NASA’s Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.

NASA's Kepler spacecraft has discovered two Saturn-sized planets transiting the same sun-like star. The same system might contain a third world–a hot "super-Earth" one and a half times the size of Earth–but this is not yet confirmed. Researchers announced the results today at a NASA press conference.

NASA’s Kepler Mission has released 43 days of science data on more than 156,000 stars.
