NASA Discovery: 7 Earth-Sized Planets

Scientists from NASA announced on February 22 that they have discovered seven planets orbiting a nearby star. The planets are all about the same size as Earth, and three of them are in what scientists call the “habitable zone.”

(The habitable zone is the area of space around a star where a planet is most likely to have liquid water on its surface. Scientists believe water is necessary for anything to live on a planet.)
