How likely is it that somewhere 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 Orson Welles's 1938 radio broadcast, The War of the Worlds, leading to significant anxiety among some listeners. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of the book 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? 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.

PEN Literary Award Winner: “The best, most entertaining examination of the possibility of other life in the universe since [Carl] Sagan’s best work.” —Boulder Daily Camera It’s been decades since Carl Sagan first addressed the general public about the possibility of extraterrestrial life from a scientist’s perspective. We’ve learned a lot in those years, and now planetary scientist David Grinspoon investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident, or in some sense the “purpose” of this universe? And how can we, working from the Earth-centric definition of “life,” even begin to think about the varieties of life-forms on other planets? In accessible, lively prose, and using the topic of extraterrestrial life as a mirror with which to view human beliefs, evolution, history, and aspirations, Grinspoon takes us on a three-part journey—the history of our expanding awareness of other planets and our ideas on alien life dating back to the earliest days of astronomy; the science of cosmic evolution and the evolution of life on Earth, including a critique of the “Rare Earth hypothesis”; and the beliefs that humans hold, addressing the limits of our ability to conceptualize or communicate with intelligent aliens and the scientific and philosophical implications of far-future evolutionary possibilities. Rich in personal and often amusing anecdotes, Lonely Planets explores the shifting boundary between planetary science and natural philosophy, and reveals how the search for extraterrestrial life unites our spiritual and scientific quests for connection with the cosmos. Includes a new foreword about recent Mars discoveries “An outstanding introduction to cosmic evolution.” —San Jose Mercury News “[A] terrific book.” —San Diego Union-Tribune “A personable chat on life, the universe and everything.” —Publishers Weekly
