'LOEB IS AN ASTRONOMICAL SHERLOCK HOLMES' Washington Post 'A JOY IN CONJECTURE AND AN OMNIVOROUS SPIRIT OF INQUIRY. . . CARL SAGAN WOULD HAVE LIKED THIS BOOK' The Times In 2017, Avi Loeb, Chair of Harvard's Astronomy Department, went public with a theory that shook the scientific community - our solar system has been visited by advanced alien technology. His provocative and persuasive argument (and internationally bestselling book Extraterrestrial) has opened thousands of minds to the existence of intelligent life beyond Earth. This book tackles the huge question of what happens next? Long the stuff of science-fiction, here at last is the science fact. From advances in deep space probes to ongoing searches for extraterrestrial technology in our night sky, through the latest heated debates over the existence of Unidentified Aerial Phenomena, Interstellar offers a thrilling, front-row view of the technology and the ideas currently preparing us for contact with alien civilizations. Providing the first realistic and practical blueprint for how that might actually occur, Professor Loeb lays out the profound implications of our becoming - or not becoming - an interstellar species. In an urgent, eloquent appeal for more proactive engagement with the outer universe, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe. Combining cutting-edge science, physics, and philosophy, Loeb takes us on a mind-bending journey through the furthest reaches of science, space-time, and the human imagination. Interstellar is an eye-opening, necessary look at our future that proves, once again, that scientific curiosity offers the key to our survival. 'Loeb is surely correct. . . scientists studying the vastness of the cosmos should entertain risky ideas more often, for the universe is undoubtedly more wild and unexpected than any extremes conjured by the human imagination' Economist 'A COMPELLING ARGUMENT FOR A MORE OPEN-MINDED APPROACH TO SCIENCE - A COMBINATION OF HUMILITY AND WONDER' New Statesman

This roadmap, released in early 2014, presents a science-driven 30-year vision for the future of NASA Astrophysics that builds on recent remarkable discoveries to address three defining questions: Are we alone? How did we get here? How does the universe work? Enduring Quests * Are We Alone? * The Exoplanet Zoo * What Are Exoplanets Like? * The Search for Life * Activities by Era * How Did We Get Here? * Stellar Life Cycles and the Evolution of the Elements * The Archaeology of the Milky Way and Its Neighbors * The History of Galaxies * Activities by Era * How Does Our Universe Work? * The Origin and Fate of the Universe * Revealing the Extremes of Nature * Listening to the Cosmos * Activities by Era * Public Engagement: Connecting Through Astronomy * The continuum of astronomy learners * Audiences: From online to one-on-one * Realizing the Vision: Notional Missions and Technologies * Formative Era * The Visionary Era * Cross-cutting, Game-changing Technologies * Science Summary * Technology Summary * Daring Visions * Acronyms Seeking answers to these age-old questions are Enduring Quests of humankind. The coming decades will see giant strides forward in finding earthlike habitable worlds (exoEarths), in understanding the history of star and galaxy formation and evolution, and in teasing out the fundamental physics of the cosmos. * Different astronomical phenomena are typically most prominent in distinct regions of the electromagnetic spectrum: young, dust-enshrouded stars in the far-infrared; older stars and galaxies in visible and near-optical wavelengths; star-forming regions in the ultraviolet, and the million-degree gas of galaxy clusters and black hole accretion disks in X-rays. In addition to spanning the electromagnetic spectrum, the roadmap missions will open a revolutionary new window on the cosmos by detecting gravitational waves, ripples of space-time that emanate from colossal events like the merging of two black holes. These scientific investigations and their enabling space missions are described here in three broad categories of time: the Near-Term Era, defined by missions that are currently flying or planned for the coming decade; the Formative Era, with notional missions (referred to here as "Surveyors") that could be designed and built in the 2020s; and the Visionary Era of technologically advanced missions (referred to as "Mappers") for the 2030s and beyond. The past three decades have seen prodigious advances in astronomy and astrophysics. We have discovered thousands of planets around other stars, revealing a startling diversity of planetary systems and demonstrating that our own solar system is one of many billions across the galaxy. We have mapped the life cycle of stars from their formation in nearby stellar nurseries to their sometimes explosive deaths. We have tallied supermassive black holes weighing millions to billions of times the Sun's mass, finding them in the centers of most big galaxies, where they gorge on gas and stars and blast superheated material into their environments. We have traced the growth and transformation of galaxies from young chaotic shreds a billion years after the Big Bang to the majestic forms they display today. We have established, using precision cosmological measurements, a well-tested account of the Big Bang model's underlying physics. The current picture points to a universe where an early epoch of inflation established uniformity over a vast horizon, where dark matter dominates the gravitational forces that provide the underlying framework of cosmic structure, and where dark energy drives expansion at an ever-accelerating rate.

'VISIONARY' Stephen Greenblatt 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.

In The Earth as a Distant Planet, the authors become external observers of our solar system from a distance and try to determine how one can understand how Earth, the third in distance to the central star, is essentially unique and capable of sustaining life. The knowledge gained from this original perspective is then applied to the search for other planets outside the solar system, or exoplanets. Since the discovery in 1992 of the first exoplanet, the number of planet detections has increased exponentially and ambitious missions are already being planned for the future. The exploration of Earth and the rest of the rocky planets are Rosetta stones in classifying and understanding the multiplicity of planetary systems that exist in our galaxy. In time, statistics on the formation and evolution of exoplanets will be available and will provide vital information for solving some of the unanswered questions about the formation, as well as evolution of our own world and solar system. Special attention is paid to the biosignatures (signs of life) detectable in the Earth's reflected spectra and the search for life in the universe. The authors are experts on the subject of extrasolar planets. They provide an introductory but also very much up-to-date text, making this book suitable for researchers and for advanced students in astronomy and astrophysics.

Barrie Jones addresses the question "are we alone?", which is one of the most frequently asked questions by scientists and non-scientists alike. In The Search for Life Continued, this question is addressed scientifically, and the author is not afraid to include speculation. Indeed, the author believes beyond reasonable doubt that we are not alone and this belief is based firmly on frontier science of the most imaginative kind. The author concentrates on planetary systems beyond our own but starts with life on Earth, which is the only life we know to exist, and which provides guidance on how best to search for life elsewhere. Planets are the most likely abode of life and so we start the quest with the search for planets beyond the Solar System – exoplanets. The methods of searching are outlined and the nature of hundreds of exoplanetary systems so far discovered described. In the near future we expect to discover habitable Earth-like planets. But are they actually inhabited? How could we tell? All will be revealed. This full color book is written for everybody who wants to stay in close contact with the latest on possible life on other planets.

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 existed 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.
