Is Anyone Out There?

In 1960, an intrepid astrophysicist at the National Radio Astronomy Observatory in Green Bank, West Virginia, set out to tune an ear to the noise from the deepest points in the universe. Armed with a landmark paper in the scientific journal Nature and his own startling observations from his graduate school days at Harvard, Frank Drake wrangled many precious hours of the radio telescope's time to begin his search for extraterrestrial intelligence. Drake's labor (which he named Project Ozma after the princess in L. Frank Baum's story Ozma of Oz) not only proved that we already possess the means to detect other intelligent beings in the cosmos, but yielded a suspected signal from a distant star. Although the signal turned out to be from our world, Drake parlayed the excitement generated by Project Ozma into a lifelong mission, setting a goal that could change the course of history - the scientific confirmation that we are not alone. In a captivating and accessible narrative, Drake and writer Dava Sobel take the reader to remote observatories around the world and behind the closed doors of international conferences dedicated to detect extraterrestrial intelligence. Some of the greatest names in science - Carl Sagan, Otto Struve, Philip Morrison, Melvin Calvin, Edward Purcell, Francis Crick, Bernard Oliver - have worked with Drake to untangle both the practical elements of detecting alien radio signals and the philosophical questions raised by the existence of other sentient beings in the universe. What do we stand to gain from interstellar contact? Which facts about ourselves do we want to communicate to extraterrestrials? How should we respond to a signal from another civilization? While maintaining an absorbing anecdotal charm, Is Anyone Out There? grapples with these questions and thoughtfully provides a clear explanation of the scientific ideas and technology that define the search.
