NASA makes exciting discovery

NASA announced some exciting news Monday morning. It says it has discovered a new planet in a habitable zone.

That means water can exist on this planet, which in turn means life could potentially exist.

Check out the video to see a NASA graphic of the planet.

They call it Keplar-22-B.

NASA says the planet is orbiting a star similar to our sun.

The planet is nearly two-and-a-half times the size of our earth, and it's about 600 light-years away.
