Alien Oceans: The Hidden Water Worlds That Could Be Harboring Life Right Now

By Marcus Veylan

Beneath the ice of Jupiter's moon Europa lies an ocean twice the size of all Earth's seas combined.

On Enceladus, a tiny moon of Saturn, hundreds of geysers are actively spraying the contents of a hidden ocean directly into space. Right now. While you read this.

We are not looking for little green men anymore.

ALIEN OCEANS is the definitive guide to the most exciting scientific frontier of our time - the discovery that our solar system is teeming with liquid water, and that the conditions for life exist in places we never thought to look.

Acclaimed science writer Marcus Veylan takes you on a journey through the hidden water worlds of the solar system and beyond, revealing:

Why Europa's buried ocean - in permanent darkness, under miles of ice - may be the most habitable place beyond EarthHow Enceladus is already showing us its ocean chemistry through plumes we can fly through and analyse right nowWhat Titan's methane seas, rivers, and rain tell us about life using entirely different chemistryWhy the deep-sea vents of Earth's own oceans are our best model for what alien life might look likeThe missions already on their way - and the instruments being built to detect life in an ocean we cannot seeWhat finding microbial life beyond Earth would mean for science, philosophy, and our understanding of everything

Drawing on the latest discoveries from NASA's Europa Clipper, the Cassini mission's extraordinary Enceladus data, and the emerging field of ocean world astrobiology, ALIEN OCEANS is a book about the most important question the human species has ever asked.

Are we alone?

The answer may already be swimming in the dark.
