IMAGINED LIFE: A Speculative Journey among the Exoplanets in Search of Intelligent Aliens, Ice Creatures, and Supergravity Animals
by James Trefil & Michael Summers
September 2019 – Smithsonian Books (US)
The captivating possibilities of extraterrestrial life on exoplanets, based on current scientific knowledge of existing worlds and forms of life.
It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists 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.
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. 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.
Exoplanets are a major emerging field of study, and new ones are discovered every day. This book taps into burgeoning interest in the possibilities they present for extraterrestrial life. IMAGINED LIFE will change the way readers imagine space with incredible new observations and predictions that reshape what we think we know about the universe.
