“Remarkably upbeat, and imbued with wit, wisdom and a palpable sense of awe over our universe.”—Tucson Weekly Most of us are aware of our own mortality, but few among us know what science, with insights yielded from groundbreaking new research, has to say about endings on a larger scale. Enter astronomer Chris Impey, who chronicles the death of the whole shebang: individual, species, bio- sphere, Earth, Sun, Milky Way, and, finally, the entire universe. With a healthy dose of humor, How It Ends illuminates everything from the technologies of human life extension and the evolutionary arms race between microbes and men to the inescapable dimming of the Sun and the ultimate “big rip,” giving us a rare glimpse into a universe without us.

“Impey combines the vision of a practicing scientist with the voice of a gifted storyteller.”—Dava Sobel In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past. Impey uses this concept—"look-back time"—to take us on an intergalactic tour that is simultaneously out in space and back in time. Performing a type of cosmic archaeology, Impey brilliantly describes the astronomical clues that scientists have used to solve fascinating mysteries about the origins and development of our universe. The milestones on this journey range from the nearby to the remote: we travel from the Moon, Jupiter, and the black hole at the heart of our galaxy all the way to the first star, the first ray of light, and even the strange, roiling conditions of the infant universe, an intense and volatile environment in which matter was created from pure energy. Impey gives us breathtaking visual descriptions and also explains what each landmark can reveal about the universe and its history. His lucid, wonderfully engaging scientific discussions bring us to the brink of modern cosmology and physics, illuminating such mind-bending concepts as invisible dimensions, timelessness, and multiple universes. A dynamic and unforgettable portrait of the cosmos, How It Began will reward its readers with a deeper understanding of the universe we inhabit as well as a renewed sense of wonder at its beauty and mystery.

Astrobiology–the study of life in space–is one of today’s fastest growing and most popular fields of science. In this compelling, accessible, and elegantly reasoned new book, award-winning scholar and researcher Chris Impey explores the foundations of this rapidly developing discipline, where it’s going, and what it’s likely to find. The journey begins with the earliest steps of science, gaining traction through the revelations of the Renaissance, including Copernicus’s revolutionary declaration that the Earth was not the center of the universe but simply a planet circling the sun. But if Earth is not the only planet, it is so far the only living one that we know of. In fascinating detail, The Living Cosmos reveals the incredible proliferation and variety of life on Earth, paying special tribute to some of its hardiest life forms, extremophiles, a dizzying array of microscopic organisms compared, in Impey’s wise and humorous prose, to superheroes that can survive extreme heat and cold, live deep within rocks, or thrive in pure acid. From there, Impey launches into space, where astrobiologists investigate the potential for life beyond our own world. Is it to be found on Mars, the “death planet” that has foiled most planetary missions, and which was wet and temperate billions of years ago? Or on Venus, Earth’s “evil twin,” where it rains sulfuric acid and whose heat could melt lead? (“Whoever named it after the goddess of love had a sorry history of relationships.”) The answer may lie in a moon within our Solar System, or it may be found in one of the hundreds of extra-solar planets that have already been located. The Living Cosmos sees beyond these explorations, and imagines space vehicles that eschew fuel for solar- or even nuclear-powered rockets, all sent by countries motivated by the millions to be made in space tourism. But The Living Cosmos is more than just a riveting work about experiment and discovery. It is also an affecting portrait of the individuals who have devoted their lives to astrobiology. Illustrated throughout, The Living Cosmos is a revelatory book about a science that is changing our view of the universe, a mesmerizing guide to what life actually means and where it may–or may not–exist, and a stunning work that explains our past as it predicts our future. From the Hardcover edition.

Ever since Carl Sagan first predicted that extraterrestrial civilizations must number in the millions, the search for life on other planets has gripped our imagination. Is Earth so rare that advanced life forms like us--or even the simplest biological organisms--are unique to the universe? How to Find a Habitable Planet describes how scientists are testing Sagan's prediction, and demonstrates why Earth may not be so rare after all. James Kasting has worked closely with NASA in its mission to detect habitable worlds outside our solar system, and in this book he introduces readers to the advanced methodologies being used in this extraordinary quest. He addresses the compelling questions that planetary scientists grapple with today: What exactly makes a planet habitable? What are the signatures of life astronomers should look for when they scan the heavens for habitable worlds? In providing answers, Kasting explains why Earth has remained habitable despite a substantial rise in solar luminosity over time, and why our neighbors, Venus and Mars, haven't. If other Earth-sized planets endowed with enough water and carbon are out there, he argues, chances are good that some of those planets sustain life. Kasting describes the efforts under way to find them, and predicts that future discoveries will profoundly alter our view of the universe and our place in it. This book is a must-read for anyone who has ever dreamed of finding other planets like ours--and perhaps even life like ours--in the cosmos.

Book 1 in the New York Times bestselling trilogy, perfect for fans of Battlestar Gallactica and Passengers! WHAT DOES IT TAKE TO SURVIVE ABOARD A SPACESHIP FUELED BY LIES? Amy is a cryogenically frozen passenger aboard the spaceship Godspeed. She has left her boyfriend, friends--and planet--behind to join her parents as a member of Project Ark Ship. Amy and her parents believe they will wake on a new planet, Centauri-Earth, three hundred years in the future. But fifty years before Godspeed's scheduled landing, cryo chamber 42 is mysteriously unplugged, and Amy is violently woken from her frozen slumber. Someone tried to murder her. Now, Amy is caught inside an enclosed world where nothing makes sense. Godspeed's 2,312 passengers have forfeited all control to Eldest, a tyrannical and frightening leader. And Elder, Eldest's rebellious teenage heir, is both fascinated with Amy and eager to discover whether he has what it takes to lead. Amy desperately wants to trust Elder. But should she put her faith in a boy who has never seen life outside the ship's cold metal walls? All Amy knows is that she and Elder must race to unlock Godspeed's hidden secrets before whoever woke her tries to kill again.
