Life as We Do Not Know It: The NASA Search for (and Synthesis of) Alien Life

An engrossing and revelatory first look at the search for alien life—on Earth and beyond

For the past twenty years, Peter Ward has been at the forefront of popular science writing, with books such as the influential and controversial Rare Earth. In Life as We Do Not Know It, Ward, with his signature blend of eloquence, humor, and learned insight, vividly details the latest scientific findings, cutting-edge research, and intrepid new theories on the subject of alien life and the possible extraterrestrial origins of life on Earth. In lucid, entertaining, and bold prose, Peter Ward once again challenges our notions of life on earth (and beyond).

Peter Ward, a recognized authority on mass extinctions, is professor of Earth and Space Sciences at the University of Washington in Seattle. His books include Gorgon, Future Evolution, The End of Evolution, and, with Donald Brownlee, Rare Earth and The Life and Death of Planet Earth. He has also appeared in numerous TV documentaries for PBS, Discover, and The Learning Channel.
