Strange New Worlds

The Search for Alien Planets and Life Beyond Our Solar System

Description

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars--thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own--that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds.

Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research.

In a new afterword, Jayawardhana explains some of the most recent developments as we search for the first clues of life on other planets.

From Publishers Weekly

Feb 28, 2011 – Popular astrophysicist Jayawardhana (Star Factories) suggests that mankind may be on the brink of a new scientific revolution. In the last two decades, "after millennia of musings and a century of false claims, astronomers have finally found definitive evidence of planets around stars other than the Sun." Within our lifetime, the author argues, scientists may discover the existence of life on one or more of these celestial bodies. He takes the reader on a four-century-long scientific quest to discover our place in the universe, beginning with the Copernican hypothesis and Galileo's discovery of four of Jupiter's moons. More recently, astronomer Debra Fischer's discovery of the existence of three planets orbiting a pair of twin stars widened the field of possibilities. While the criteria for the presence of life are stringent indeed, there are countless new possibilities, and Jayawardhana reviews technological advances from Galileo's primitive telescope to the Hubble, and the development of computerized adaptive optics, that allow today's astronomers to better probe the universe. The author also introduces the new science of astrobiology, which uses spectral analysis to seek evidence of life. An exciting, highly readable glimpse into a discovery that could have broad scientific and cultural implications.
