Transcript for NASA Releases New Planet Discovery
Finally tonight here, nasa with a new discovery. A new planet that they say might be the closest thing yet to Earth. What's so similar about it? Here's David Wright. Reporter: In the world of astronomy, this is a holy grail. The nearest thing yet to another Earth. Keppler 452-b, circling a sun, slightly brighter than our own. The discovery announced today, the second big news in a week from nasa. Last week, anything control burst into cheers as nasa's new horizons gave us our first close-up view of Pluto, including an animated flyover of Pluto's icy mountains and plains. Today, this new Earth from the Keppler space telescope launched six years ago. Keppler's mission? To find what astronomers sometimes call goldilocks planets, where conditions might be just right to sustain life. Keppler 452-b is bigger than Earth, it could have water and atmosphere, we just don't know. And it's 1400 light years away, but possibly, some day, a new home. David Wright, ABC news, new York. To be continued. Thank you for watching here on a Thursday night. I'm David Muir. I hope to see you right back here tomorrow.
