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?"

Some of the greatest mysteries of the universe are questions that remain unanswered. Where did life on Earth come from? Since Earth exists in space, can life exist elsewhere in our galaxy? And if life does exist throughout the universe, where are all the aliens? Welcome to Fermi's paradox, defined as the clear lack of evidence for alien life in our universe despite the seemingly endless opportunities for it to emerge and flourish. It is a mystery that continues to spark the imaginations of people worldwide. Nowadays we are alone in the midst of the Great Silence that surrounds us. But what are the conditions for alien life forms to evolve on a planet and subsequently contact us? And how can we justify our loneliness, based on the idea that there are other living beings? This book discusses and examines the possible solutions to this paradox and also how they reflect on us, our past and our future.

EXO-TERRANS: WHERE ARE THE ALIENS?Suppose we woke up tomorrow to learn that extraterrestrial life had been discovered. What difference would that make? Set aside the extreme scenarios of popular fiction. The truth will probably be more mundane - not massive spaceships suddenly filling the sky but, instead, microorganisms found deep inside an ice-covered Moon, a non-random radio signal from a distant star system, or the ruins of a long-dead alien civilisation. What difference might those discoveries make?We know that life has emerged once. Why should it be so momentous to learn that it has emerged twice? The reason is that finding life elsewhere would radically change our picture of the Universe. At any point in time, humans will have explored only a tiny fraction of our galaxy, let alone the whole Universe. If life has emerged only once in that small sample, then it is possible that life on Earth is unique. (We might then use anthropic reasoning to explain why we inhabit the Universe's only inhabited planet: where else could observers find themselves?) But suppose we discover that life has emerged twice within our tiny sample - once on Earth, then again somewhere else. It would follow that life must have emerged a vast number of times across the galaxy. The discovery of independently emerging life would thus teach us that life is ubiquitous. And that discovery could have very significant implications. (The restriction to 'independently emerging' life is necessary because life found on meteors, asteroids, Mars or the Moon might have the same origin as life on Earth.)

In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million galaxies in the Universe, it stands to reason that somewhere out there, in the 14 billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.

We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies and television shows proliferate that attempt to answer this question and explore it. In OUT THERE Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer). What would the first aliens we meet look like? Would they be little green men or mere microbes? Would they be found on a planet in our own solar system or orbiting a star far, far away? Would they intend to harm us, and if so, how might they do it? And might they already have visited? OUT THERE is arranged in a simple question-and-answer format. The answers are delivered in Dr. Wall's informal but informative style, which mixes in a healthy dose of humor and pop culture to make big ideas easier to swallow. Dr. Wall covers questions far beyond alien life, venturing into astronomy, physics, and the practical realities of what long-term life might be like for we mere humans in outer space, such as the idea of lunar colonies, and even economic implications. Dr. Wall also shares the insights of some of the leading lights in space exploration today, and shows how the next space age might be brighter than ever.

'VISIONARY' Stephen Greenblatt 'So interesting... I recommend [Extraterrestrial] to people who have any interest in this extraordinary subject of life existing in other places than on Earth.' William Shatner (from Amazon.com) Harvard's top astronomer takes us inside the mind-blowing story of the first interstellar visitor to our solar system In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit, and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his theory and its profound implications: for science, for religion, and for the future of our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars-and to think critically about what's out there, no matter how strange it seems.

The great minds of the human race, employing ever more fabulous technology have peered into the depths of space and discovered that we exist on a tiny speck in a universe that is vast beyond comprehension. But there is one thing we have yet to discover: a single scrap of extraterrestrial life. We have heard no signals, found no alien picnic trash. The aliens who allegedly abduct people in the middle of the night have a strange way of evaporating in the harsh glare of scientific scrutiny. And so at the turn of the millennium we are in an intellectual fix: we know the universe only through its structure, its physical properties, its chemistry. Of its biology we can only guess. Are there creatures out there like us, with big brains and restless spirits? Or are we, for all intents and purposes, alone? If aliens exist -- if there really are intelligent creatures zooming around the galaxy -- then where in tar-nation are they? Washington Post reporter Joel Achenbach -- the author of Why Things Are and a commentator for National Public Radio -- puts the ET debate into the context of the space program, discoveries in astronomy, and the hunger for meaning and spiritual nourishment in an era when science often doesn't provide the answers that people desire. He finds that the topic of extraterrestrial life is poisoned by wishful thinking, by the natural human yearning to make contact with our brothers and sisters in space. But ha also finds some fascinating, admirable, and maddening characters who have pursued the truth about extraterrestrial life: Cad Sagan, the brilliant astronomer who brought the cosmos to the masses; Dan Goldin the cantankerous head of NASA who still believes in the dream of the Space Age; Henry Harris, a former Las Vegas lounge singer who is assigned the job of figuring out how to get a spaceship to Alpha Centauri; and various and sundry ufologists, experiencers, spiritualists, and channelers for whom the aliens are an ever-present reality. In this fascinating, funny, and spirited book, Achenbach discovers that the search for life elsewhere leads us on a looping road back to the fundamental questions about life on Earth. To think coherently about extraterrestrial life, we first must come to terms with who we are, why we exist, and what it means to carry around in our cells an evolutionary history that took tour billion years to unfold Achenbach's message is that it is a wonderful and thrilling thing to be a sentient human being -- a creature capable of foolish romanticism -- in a universe that is mostly rocks and gas and dust and empty space.

In these lively and fascinating essays edited by theoretical physicist Jim Al-Khalili, 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.
