"""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."" -- Kim Stanley Robinson, author of The Ministry for the Future and the Mars trilogy ""In this provocative new book, Adam Frank makes the case that one good way to think about life on Earth is to think about the prospect of life on other planets--and what it might have to teach us about how to be good Earthlings."" -- Sean Carroll, author of Something Deeply Hidden, on Light of the Stars ""A valuable perspective on the most important problem of our time."" -- Adam Becker, NPR, on Light of the Stars ""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."" -- Annaka Harris, New York Times bestselling author of Conscious: A Brief Guide to the Fundamental Mystery of the Mind"
