Distant Wanderers: The Search for Planets Beyond the Solar System [Hardcover]

Bruce Dorminey does an excellent job of setting the stage. For the layman, like me, there are simple explanations of the more technical terms and concepts. These are welcome and wisely placed within the text, making the book highly readable. The professional merely skips over these italicized paragraphs.

As he travels the world to visit observatories, scientists and their scientific conferences, Mr Dorminey adds his own observations of the localities, the technical facilities and the personalities behind some of these remarkable discoveries. Amongst others, we follow him to Chile, Hawaii, the south of France and even the Isle of Capri!

The final chapters on Signatures of Life and Signals of Life are what this search is all about. Fascinating reading!

It is enjoyable and well worth the time to read this well written book on a truly absorbing subject.

In Distant Wanderers, Bruce Dorminey looks at the history, methods, and future of extrasolar planet hunting. He predicts, "Before the end of this new century, every schoolchild will know for certain how many planers circle nearby stars," and whether or not Earth-like planets are a rare anomaly. Like many rapidly developing scientific fields, the search for extra-solar planets has had many controversies and false starts along with the startling new discoveries, and the book presents a variety of theories and viewpoints in a fair and even-handed way.

In the first part of the book, Dorminey, an award-winning science journalist and former bureau chief for Aviation Week & Space Technology, describes methods that planet hunters have used (spectroscopic methods, astrometric detection, interferometry, microlensing, transit studies, and direct imaging through the use of a coronagraphic mask in the focal plane a camera). Although most of these methods require sophisticated technology and painstaking analysis, he explains each term or concept as it is introduced. He makes the science seem simple enough for lay readers to grasp and explains the strengths and limitations of each method.

The rest of the book looks ahead to programs that are planned for the future, including telescopes in space and larger, more sophisticated instruments here on Earth. Some of these programs are already funded and will begin soon. Others are nd ambitious ideas that may not be attempted for years, if they ever happen at all.

Dorminey explains current ideas about formation of planets and discusses the search for Earth-like planets and for chemical signatures of extraterrestrial life. Through interviews with numerous researchers and experts, he presents information on what has already been learned about extrasolar planets and gives readers a feeling for the personalities and activities involved in doing this kind of research. In the process of writing Distant Wanderers, Dorminey himself wandered to far-off places, meeting the scientists and visiting the telescopes that are searching for extrasolar planets. His reports on his travels make the book much more human, interesting, and also tell us something about the writer.

After a visiting the European South Observatory's Very Large Telescope (VLT) in Chile's Atacama Desert, Dorminey wrote, "After a night on an observatory mountain, E-mails left unanswered and faxes gone missing seem trivial indeed. I knew that a thousand miles south and several thousand miles north, the world was racing hither and yon. But for me, at that moment, my own existence seemed as precarious as the shallow atmosphere separating us from the nothingness beyond. If only for a fleeting minute, it was impossible not to imagine Earth as it really is: an oasis in the midst of a relative void."

Perhaps you can't quit your day job to make a grand tour of observatories. If that's the case, buy this book and read it. I learned and enjoyed. So will you.
