A step closer to Earth-like planets

Earth- like planets with life-sustaining conditions are spining around stars in the galaxy of our neighbourhood but they have not been found yet, told by US astrophysics.
There are few dozen solar-type stars whih are 30 light years of the sun- half of them have Earth-like-planets.One light year equals the distance light travels in one year at the speed of 300,000 kms per sec.
US astrophysics are convinced that the Earth-sized planets could be found either by the Kepler space telescope US space agency NASA plans to launch on March 5, or by the French-European telescope equipment COROT satellite that has been in orbit since 2006.
