Are We Alone?

     by Dimitar Sasselov 

Intended for general readers, this volume on the history and possibilities of astronomical and biochemical research examines the study of super-earths, distant planets similar to earth that allow scientists to study how earth may have been millennia ago. Sasselov (astronomy, Harvard U.) explores the implications of these discoveries for biological research in chapters which discuss both the study of extraterrestrial bodies and the search for the origins of life on earth.

Life of any kind has yet to be found anyplace except on the Earth.  However, within the last few years astronomers have found over 3000 exoplanet candidates.  In December the Kelper satalite teleoscope found two earth sized planets orbiting sun like stars.  The planets were not in the sun's habitable zone.  This book has the cutting edge information on the search for alien worlds.
