NASA confirms 715 planets outside solar system

Suddenly we're rolling in planets.

Wednesday, scientists confirmed discovery of a whopping 715 new planets orbiting stars other than our own sun, nearly doubling the number of such planets on the books. Researchers have trumpeted the discovery of large batches of unconfirmed candidate planets outside the solar system but never before have so many genuine, verified "exoplanets," as they're known, been reported at once.

"What we've been able to do … is strike the mother lode, get a veritable exoplanet bonanza," planetary scientist Jack Lissauer of the NASA Ames Research Center said at a news briefing.
