Research Suggests Neptune's Inner Moons and Rings Formed from Colliding Ice Worlds

New research led by Caltech proposes that Neptune's inner moons, including Proteus, Larissa, and Galatea, along with its ring system, may have originated from the fragmented remains of ancient icy worlds. This catastrophic event is potentially linked to the gravitational capture of Triton, suggesting a violent past for the outer solar system. The study offers insights into planetary formation and evolution.
