PDF-(DOWNLOAD)-Strange New Worlds: The Search for Alien Planets and Life beyond Our Solar

Soon astronomers expect to find alien Earths by the dozens in orbit around distant suns Before the decade is out telltale signs that they harbor life may be found If they are the ramifications for all areas of human thought and endeavorfrom religion and philosophy to art and biologywill be breathtaking In Strange New Worlds renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planetsand alien lifebeyond our solar systemOnly in the past fifteen years after millennia of speculation have astronomers begun to discover planets around other starshundreds in fact But the hunt to find a true Earthlike world goes on 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 findingsincluding his ownthat 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 Jupiterlike gas giants and superEarthsrocky planets with several times the mass of our own planetand how astronomers use biomarkers to seek possible life on other worldsStrange New Worlds provides an insiders look at the cuttingedge science of todays planet hunters our prospects for discovering alien life and the debates and controversies at the forefront of extrasolarplanet research.
