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 it only looked in a tiny part of the galaxy.
Kepler scientist Mario Perez says that means that “we are probably not alone” because four years of data show how common Earth-like planets can be. Outside scientists agreed that this is a boost in the hope for life elsewhere.
NASA says several of the 10 new potentially habitable planets circle stars similar in size to our sun.
NASA also announced 219 new planets.
