In the mid-1990s, astronomers made history when they detected three planets orbiting stars in the Milky Way. The planets were nothing like Earth, however: they were giant gas balls like Jupiter or Saturn. More than 500 planets have been found since then, yet none of them could support life.

Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and MIRROR EARTH unveils their passionate quest.


Mr. Lemonick covered science and the environment for TIME magazine for nearly 21 years, where he wrote more than 50 cover stories, and has also written for Discover, Scientific American, Wired, New Scientist and The Washington Post. Lemonick is the author of four books, and a cover story for TIME was featured in the anthology Best American Science and Nature Writing 2007. He has taught science and environmental journalism at Princeton, Columbia, Johns Hopkins and New York Universities. He holds a Master of Science in Journalism from Columbia University.
