Life on Other Worlds: The 20th-Century Extraterrestrial Life Debate
Steven J. Dick

Dick, an astronomer and historian of science at the US Naval Observatory, offers an antidote to the sensationalism surrounding the search for extraterrestrial life in this overview of the history of theories of life on other planets, recent advances in planetary science, and the latest thinking on the likelihood of life in outer space. He also demystifies the agenda of sensationalists who seek to impose their own radical cosmology based on conjecture rather than scientific fact.
