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?

"In this EK title Roush investigates a topic that has fascinated him since college -- the possibility and probability of life, intelligent or otherwise, in the universe. The book covers the history and science of our search for extraterrestrial life, and investigates what that search means for us as a species, as well as what the implications of finding life on other planets might mean for life on Earth. The book covers various iterations of SETI, or the search for extraterrestrial intelligence, both in listening for messages from space as well as sending them. Roush also covers more recent efforts to find exoplanets, worlds similar enough to our own to possibly harbor life in even very basic forms. Some of this research is driven by discoveries of 'extremophile' life here on Earth in places and conditions previously considered to be unconducive to life forms. Roush co-taught a course on this topic last year at MIT"--

In December 2018, a bright blue light appeared over New York City. In thousands of Instagram posts and tweets, New Yorkers wondered: Could the light be signs of aliens? Although the lights turned out to be connected to a Queens powerplant, the curiosity they sparked speaks to the fascination we have for signs of life outside of Earth. The articles in this collection relate to the search for extraterrestrial life, detailing both the science that guides us toward it as well as the communities who believe it is already among us. In book reviews, op-eds, and feature reporting, scientists and journalists attempt to make sense of the question: Are we alone? Features such as a glossary and media literacy questions and terms engage readers beyond the text.

Space is again in the headlines. E-billionaires Jeff Bezos and Elon Musk are planning to colonize Mars. President Trump wants a "Space Force" to achieve "space dominance" with expensive high-tech weapons. The space and nuclear arms control regimes are threadbare and disintegrating. Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastrophes (from extreme climate change to runaway artificial superintelligence), looking beyond the earth for solutions might seem like a sound strategy for humanity. And indeed, bolstered by a global network of fervent space advocates-and seemingly rendered plausible, even inevitable, by oceans of science fiction and the wizardly of modern cinema-space beckons as a fully hopeful path for human survival and flourishing, a positive future in increasingly dark times. But despite even basic questions of feasibility, will these many space ventures really have desirable effects, as their advocates insist? In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons. The most important practical finding of Space Age science, also rarely emphasized, is the discovery that we live on Oasis Earth, tiny and fragile, and teeming with astounding life, but surrounded by an utterly desolate and inhospitable wilderness stretching at least many trillions of miles in all directions. As he stresses, our focus must be on Earth and nowhere else. Looking to the future, Deudney provides compelling reasons why space colonization will produce new threats to human survival and not alleviate the existing ones. That is why, he argues, we should fully relinquish the quest. Mind-bending and profound, Dark Skies challenges virtually all received wisdom about the final frontier.

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 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

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.

This book is a collection of essays written by the very scientists and engineers who have led, and continue to lead, the scientific quest known as SETI, the search for extraterrestrial intelligence. Divided into three parts, the first section, ‘The Spirit of SETI Past’, written by the surviving pioneers of this then emerging discipline, reviews the major projects undertaken during the first 50 years of SETI science and the results of that research. In the second section, ‘The Spirit of SETI Present’, the present-day science and technology is discussed in detail, providing the technical background to contemporary SETI instruments, experiments, and analytical techniques, including the processing of the received signals to extract potential alien communications. In the third and final section, ‘The Spirit of SETI Future’, the book looks ahead to the possible directions that SETI will take in the next 50 years, addressing such important topics as interstellar message construction, the risks and assumptions of interstellar communications, when we might make contact, what aliens might look like and what is likely to happen in the aftermath of such a contact.

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.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

An astronomer explores the science of astrobiology in this “serious but accessible examination of the prospects for finding life elsewhere in the universe” (Sean Carroll, author of The Big Picture). Describing the most recent discoveries made with space exploration technology, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, astronomer Jon Willis asks readers to consider five possible scenarios for finding extraterrestrial life. He reviews what we know and don’t know about the life-sustaining potential of Mars’s subsoil ice and the water-ice moons Europa and Enceladus. He also looks at Saturn’s moon Titan through the lens of our own planet’s ancient past. In this concise yet far-reaching volume, Willis even looks beyond our solar system, investigating the top candidates for a “second Earth” in a myriad of exoplanets. “Through humorous, concise, accessible writing, Willis eloquently presents the growing—though still circumstantial—evidence that we are not alone."—Publishers Weekly (starred review)

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.
