Book Description
The captivating possibilities of extraterrestrial life on exoplanets, based on current scientific knowledge of existing worlds and forms of life It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring readers on a marvelous experimental voyage through the possibilities of life--unlike anything we have experienced so far--that could exist on planets outside our own solar system. Life could be out there in many forms: on frozen worlds, living in liquid oceans beneath ice and communicating (and even battling) with bubbles; on super-dense planets, where they would have evolved body types capable of dealing with extreme gravity; on tidally locked planets with one side turned eternally toward a star; and even on "rogue worlds," which have no star at all. Yet this is no fictional flight of fancy: the authors take what we know about exoplanets and life on our own world and use that data to hypothesize about how, where, and which sorts of life might develop. Imagined Life is a must-have for anyone wanting to learn how the realities of our universe may turn out to be far stranger than fiction.

Book Description
Discover the real science behind 2001, ET, Signs, and all your favorite fictional alien civilizations. As space telescopes continue to search for life in this unearthly Universe, the crucial questions remain unanswered. Are we awake to the revolutionary effects on human society and science that alien contact will bring? And how is it possible to imagine the unknown? The Science of Aliens tells the compelling story of how the portrayal of alien life has evolved over time. Taking examples from science, film, and fiction, this book showcases how scholars, filmmakers, and authors have devoted their energies to imagining life beyond this Earth. From Copernicus to Kubrick, The Science of Aliens is a fascinating account for anyone interested in extraterrestrials. Otherworldly topics include: What Xenomorphs from Alien and Na’vi from Avatar have in common Darwin among aliens Extraterrestrials in Einstein’s sky Aliens in our space age And so much more Visualize the unknown and redefine your place in a changing cosmos with The Science of Aliens.

Book Description
"A fascinating and useful handbook to both the science and science fiction of extraterrestrial life. Cohen and Stewart are amusing, opinionated, and expert guides. I found it a terrific and informative piece of work-nothing else like it!" -Greg Bear "I loved it." -Larry Niven "Ever wonder about what aliens could be like? The world authority is Jack Cohen, a professional biologist who has thought long and hard about the vast realm of possibilities. This is an engaging, swiftly moving study of alien biology, a subject with bounds and constraints these authors plumb with verve and intelligence." -Gregory Benford "A celebration of life off Earth. A hearteningly optimistic book, giving a much-needed antidote to the pessimism of astrobiologists who maintain that we are alone in the universe-a stance based on a very narrow view of what could constitute life. A triumph of speculative nonfiction." -Dougal Dixon, author of After Man: A Zoology of the Future

Book Description
What would life on other planets look like? Forget the little green men, alien life is likely to be completely unrecognisable -we haven't even discovered all the life on our own planet. This visionary book offers some of the most radical but scientifically accurate thinking on the possibility of life on other planets ever conceived. Using broad principles of Earthly biology and expanding on them laterally, Cohen and Stewart examine what could be out there. Redefining our whole concept of what 'life' is, they ask whether aliens could live on the surface of a star, in the vacuum of space or beneath the ice of a frozen moon. And whether life could exist without carbon or DNA -or even without matter at all. They also look at 'celebrity aliens' from books and films -most of which are biologically impossible. Jack Cohen is an 'alien consultant' to many writers, advising what an alien could and couldn't look like. (E. T. go home -you do not pass the test). But this book is as much about the latest discoveries in Earthly biology as well as life on other planets. It's a serious yet entertaining science book, as you'd expect from the bestselling authors of THE SCIENCE OF DISCWORLD.

DISCOVER HOW LIFE REALLY WORKS - ON EARTH AND IN SPACE 'A wonderfully insightful sidelong look at Earthly biology' Richard Dawkins 'Crawls with curious facts' Sunday Times _________________________ We are unprepared for the greatest discovery of modern science. Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing. Using his own expert understanding of life on Earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like. This is the story of how life really works, on Earth and in space. _________________________ 'An entertaining, eye-opening and, above all, a hopeful view of what - or who - might be out there in the cosmos' Philip Ball, author of Nature's Patterns 'A fascinating insight into the deepest of questions: what might an alien actually look like' Lewis Dartnell, author of Origins 'If you don't want to be surprised by extraterrestrial life, look no further than this lively overview of the laws of evolution that have produced life on earth' Frans de Waal, author of Mama's Last Hug

Book Description
The quest for extraterrestrial life doesn't happen only in science fiction. This book describes the startling discoveries being made in the very real science of astrobiology, an intriguing new field that blends astronomy, biology, and geology to explore the possibility of life on other planets. Jeffrey Bennett takes readers beyond UFOs to discuss some of the tantalizing questions astrobiologists grapple with every day: What is life and how does it begin? What makes a planet or moon habitable? Is there life on Mars or elsewhere in the solar system? How can life be recognized on distant worlds? Is it likely to be microbial, more biologically complex--or even intelligent? What would such a discovery mean for life here on Earth? Come along on this scientific adventure and learn the astonishing implications of discoveries made in this field for the future of the human race. Bennett, who believes that "science is a way of helping people come to agreement," explains how the search for extraterrestrial life can help bridge the divide that sometimes exists between science and religion, defuse public rancor over the teaching of evolution, and quiet the debate over global warming. He likens humanity today to a troubled adolescent teetering on the edge between self-destruction and a future of virtually limitless possibilities. Beyond UFOs shows why the very quest to find alien life can help us to grow up as a species and chart a course for the stars. In a new afterword, Bennett shares the most recent developments in extrasolar research, and discusses how they might further our quest to find alien life.
