The search for extraterrestrial intelligence

In nontechnical language, the author describes the projects and future possibilities in the search for extraterrestrial intelligence. Within the infinite universe there exists the infinite possibility that we are not alone. Since 1959, scientists engaged in the SETI effort (Search for Extraterrestrial Intelligence) have been quietly searching the cosmos for evidence of intelligent life--a discovery, that, if made, will be the most dramatic event in human history. And it's getting harder to detect signals from space--the very technology that makes it possible to detect other civilizations is now clogging the skies with radio pollution from ground-based radio transmitters, spy satellites, and communications satellites. In this intriguing behind-the-scenes view of the search for ET, McDonough reveals recent scientific advances and controversies, battles with the government to get various projects funded, and international projects--particularly those of the Soviets. He also provides an entertaining look at Alien in literature and popular culture, as well some exciting speculation for the future.
