The Kepler telescope that is kept at NASA has found 503 new planets, some of which may be habitable. The telescope detects tiny brightness dips that are caused when the planets pass in front of their stars’ faces.
‘Some of these new planet candidates are small and some reside in the habitable zone of their stars, but much work remains to be done to verify these results… The latest finding brings Kepler`s tally of exoplanet candidates to 3,216… The new haul was pulled from observations Kepler made during its first three years of operation, from May 2009 to March 2012. The telescope has not done any planet hunting since being hobbled by a failure in its orientation-maintaining system last month’, said researchers
