The father-son team of David E. Fisher and Marshall Jon Fisher brings the study of extraterrestrial life down to earth in this informative and entertaining book. In the anecdotal style that is their hallmark, the Fishers trace humankind's attempts to discover life on other worlds -- a discipline known in scientific circles as exobiology.The book begins in the seventeenth century with the story of Giordano Bruno, whose interest in the mysteries of the universe caused him to be burned at the stake. It continues through the present day, highlighting recent scientific breakthroughs: evidence of fossilized organisms in a meteorite from Mars; planets orbiting a variety of different stars; and a possible ocean on one of Jupiter's moons. Underscoring the significance of these controversial discoveries are vast improvements in computer technology and radio astronomy that are making it possible for the first time to search realistically for signals from civilizations beyond our solar system.Guidedby history and by science, this book separates fantasies about aliens from the search for documented evidence of extraterrestrial life. Strangers in the Night will be of great interest to anyone who has looked into the night sky and wondered if anyone was looking back.
