Astronomers got lucky. "A huge planet with a long name – IRAS 04125+2902 b – is really just a baby: only 3 million years old," NASA recently explained. "And because such infant worlds are usually ...

A four-planet system observed several years ago by the Kepler spacecraft is actually a rarity: Its planets, all miniature Neptunes nestled close to the star, are orbiting in a unique resonance that ...
