One of the world’s leading scientists explains why—and how—the search for intelligent life beyond Earth should be expanded. Fifty years ago, a young astronomer named Frank Drake first pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). After a half-century of scanning the skies, however, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. Physicist and astrobiologist Paul Davies has been closely involved with SETI for three decades and chairs the SETI Post-Detection Taskgroup, charged with deciding what to do if we’re suddenly confronted with evidence of alien intelligence. He believes the search so far has fallen into an anthropocentric trap—assuming that an alien species will look, think, and behave much like us. In this provocative book Davies refocuses the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us, and how we should respond if it does.

If the discovery of life elsewhere in the universe is just around the corner, what would be the consequences for religion? Would it represent another major conflict between science and religion, even leading to the death of faith? Some would suggest that the discovery of any suggestion of extraterrestrial life would have a greater impact than even the Copernican and Darwinian revolutions. It is now over 50 years since the first modern scientific papers were published on the search for extraterrestrial intelligence (SETI). Yet the religious implications of this search and possible discovery have never been systematically addressed in the scientific or theological arena. SETI is now entering its most important era of scientific development. New observation techniques are leading to the discovery of extra-solar planets daily, and the Kepler mission has already collected over 1000 planetary candidates. This deluge of data is transforming the scientific and popular view of the existence of extraterrestrial intelligence. Earth-like planets outside of our solar system can now be identified and searched for signs of life. Now is a crucial time to assess the scientific and theological questions behind this search. This book sets out the scientific arguments undergirding SETI, with particular attention to the uncertainties in arguments and the strength of the data already assembled. It assesses not only the discovery of planets but other areas such as the Fermi paradox, the origin and evolution of intelligent life, and current SETI strategies. In all of this it reflects on how these questions are shaped by history and pop culture and their relationship with religion, especially Christian theology. It is argued that theologians need to take seriously SETI and to examine some central doctrines such as creation, incarnation, revelation, and salvation in the light of the possibility of extraterrestrial life.

Aliens are big in America. Whether they’ve arrived via rocket, flying saucer, or plain old teleportation, they’ve been invading, infiltrating, or inspiring us for decades, and they’ve fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they’ve visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program’s senior astronomer, Seth Shostak explains in this engrossing book, it’s entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider’s view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.

In a universe as large as this, it would be surprising if earth was the only inhabited planet. Everything we know about cosmology today, suggested that life should be common. Almost certainly some of that would be similar to ourselves, and would also probably be using radio technology in much the way that we do. We should be able to pick up these signals, with the powerful radio telescopes we have today, and the surprising thing is that after 50 years of continuous listening, we have not yet detected a single one. Fermis paradox relates to this finding, but in its original form, was posed as a question, as to why, in a universe such as this, we have no knowledge of the extraterrestrial life which should be common. Many answers have been proposed, none of them satisfactory, and this book looks at the changes which have taken place since Fermis day, both with respect to the origin and evolution of life, and the advancing trends in modern cosmology, to provide current information from which readers can form their own opinion. The author presents a personal view, which is hypothetical and speculative, but consistent with facts nonetheless.

It's been nearly four decades since Carl Sagan first addressed the general public from a scientist's perspective, confronting the possibility of extraterrestrial life. We've learned a lot in those years, and planetary scientist David Grinspoon is well prepared to explore this field with a new generation of readers. In Lonely Planets, Grinspoon investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident or in some sense the "purpose" of this universe? And how can we, working from the Earth-centric definition of "life," even begin to think about the varieties of life-forms on other planets? In accessible, lively prose, and using the topic of extraterrestrial life as a mirror with which to view human beliefs, evolution, history, and aspirations, Grinspoon takes readers on a three-part journey. History is an overview of our expanding awareness of other planets, from the observations of seventeenth-century natural philosophers to modern-day space exploration. It traces the history of our ideas on alien life to the earliest days of astronomy, and shows how these beliefs have changed with humanity's evolving self-image. Science tells the story of cosmic evolution and the evolution of life on Earth. Here, Grinspoon disputes the recent "Rare Earth hypothesis," which argues that Earth is unique for sprouting advanced life-forms, maintaining instead that life is likely to be well adapted to a wide variety of planets. He questions conventional assumptions of what is required for a planet to come to life, scrutinizing current ideas and evidence for life on Mars, Venus, and the moons of Jupiter, and challenging readers to think about other life-forms that may exist on other worlds. Belief discusses the limits of our abilities to conceptualize or communicate with intelligent aliens living on planets circling distant stars. Grinspoon speculates on what intelligent life might become, eventually, on Earth and elsewhere, and the implications, both scientific and philosophical, of these far-future evolutionary possibilities. Written with authority and edge, and rich in personal,often amusing anecdotes, Lonely Planets explores the shifting boundary between planetary science and naturalphilosophy and reveals how the search for extraterrestrial life unites our spiritual and scientific quests for connection with the cosmos.

The search for extra-terrestrial intelligence (SETI) raises a number of scientific/philosophical questions. If we are the only conscious, intelligent species in the galaxy, why? If we are not, given that other cultures must be more technically advanced than us, why haven't we met them yet?

If you are interested in how researchers plan to search the heavens for signs of intelligent life, you should have this book. SETI 2020 is a new, and remarkably comprehensive study of how scientists busy with the Search for Extraterrestrial Intelligence (SETI) should direct their efforts between now and the year 2020. Distilling the work of dozens of top SETI experts, astronomers, and technology mavens, this book gives an overview of the problem of finding evidence for extraterrestrial technologies, and how to best address it. New radio telescopes consisting of large arrays of relatively small antennas are proposed and detailed. So are new types of antennas that can survey the entire sky at once. Of particular interest is the extensive treatment of optical SETI -- the search for signals beamed our way using high-powered, pulsed lasers or their equivalent. A book that's interesting for both the layman and the technically sophisticated, SETI 2020 is the definitive publication in this fascinating field.
