“With wit and brio, Frank separates current nonsense about aliens from the serious and fascinating search for extraterrestrial life.”

“This wonderful book unravels the tangled ball of humanity’s thinking about aliens, and tells the whole story with high humor and immense clarity. Adam Frank helpfully explains what scientists are doing now to explore the galaxy remotely in search of answers to this fascinating mystery. Read this and you’ll know as much as anyone does on the topic— it’s as clear as a map, as clear as Drake’s Equation. ”

“From the details of the origins of life on Earth, to the physics (and hypothetical future physics) of interstellar travel, The Little Book of Aliens is a comprehensive exploration of the seemingly limitless potential of intelligent life, human and beyond. Frank’s book is science writing at its best, revealing the awe-inspiring capacity of science to help us understand, and navigate, the universe. ”

“Aliens and UFOs have held perennial fascination for us all. Now, Adam Frank gives us an entertaining romp through our quickly changing attitudes to these topics. In just the last decade, biologists have achieved genuine insights into life’s origin, and astronomers have discovered thousands of ‘exoplanets’ orbiting distant stars. At last, we understand what to look for and where, and Adam Frank has written it down for us.”

“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.”

“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.”

“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.”
