Directed toward both believers and skeptics, this exploration of the possibilities of life elsewhere in the universe lays out scientific theories and investigations using the fundamentals of astrobiology, a growing branch of science dedicated to searching both for life on planets in our solar system and possible habitable planets outside of the Milky Way. This analysis recounts the history of the universe in order to determine the likelihood of other life and examines the conditions necessary to support its existence. More than 70 percent of the universe remains unexplored, and this speculative book questions what there is to find.
