NASA's Kepler finds more than 100 new planets
Astronomers have confirmed the discovery of 104 new planets outside the solar system, which were found using NASA's Kepler spacecraft. The planets, all 20%-50% larger than Earth, are orbiting the M dwarf star K2-72, located 181 light-years away. The discoveries were made by measuring a subtle dip in the star's brightness caused by a planet's passage in front of it.
