“The Pale Blue Data Point is goosebump inducing. Willis grapples with deep questions about our place in the universe, and readers may be astonished to learn that the answers could be breathtakingly close at hand.”

Lee Billings, author of "Five Billion Years of Solitude: The Search for Life Among the Stars"

“Willis’s book is quite novel: He shows how the search for life in the cosmos is guided by our studies of life on Earth. And he does so with anecdotes of his own travels to experience the different Earth-bound investigations—of life in hydrothermal vents, fossilized bacteria, exoplanets, traces in meteorites, and more—which makes the book extremely fun. An enlightening read (even as a physicist), The Pale Blue Data Point is a charming, compelling, and approachable look at how scientists are hunting beyond the Earth for life unknown to us.”

Gregory J. Gbur, author of "Falling Felines and Fundamental Physics" and "Invisibility: The History and Science of How Not to Be Seen"

“A lively introduction to the field of astrobiology.”

The New York Times Book Review, on "All These Worlds Are Yours"

“[Willis] conveys great enthusiasm alongside necessary scientific skepticism.”

The Wall Street Journal, on "All These Worlds Are Yours"

“Energizing. . . . Through humorous, concise, accessible writing, Willis eloquently presents the growing—though still circumstantial—evidence that we are not alone.”

Publishers Weekly (starred review), on "All These Worlds Are Yours"

“A concise overview of astrobiology and what we know—and, more importantly, what we don’t—about the search for life elsewhere in our solar system and beyond.”
