Envisioning Exoplanets traces the journey of astronomers and researchers on their quest to explore the universe for a planet like Earth. Exoplanets — worlds beyond our solar system — were once dismissed as science fiction. Now, with more than 4,000 confirmed exoplanets, countless possibilities exist for what remains to be uncovered in the universe. This book follows the exhilarating progression of exoplanet research from its earliest stages operating on the fringes of scientific research to the newest developments of renowned agencies around the world searching for planets capable of hosting life. Featuring provocative questions about the universe and more than 200 remarkable illustrations from Michael Carroll, Ron Miller, and other key members of the International Association of Astronomical Artists, Envisioning Exoplanets is an intergalactic visual voyage.
