habitable planets

A few thousand years after humanity perfected its terraforming technology and spread across the stars, creating an empire of planets habitable to them, what once was a great empire has now fallen, and the remnants of humanity and their spider allies are left by themselves on far distant worlds. Then, humanity and their spider allies detect radio fragments from some distant star, and some go in search of the signal's source, hoping to find long-lost cousins from old Earth. What they find is something horrific, something woken by their terraforming technology that should have been left alone.

Describes how scientists are actively studying as many planets as they can, and how many could support life as Earth does, and what other wonderful worlds our technology will find.

"[This book] traces the journey of astronomers and researchers on their quest to explore the universe for a planet like Earth"--Provided by publisher.

"'Goldilocks and the Water Bears' is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe"--Dust jacket.

Presents experts' opinions on the viability of space colonization.

The search for life in other worlds begins with the search for a habitable planet. This book explores the (3z(BGoldilocks Zone,(3y (Ba 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 (3z(Bhabitable(3y (Band what kind of life we might find. Fascinating full-color photographs and artist renderings from NASA illustrate this fascinating hunt.

Describes, in graphic form, the reasons humans may need to leave Earth and inhabit another planet; discusses what has been discovered about living in space; and examines how humans can help keep the environment on Earth safe.
