Considering the development of life on Earth, the existence of life in extreme environments and the potential for life elsewhere in the Universe, this book gives a fascinating insight into our place in the Universe. Chris Impey leads the reader through the history, from the Copernican revolution to the emergence of the field of astrobiology - the study of life in the cosmos. He examines how life on Earth began, exploring its incredible variety and the extreme environments in which it can survive. Finally, Impey turns his attention to our Solar System and the planets beyond, discussing whether there may be life elsewhere in the Universe. Written in non-technical language, this book is ideal for anyone wanting to know more about astrobiology and how it is changing our views of life and the Universe. An accompanying website available at www.cambridge.org/9780521173841 features podcasts, articles and news stories on astrobiology.
Publishers Weekly,Until a few years ago scientists believed that habitable zones around stars were fairly narrow. Today, after the discovery of 250 planets around other stars, they have had to reconsider the basic requirements for life and even how to define life. Impey, a noted astronomer at the University of Arizona and observer with the Hubble telescope, takes readers on a journey from the emergence of life on a still bubbling Earth to possible scenarios for our descendants fleeing a dying sun. Impey pays more attention than many writers to the importance of star types and their location in the galactic neighborhood for producing and sustaining planets. He shows how resilient microbes may be able to survive light-year-long journeys huddled deep within meteors and comets, and that we now know that the moons in our solar system alone offer an amazing range of possibly favorable environments for life, from the ice oceans on Jupiter's moons to the methane geology of Titan. Impey makes good use of his extensive teaching background in this carefully laid-out book. Readers with little formal science background will enjoy this wild ride through the ages and deep space as much as will dedicated SETI buffs. B&w illus. (Dec. 11) (c) Copyright PWxyz, LLC.
