This is an intriguing overview of the ways in which science could find evidence for extraterrestrial life. Are we alone in the universe, or is life a universal phenomenon? For fifty years, astronomers in SETI (Search for Extraterrestrial Intelligence) have scanned the universe for intelligent signals, but with no success. This intriguing book examines the inherent problems of scanning the universe for radio or optical signals form an alien intelligence - including the difficulties of attempting communication with a species possessing completely unknown forms of technology and the vast distances that communications would have to travel to reach us. It then goes on to discuss other ways of finding evidence of extraterrestrial life and the possibility of alien space technology already existing within our own solar system. The final chapter looks at the use of the scientific method to test various hypotheses and weed out the fantasy factor, which so often interferes with serious attempts to find hard evidence of extraterrestrial life.
