The search for life in other worlds begins with the search for a habitable planet. This book explores the "e;Goldilocks Zone,"e; a defined area that is perfect for harboring life in our universe. Readers will find out how scientists are finding habitable planets by using terrestrial and orbiting telescopes to search these regions. Readers will also get to know how extreme zones on Earth are helping scientists redefine their concept of "e;habitable"e; and what kind of life we might find. Fascinating full-color photographs and artist renderings from NASA illustrate this fascinating hunt.
