JWST Observations Suggest Catastrophic Event Shaped Neptune's Moon System

Caltech researchers, utilizing data from NASA's James Webb Space Telescope (JWST), have studied Neptune's rings and three of its moons—Larissa, Galatea, and Proteus. Their findings indicate a unique composition among outer solar system bodies, suggesting that an original moon system was destroyed when Neptune gravitationally captured its largest moon, Triton. The remnants from this ancient collision are believed to have coalesced to form the currently observed moons and rings.
