WASHINGTON- The planet-hunting Kepler telescope shows that our galaxy is far more crowded with the discovery of 715 new planets outside the solar system.
Scientists have doubled the number discovered in the galaxy to about 1,700 with the help of Kepler. NASA says astronomers used a new confirmation method to come up with the largest batch of planets to be announced at one time.
All of the newly discovered ones are in systems like our own where multiple planets are in what's called "Goldie Locks Zones" that aren't too hot or too cold. Twenty years ago astronomers hadn't found any planets circling stars other than our sun.
