Where would you look for alien life? An astronomer and science popularizer explains the basics of astrobiology to outline five plausible scenarios for finding extraterrestrials

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy.
Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks readers to imagine—and choose among—five scenarios for finding life. He encourages us to wonder whether life might exist within Mars’s subsoil ice. He reveals the vital possibilities on the water-ice moons Europa and Enceladus. He views Saturn’s moon Titan through the lens of our own planet’s ancient past. And, he even looks beyond our solar system, investigating the top candidates for a “second Earth” in a myriad of exoplanets and imagining the case of a radio signal arriving from deep space. Covering the most up-to-date research, this accessibly written book provides readers with the basic knowledge necessary to decide where they would look for alien life.

An active researcher in the fields of cosmology and the evolution of galaxies, Jon Willis is associate professor of astronomy at the University of Victoria in British Columbia, where he teaches a popular course on astrobiology.

"[Jon Willis] conveys great enthusiasm alongside necessary scientific skepticism."—Wall Street Journal

"Energizing. . . . Through humorous, concise, accessible writing, Willis eloquently presents the growing—though still circumstantial—evidence that we are not alone."—Publishers Weekly (starred review)

"Expert, measured and drily humorous, Willis is an excellent guide to the lunar environments that may, just conceivably, be harbouring microscopic life. . . ."—Tom Holland, Spectator

"Each chapter is authoritative, accessible and fun, and together they form a skillfully executed and entertaining book."—Alastair Gunn, BBC Sky at Night

"All These Worlds Are Yours is unashamedly popular, but tells a coherent story. . . . Willis provides an impressively concise and reasonably accurate account of the place of the Earth and solar system in the universe, then concentrates on the chances of finding extra-terrestrial life among the Sun’s family of planets."—John Gribbin, Literary Review

"All These Worlds Are Yours is a serious but accessible examination of the prospects for finding life elsewhere in the universe. From the solar system to planets around other stars, this is a lively guidebook for where life could be and how we can go about looking for it."—Sean Carroll, author of The Big Picture: On the Origins of Life, Meaning, and the Universe Itself

"Jon Willis has written an engaging primer on astrobiology that is both comprehensive and conversational. All These Worlds Are Yours covers everything under the sun—and far beyond—about the hunt for alien life."—Lee Billings, author of Five Billion Years of Solitude: The Search for Life Among the Stars

"A brilliantly written summary of the classical work on the chemistry of life, and the latest results in the exploration of moons and planets within, and the search for planets without, our Solar System."—Steven Benner, author of Life, the Universe, and the Scientific Method
