Finding Another Earth
Pasadena CA (JPL) Jul 27, 2015
The discovery of a super-Earth-sized planet orbiting a sun-like star brings us closer than ever to finding a twin of our own watery world. But NASA's Kepler space telescope has captured evidence of other potentially habitable planets amid the sea of stars in the Milky Way galaxy. To take a brief tour of the more prominent contenders, it helps to zero in on the "habitable zone" around their stars. This is the band of congenial temperatures for planetary orbits - not too close and not too far. Too c ... read more
