• Scientists and their Kepler spacecraft have discovered for the first time a planet in distant space that is much like Earth, circling a sun-like star and lying in a region neither too hot nor too cold for an atmosphere that could support some form of life.

  • The temperature on that planet, the scientists say, probably is a comfortable 72 degrees, rain or shine.

  • Dubbed Kepler 22b, the planet exists in what astronomers call the habitable zone of a solar system at whose center is a star only a little smaller and fainter than Earth's sun. It lies about 600 light-years away and is 2.4 times Earth's size, although its mass is still unknown

  • Kepler 22b circles its sun every 290 days, compared with Earth's year of 365 days, the Kepler team has determined
