The National Aeronautics and Space Administration (NASA) announced on Wednesday it has found the largest batch of "Earth-Size, Habitable-Zone Planets" orbiting around a single star, called TRAPPIST-1.
"All of these seven planets could have liquid water — key to life as we know it — under the right atmospheric conditions, but the chances are highest with the three in the habitable zone," said NASA.
