JWST Observations Suggest Ancient Catastrophic Event Shaped Neptune's Moons and Rings

Caltech researchers, using James Webb Space Telescope data, found Neptune's rings and three moons (Larissa, Galatea, Proteus) have a unique composition. This suggests an original moon system was destroyed when Triton, Neptune's largest moon, was captured. The debris from this ancient collision likely formed the current moons and rings, offering insights into planetary evolution and the dynamic history of our solar system.
