On July 23, 2015 NASA announced discovery of Kepler 452b, an Earth-like exoplanet, which they dubbed Earth 2.0. Found following a four-year trawl through data from the Kepler exoplanet-hunting space telescope, Kepler 452b is the closest exoplanet yet in its resemblance to Earth. It revolves around its sun-like home star in 380 days at a distance similar to that between Earth and our sun (93 million miles).

Unfortunately, Kepler 452b is a “mere” 1,400 light years away — so you can forget trying to strike up a real-time conversation with any of its intelligent inhabitants. If it does harbor life I have to hope that any sentient lifeforms have taken better care of their home than we earthlings do of our own. Then again, it may be better that the exoplanet hosts only non-intelligent life!

Here’s NASA’s technical paper.
