Webb telescope finds signs of ancient disaster for Neptune's moons

New observations from NASA's James Webb Space Telescope reveal that Neptune's inner moons and rings contain clay minerals formed in liquid water, suggesting a catastrophic event billions of years ago. The likely culprit is Triton, a captured Kuiper Belt object whose gravity disrupted Neptune's original moons, causing collisions that formed the current system. This study offers a rare glimpse into the interiors of large icy moons, which are usually hidden.
