About the Book

From the New York Times 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.

Critical Praise

"Interstellar is a deliciously provocative and deeply optimistic book. Avi Loeb invites us to reimagine our place in the universe, confront urgent questions about our future, and remember that scientific curiosity is key to our survival.” — Daniel H. Pink, #1 New York Times bestselling author of Drive and The Power of Regret

“In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system. Part graceful memoir and part plea for keeping an open mind about the possibilities of what is out there in the universe—in particular, life. Loeb is one of the more imaginative and articulate scientists around. . . . Half memoir, half soaring monologue.”  — New York Times on Extraterrestrial

“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 on Extraterrestrial

"Well-written and compelling."  — Forbes on Extraterrestrial

"Loeb makes a persuasive scientific argument about ‘Oumuamua’s otherworldly origins."  — New York magazine on Extraterrestrial

“A tantalizing, probing inquiry into the possibilities of alien life.”  — Kirkus Reviews on Extraterrestrial

“Is humanity prepared to meet its neighbors? In this brilliant, provocative, and beautifully-written book, leading astronomer and extraterrestrial evangelist, Avi Loeb, says we better get ready—and soon. So buckle up and start reading!”
— Daniel Gilbert; Edgar Pierce Professor of Psychology, Harvard University; author of the New York Times best-seller Stumbling on Happiness
