Astronomers have discovered two rare Jupiter-sized "super-puff" exoplanets more than 1,100 light-years from Earth.

Despite their enormous size, these worlds have an incredibly low density, consisting mostly of hydrogen and helium, making them among the lightest planets ever found.

The discovery offers new clues about planet formation, while future observations with the James Webb Space Telescope could reveal the secrets hidden within their unusual atmospheres.
