Webb Telescope Data Suggests Neptune's Inner Moons are Remnants of Past Collision

Observations from the James Webb Space Telescope indicate Neptune's small inner moons are debris from an ancient cosmic event. Researchers found clay-like minerals on Larissa, Galatea, and Neptune's rings, suggesting liquid water was present despite no visible ice. This supports the hypothesis that an original moon system was destroyed during the capture of Triton, Neptune's largest moon.
