NASA's Kepler Finds 2 Most Earth-Like Planets To Date
While the eight planet discoveries announced Tuesday are in the habitable range, two are considered the most Earth-like found to date.By Cliff Judy | January 7, 2015
This planet, spotted by the Kepler spacecraft, might be one of the most Earth-like planets ever found by NASA. The space agency announced eight newly found planets in habitable zones where liquid water could exist on the planet's surface, two of those being "the most similar to Earth of any known exoplanets to date." Yes, we know NASA's said that before.
But Kepler's whole mission is, after all, to find Earth-like planets. The eight announced Tuesday at the American Astronomical Society's winter meeting in Seattle brought Kepler's number of confirmed exoplanets discovered to more than 1,000. (Video via NASA)
NASA launched Kepler in 2009, and the spacecraft detects possible planets by monitoring starlight. If something moves in front of a star and dims what Kepler can see, it could be an orbiting planet. (Video via NASA)
