Where did we come from? Are we alone? Where are we going? These are the questions that define the field of astrobiology. New discoveries about life on Earth, the increasing numbers of extrasolar planets being identified, and the technologies being developed to locate and characterize Earth-like planets around other stars are continually challenging our views of nature and our connection to the rest of the universe. In this book, philosophers, historians, ethicists, and theologians provide the perspectives of their fields on the research and discoveries of astrobiology. A valuable resource for graduate students and researchers, the book provides an introduction to astrobiology, and explores subjects such as the implications of current origin of life research, the possible discovery of extraterrestrial microbial life, and the possibility of altering the environment of Mars.

"The scientists and engineers who work on the Mars exploration program should read this book, especially on the ethical questions regarding the terraforming of the planet Mars. This book is also an interesting read for the general public, who are mildly interested in the origin of life and in search for extraterrestrial life, or even for people who have been searching for God in their personal endeavors." The Leading Edge
"...this volume is the product of a largely unprecedented and laudable collaboration between scientific and philosophical disciplines in approaching the growing field of astrobiology. Regardless of the readers' specialisation, this is an important 'turn-to' book for academic discussion on the inevitable philosophical, ethical and religious questions surrounding the search for life in the universe." - Leila Battison, Astrobiological Society of Britain
