It turns out, exoplanets can be as sweet as a trip to the state fair: Two worlds discovered by NASA's Kepler Space Telescope have about the same density as a package of cotton candy. The two planets, ...

"These ultra-low density planets are rare and they defy conventional understanding of how gas giants form, and if explaining how one formed wasn't difficult enough, this system has three!" When you ...
