Neil deGrasse Tyson urges alien‑contact preparedness in new book

Astrophysicist Neil deGrasse Tyson says humanity should think seriously about how to respond if extraterrestrials ever make contact. He argues the discussion should move from sensationalism to scientific reasoning, using universal constants such as mathematics and the periodic table as a common language. Tyson warns against assuming human customs—like handshakes—will translate and advises leaving habits behind until alien behavior is understood.

His remarks come amid renewed public interest sparked by the release of more than 160 U.S. government UFO documents and recent congressional hearings on unidentified anomalous phenomena. Tyson’s new book, Take Me to Your Leader: Perspectives on Your First Alien Encounter, offers a “road‑map” for first contact, blending scientific insight with cultural references and emphasizing that any alien civilization would likely be far more advanced than humans. The book was published by Simon & Schuster’s new imprint and reflects Tyson’s view that the thought experiment has value even if contact never occurs.
