The captivating possibilities of extraterrestrial life on exoplanets, based on current scientific knowledge of existing worlds and forms of life

In this lively must-read for any space buff, Trefil and Summers bring readers on a marvelous experimental voyage through the possibilities of life--unlike anything we have experienced so far--that could exist on planets outside our own solar system. Their exploration goes far beyond E.T. or little green men: instead the authors posit that a virtually infinite array of life forms could exist on the thousands of newly discovered exoplanets that share our universe.

Life could be out there in many forms: on frozen worlds, living in liquid oceans beneath ice and communicating (and even battling) with bubbles; on super-dense planets, where they would have evolved body types capable of dealing with extreme gravity; on tidally locked planets with one side turned eternally toward a star; and even on "rogue worlds," which have no star at all. Yet this is no fictional flight of fancy: the authors take what we know about exoplanets and life on our own world and use that data to hypothesize about how, where, and which sorts of life might develop.

Given the incredible diversity and variety of exoplanets that we know exist, we can expect a similar, or even higher, level of diversity and variety among the life forms that might evolve on worlds beyond Earth. This fascinating book presents science-based predictions about what sort of creatures we might encounter, should we ever voyage beyond our own solar system. Imagined Life is a must-have for anyone wanting to learn how the realities of our universe may turn out to be far stranger than fiction.
