This artist rendering provided by NASA/JPL-Caltech shows some of the 219 new planet candidates, 10 of which are near-Earth size and in the habitable zone of their star identified by NASA’s Kepler space telescope. NASA says its planet-hunting telescope has found 10 new planets outside our solar system that are likely the right size and temperature to potentially have life on them. As the Kepler telescope finished its main mission, NASA announced Monday that it has seen a total of 49 planets in the “Goldilocks Zone” for possible life. And they only looked in a tiny part of the galaxy. (NASA/JPL-Caltech via AP)
