"Lisa's breezy narrative style invites you to experience with her the challenges and joys of being a scientist on the frontier of discovery." —Neil deGrasse Tyson, Astrophysicist, American Museum of Natural History "Horizon-expanding... [Kaltenegger] has something of Sagan’s knack for eliciting wonder." —The Times "A superb testament to the scientific virtue of curious wonder." —Wall Street Journal For thousands of years, humans have wondered whether we're alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life? As founding director of Cornell University's Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview - planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality. With the James Webb Space Telescope and Dr. Kaltenegger’s pioneering work, she shows that we live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide, Dr. Kaltenegger shows how we discover not merely new continents, like the explorers of old, but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we're not alone?

Winner of the 2019 Phi Beta Kappa Award for Science "A valuable perspective on the most important problem of our time." —Adam Becker, NPR Light of the Stars tells the story of humanity’s coming of age as we realize we might not be alone in this universe. Astrophysicist Adam Frank traces the question of alien life from the ancient Greeks to modern thinkers, and he demonstrates that recognizing the possibility of its existence might be the key to save us from climate change. With clarity and conviction, Light of the Stars asks the consequential question: What can the likely presence of life on other planets tell us about our own fate?

Master how the Bible and your Christian faith play into this Christopher Columbus of events. WALL STREET JOURNAL, CNN, FOX NEWS, NPR, NATIONAL GEOGRAPHIC and countless others have featured cover stories on NASA's KEPLER SPACECRAFT and its epic mission to discover other Earths. Kepler's science team has now identified over three thousand five hundred alien planets, but their mission is much more ambitious. Of these new found worlds, five have been confirmed as orbiting within their star's habitable zone. NASA is on the brink of their holy grail: an Earth-size world basking in the warm tropical glow of a Sun-like star capable of water oceans and breathable air. This book empowers Christians with not only an exciting understanding of the mission, but how to counteract the god-less interpretations heard on media-outlets around the world when NASA announces the discovery of other Earths. Prepare yourself with a Christian Spaceview.

A fun-filled, highly illustrated, science-based exploration into one of the universe’s greatest mysteries—does life exist beyond Earth?—from bestselling and award-winning author Stacy McAnulty. Spoiler: Scientists haven’t discovered life beyond Earth, not even a single teeny-tiny organism. But there’s a whole lot of outer space, and humans have searched only a fraction of a fraction of it. So do you believe in the possibility of life out there? Or do you think Earth is perfectly unique in its ability to grow organisms? Where Are the Aliens? takes readers on a journey of theories and discoveries, from the big bang and primordial soup, to how the ancient Greeks considered the cosmos, to the technology used today to listen and (possibly!) communicate with far-off exoplanets. Packed with playful illustrations and fascinating factoids, this is the perfect book for anyone who has ever looked up and asked, "What's out there?"

Considers the plausibility of alien life and what creatures living on extrasolar planets might be like, drawing on scientific sources to depict alien creatures who have adapted to the unique characteristics of their respective environments.

Are we alone in the universe? Probably not, say most scientists.

A journey of stunning discovery by the author of Cloven Hooves. Humanity has been "rescued" from a toxic and dangerous Earth by the enigmatic Arthropalan and inserted into the fragile ecologies of twin alien worlds--where they must make no environmental impact.
