Using a potent NASA space telescope to scan the skies for planets like ours where life might exist, astronomers said Thursday they have found the most Earth-like candidates yet.
This artist's concept provided by NASA April 18, 2013, depicts Kepler-69c, a super-Earth-size planet in the habitable zone of a star like our sun, located about 2,700 light-years from Earth in the constellation Cygnus. Kepler-69c, is 70 percent larger than the size of Earth, and is the smallest yet found to orbit in the habitable zone of a sun-like star.
Two of the five planets orbiting a sun-like star called Kepler-62 are squarely in what astronomers call the habitable zone -- not too hot, not too cold and possibly bearing water, researchers said in the journal Science.
