By Ray Jayawardhana

In Strange New Worlds, popular astronomer Ray Jayawardhana brings information from front strains of the epic quest to discover planets--and alien life--beyond our sun process. in basic terms long ago twenty years, after millennia of hypothesis, have astronomers all started to find planets round different stars--thousands in reality. Now they're nearer than ever to unraveling far-off twins of the Earth. during this e-book, Jayawardhana vividly recounts the tales of the scientists and the awesome breakthroughs that experience ushered during this notable age of exploration. He describes the newest findings--including his own--that are difficult our view of the cosmos and casting new gentle at the origins and evolution of planets and planetary platforms. He unearths how know-how is quickly advancing to help direct observations of Jupiter-like fuel giants and super-Earths--rocky planets with a number of instances the mass of our personal planet--and how astronomers use biomarkers to hunt attainable lifestyles on different worlds.

Strange New Worlds offers an insider's examine the state-of-the-art technological know-how of latest planet hunters, our clients for locating alien existence, and the debates and controversies on the leading edge of extrasolar-planet research.

In a brand new afterword, Jayawardhana explains essentially the most contemporary advancements as we look for the 1st clues of existence on different planets.
