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.

In the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in the universe will trigger one of the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world’s most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

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?

This groundbreaking book demonstrates that between the results of the 1976 Viking I lander and the latest scientific discoveries – from fertile Martian soil to microbe-ridden meteorites – there is a powerful case for life on the Red Planet and beyond. Exploring what forms extraterrestrial life might take and where it may reside, We Are Not Alone provides a captivating tour of the Solar System and shows that it’s much more crowded than we previously realised. Dirk Schulze-Makuch is Associate Professor in Astrobiology at Washington State University. David Darling is an acclaimed popular science writer and bestselling author.

Fermi S Paradox Cosmology And Life

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.

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.

Life In Space

A truly interdisciplinary endeavor, astrobiology looks at the evidence of astronomy, biology, physics, chemistry, and a host of other fields. A grand narrative emerges, beginning from the smallest, most common particles yet producing amazing complexity and order. Lucas Mix is a congenial guide through the depths of astrobiology, exploring how the presence of planets around other stars affects our knowledge of our own planet; how water, carbon, and electrons interact to form life as we know it; and how the processes of evolution and entropy act upon every living thing.

“A definitive guide to astronomy’s hottest field.” —The Economist Since its formation nearly five billion years ago, our planet has been the sole living world in a vast and silent universe. But over the past two decades, astronomers have discovered thousands of “exoplanets,” including some that could be similar to our own world, and the pace of discovery is accelerating. In a fascinating account of this unfolding revolution, Lee Billings draws on interviews with the world’s top experts in the search for life beyond earth. He reveals how the search for exoplanets is not only a scientific challenge, but also a reflection of our culture’s timeless hopes, dreams, and fears.
