"The views expressed here range from the cautious to the radical, and from those rooted in hard science to the more fanciful, and the views on extraterrestrial life range from those who see it as being widespread, to those who suspect it is extremely rare, perhaps unique to Earth. There is absolutely no comfort in this book for believers in extraterrestrial UFOs, or extraterrestrial humanoids." - Magonia Review of Books, September 2010
"Chris Impey's concept for the compilation of real-life conversations with astrobiological academics and professionals is unique and, at times, fascinating. He must be applauded for the evident effort in conducting and putting together nearly forty broad ranging interviews." - Leila Battison, Astrobiology Society of Britain
Containing candid interviews with dozens of astronomers, geologists, biologists, and writers about the origin and range of terrestrial life and likely sites for life beyond Earth, this book will fascinate anyone who has ever wondered 'Are we alone?'
