Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system.
Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths?Alien Oceansreveals the science behind the thrilling quest to find out.
Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.
Alien Oceansdescribes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
Industry Reviews
"[Alien Oceans] describes why studying Earth's own ocean is a crucial chapter in the quest to explore the shores of extraterrestrial seas."---Nadia Drake, National Geographic
"A thoughtful and thought-provoking treatise on the many facets that are being pursued in our quest to discover new worlds and search for life beyond our atmosphere."---Milbry C. Polk, The Explorers Journal
"Alien Oceans offers a historical look-as well as a peek into the future-at one of the most exciting aspects of space exploration. With the technology at hand, we could determine whether there's life beyond Earth."---Sid Perkins, Science News
"A NASA scientist looks to the water-rich moons of Jupiter and Saturn, such as Europa, Titan, and Enceladus, as promising sites for the search for life beyond the Earth." * Publishers Weekly *
"Alien Oceans successfully straddles a fine line between accessibility and scientific thoroughness. Hand's book is as fascinating as it is optimistic."---Tobias Mutter, Shelf Awareness
"This book would make anyone excited about space. The research presented is thorough and the pictures included are amazing. Hand dives into every aspect of life imaginable."---Rachel Dehning, Manhattan Book Review
"This is a fun, pretty cool book to read. . . . Hand's enthusiasm is clear to see, and he has written an accessible book that takes the general reader along with him to illustrate what we already know about Io, Callisto, Titan, Ganymede and Europa too."---Simon Cocking, Irish Tech News
"To paraphrase Hamlet, there are more things in heaven and Earth than are dreamt in our philosophy. Hand calls on us to probe the depths of alien oceans to discover them. I agree."---Robert Zubrin, National Review
"A book that is likely to prove one of the year's most enthralling first-person accounts of a life in science."---Simon Ings, New Scientist
"What is so captivating about this book is that it isn't just a solid survey of what we've learned in recent decades about the icy moons, but that the narrative is told by an active researcher deeply embedded in these endeavours. Through Hand's eyes we meet many of the key personalities involved and feel the sting of disappointment at cancelled funding or a malfunctioning probe, as well as the soaring excitement of a new discovery."---Lewis Dartnell, BBC Sky at Night Magazine
"The author discusses how we look for and study alien oceans and what the future holds for this increasingly popular field of research. This is a book well suited to the general public, with very accessible prose, and science interspersed with personal anecdotes and witty analogies." * Nature Astronomy *
