and career.
