Neptunes tiny moons may be the wreckage of shattered ancient worlds

JWST has uncovered surprising clues that Neptunes strange inner moons may be the wreckage of an ancient cosmic catastrophe. Researchers detected clay-like minerals on Larissa, Galatea, and Neptunes rings that form in the presence of liquid water-yet the moons themselves show no obvious water ice. The material likely came from deep inside much larger icy moons that were shattered when Triton was captured by Neptune, destroying much of the planets original satellite system.
