The possibility that alien life exists in the universe is among the most profound of human conjectures, which today is being investigated not just by science-fiction writers but by scientists.
Astrobiology presents an expert guide to this compelling field of science. It shows how the tell- tale signatures of life on Earth might hold the key to detecting life beyond our planet; explores the many planets beyond our Solar System discovered by NASA's Kepler and TESS missions; and explains alien- hunting touchstones such as Fermi's Paradox, the Drake Equation, and the 'Wow' signal.
