“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.

Inthe New York TimesbestsellerExtraterrestrial,Avi Loeb, thelongest serving Chair of Harvard’s Astronomy Department, presented a theory thatshook the scientific community: our solar system, Loeb claimed, had likely been visited bya 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 ofintelligent 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,Interstellarprovides 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, Loebprovides a thrilling, front-row view of the monumental progress in science and technologycurrently preparing us for contact. He also lays out theprofound implications of becoming—or not becoming—interstellar; in an urgent, eloquent appeal for more proactive engagementwith 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 edgescience, physics, and philosophy,Interstellarrevolutionizes the approachto our search for extraterrestriallife 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.
