Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe.

We’ve long been led to believe that astronomers spend every night searching the sky for extraterrestrials, but the truth is we have barely started looking. Not until now have we even known where to look or how. In The Little Book of Aliens, Frank, a leading researcher in the field, takes us on a journey to all that we know about the possibility of life outside planet Earth and shows us the cutting-edge science that has brought us to this unique moment in human history: the one where we go find out for ourselves.

Shermer and Frank discuss: origin of Life • Drake Equation • Fermi’s Paradox • UFOs and UAPs • Projects Sign, Blue Book, Cyclops, Grudge • AATIP (Advanced Aerospace Threat Identification Program) • Alien Autopsy film • SETI & METI • technosignatures & biosignatures • aliens: biological or AI? • convergent vs. contingent evolution • interstellar travel • Dyson spheres, rings, and swarms • Kardashev scale of civilizations • aliens as gods and the search as religion • why aliens matter.

Adam Frank is the Helen F. and Fred H. Gowen Professor in the Department of Physics and Astronomy at the University of Rochester. A Carl Sagan Medal winner from the American Astronomical Society, he is also the author of Light of the Stars and was the science advisor for Marvel’s Doctor Strange. Frank is the principal investigator on NASA’s first grant to study technosignatures — signs of advanced civilizations on other worlds — and his current work focuses on the evolution of life and planets, the “Astrobiology of the Anthropocene,” and the long-term trajectory of civilizations.
