Scientists see potential for ‘another Earth’ among 3 newly discovered exoplanets
NASA’s Kepler Space Telescope has recently discovered a star with three planets only slightly larger than Earth that can help study the atmosphere of the earth-size worlds , which may provide proof of potential alien life.
The outermost planet orbits in the “Goldilocks” zone, a region where surface temperatures could be moderate enough for liquid water and perhaps life, to exist.
