In these lively and fascinating essays, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we’ll ever make contact. Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game? For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

Do Aliens Exist? And if they do - what would they look like? Where would they live? Would they be conscious beings? And what would happen if they found us? These are the biggest questions we've ever asked - and here, Professor Jim Al-Khalili, theoretical physicist and host of BBC Radio Four's The Life Scientific, blasts off in search of answers. Coming with him are Martin Rees, Ian Stewart, Louisa Preston, Monica Grady, Sara Seager, Paul Davies and a crack team of scientists and experts who've made it their life's work to discover the truth. So get ready to visit the ice boulders and hydrocarbon lakes of Saturn's moon Titan, meet the tiny eight-legged critters that could survive in space, and learn about the neuroscience behind belief in alien abductions. Along the way, you'll enter the mind of an octopus, work out the probability of us finding an alien civilisation and discover whether quantum computing might hold the secret to life itself. Lively, curious and filled with scientific insights fresh from the cutting edge of the Galaxy, Aliens is the perfect book for anyone who has ever looked up into the starry sky and wondered: are we alone?

Where would you look for alien life? An astronomer and science popularizer explains the basics of astrobiology to outline five plausible scenarios for finding extraterrestrials Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks readers to imagine--and choose among--five scenarios for finding life. He encourages us to wonder whether life might exist within Mars's subsoil ice. He reveals the vital possibilities on the water-ice moons Europa and Enceladus. He views Saturn's moon Titan through the lens of our own planet's ancient past. And, he even looks beyond our solar system, investigating the top candidates for a "second Earth" in a myriad of exoplanets and imagining the case of a radio signal arriving from deep space. Covering the most up-to-date research, this accessibly written book provides readers with the basic knowledge necessary to decide where they would look for alien life.

This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.

Discover the fascinating and cutting-edge science behind the greatest question of all: is there life beyond Earth? For millennia, we have looked up at the stars and wondered whether we are alone in the universe. In the last few years, scientists have made huge strides towards answering that question. In The Aliens are Coming!, comedian and bestselling science writer Ben Miller takes us on a fantastic voyage of discovery, from the beginnings of life on earth to the very latest search for alien intelligence. What soon becomes clear is that the hunt for extra-terrestrials is also an exploration of what we actually mean by life. What do you need to kickstart life? How did the teeming energy of the Big Bang end up as frogs, trees and quantity surveyors? How can evolution provide clues about alien life? What might it look like? (Probably not green and sexy, sadly.) As our probes and manned missions venture out into the solar system, and our telescopes image Earth-like planets with ever-increasing accuracy, our search for alien life has never been more exciting - or better funded. The Aliens are Coming! is a comprehensive, accessible and hugely entertaining guide to that search, and our quest to understand the very nature of life itself.

If extraterrestrials exist, where are they? What is the probability that somewhere out there in the universe an Earth-like planet supports an advanced culture? Why do so many people claim to have encountered Aliens? In this gripping exploration, scientist Don Lincoln exposes and explains the truths about the belief in and the search for life on other planets. In the first half of Alien Universe, Lincoln looks to Western civilization's collective image of Aliens, showing how our perceptions of extraterrestrials have evolved over time. The roots of this belief can be traced as far back as our earliest recognition of other planets in the universe—the idea of them supporting life was a natural progression of thinking that has fascinated us ever since. Our captivation with Aliens has, however, led to mixed results. The world was fooled in the nineteenth century during the Great Moon Hoax of 1835, and many people misunderstood, with calamitous results, Orson Welles's 1938 radio broadcast, The War of the Worlds. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of Alien Universe explores the scientific possibility of whether advanced Alien civilizations do exist. For many years, researchers have sought to answer Enrico Fermi’s great paradox—if there are so many planets in the universe and there is a high probability that many of those can support life, then why have we not actually encountered any Aliens? (Apologies to those who are sure we have.) Lincoln describes how modern science teaches us what is possible and what is not in our search for extraterrestrial civilizations. Whether you are drawn to the psychological belief in Aliens, the history of our interest in life on other planets, or the scientific possibility of Alien existence, Alien Universe is sure to hold you spellbound. -- Jocelyne DiRuggiero, Johns Hopkins University

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars--thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own--that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds. Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research. In a new afterword, Jayawardhana explains some of the most recent developments as we search for the first clues of life on other planets.
