The big questions of astrophysicist Mario Livio's new book Is Earth Exceptional? The Quest for Cosmic Life are as close as we get to an ultimate curiosity -- questions about the origin of life, the universe, and where and how those two intersect. Dr. Livio worked with the Hubble Space Telescope and is a bestselling author of seven books. Together with Jack Szostak, a biochemist and Nobel laureate, he's written a kind of cosmic “what-dunnit” that shifts between the many and various disciplines that may someday provide the answers they seek about life's origins.
