NASA: Kepler Finds Earth-like Planet

Astronomers with NASA’s Kepler mission have confirmed the existence of an Earth-like planet in a “habitable zone” around a star not unlike our own.

The planet, Kepler 22-b, lies about 600 light years away, about two-and-a-half times the size of Earth, with a temperature of about 22 degrees Celsius, allowing liquid water to exist on the surface. Its year is about 290 days long. This is the first time the Kepler mission has detected a potentially habitable world orbiting a Sun-like star, scientists reported in findings to be published in The Astrophysical Journal.
