Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left 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 controversial theory and its profound implications: for science, for religion, and for the future of our species and 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 world's leading alien hunter" -- New York Times Magazine From acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars. In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar? Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, 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, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.

More of Isaac Asimov's weekly science columns for the Los Angeles Times and those his wife, Janet, wrote during his illness and after his death in April 1992. The Asimovs discuss how close we are to producing life in a lab, the latest revelations about dinosaur extinction, recent startling sightings of planets and stars, if we can establish colonies on Mars, if computer intelligence can ever surpass human intelligence, and the gravest dangers to our environment.
