The Little Book of Aliens

"Adam Frank has written a page-turner on the search for intelligent life in the universe. As informative as it is entertaining, this book ruthlessly falsifies common irrational beliefs about alien existence, but also joyously describes the fascinating current state of serious scientific research on the subject." - Scott Derrickson, director of Marvel Studio's Doctor Strange

"The Little Book of Aliens is not little at all. Its scope is vast and the questions it answers as well as those it asks are as mind-blowing as they are essential. Here you will learn what modern science has to teach about life in the universe from a true master, who is knowledgeable, clear, patient, generous, and really funny. If aliens do land on Earth one day, I hope they choose Adam Frank's backyard. They will be up for an awesome first encounter with a first-rate scientist and human being."
- Marcelo Gleiser, author of The Dawn of a Mindful Universe: A Manifesto for Humanity's Future, and 2019 Templeton Prize laureate

"The Little Book of Aliens is a captivating guide. With a chatty mix of wit and wisdom, Adam Frank comprehensively covers a wide range of topics from historical details to claims of modern-day sightings, while shedding light on our enduring fascination with the concept of aliens."
- Sara Seager, professor of planetary science and physics at MIT, author of The Smallest Lights in the Universe

"An irreverent, expert, and characteristically 'frank' overview of all things aliens, from the Drake Equation to UFOs to warp drive. This is a whirlwind tour from Roswell to the James Webb Space Telescope that stays firmly rooted in physics and the scientific method." - Jason T. Wright, professor of astronomy and astrophysics and director of the Penn State Extraterrestrial Intelligence Center

"Full of the excitement of the scientific enterprise! At the bottom of this engaging book is the profound question: Are we alone in the universe? In clear and accessible writing, Professor Frank provides a critical history of the belief in aliens and their conjectured visitations to Earth, and discusses the methods scientists are using now to search for extraterrestrial life." - Alan Paige Lightman, physicist and author of Einstein's Dreams and The Accidental Universe

"After years of dreaming about exploring the cosmos for signs of intelligent life, [Frank] and other scientists are on the threshold of a new era of unprecedented discovery in the field of astrobiology.... The book brims with fascinating facts and speculations....Frank advises we look for alien life where it most likely exists: deep space. He also stresses the key point that we have only begun to peer into the universe with instruments capable of breakthrough discoveries, a useful riposte to critics of the effort. Throughout, Frank champions the importance of demanding standards of evidence: 'They are, literally, why science works.'" - Kirkus Reviews

"'Is there anyone out there?' asks University of Rochester astrophysicist Frank in this animated overview of scientists' search for extraterrestrial life.... Frank discusses some of the ways astronomers are currently looking for aliens and hospitable planets, including studying the chemical composition of distant planets' atmospheres by observing how they filter starlight as it passes through... a solid survey of the hunt for life beyond Earth." - Publishers Weekly

"Utilizing just enough hard science and plenty of examples to aid in understanding some of the basics of astrobiology, like Dyson spheres and the Drake equation, Frank has provided the reader with a thorough and exciting front-row seat to the future of searching for life in other worlds." - Booklist
