We Are Not Alone: Why We Have Already Found Extraterrestrial LifePaperback, 1 May 2011

Extraterrestrial life exists and there is evidence to prove it.

The book that ignited the astronomy community has come back for everyone else

This groundbreaking book demonstrates that between the results of the 1976 Viking I lander and the latest scientific discoveries - from fertile Martian soil to microbe-ridden meteorites - there is a powerful case for life on the Red Planet and beyond. Taking weird organisms on Earth as a starting point, Schulze-Makuch and Darling explore what forms extraterrestrial life might take and where it may reside. From the noxious clouds of Venus to the methane rains of Titan, We Are Not Alone provides a captivating tour of the Solar System and shows that it's much more crowded than we previously realised.
