Neptune's moon system is bizarre. JWST data helps explain why

Neptune's moon system is unusually unbalanced compared to other gas giants like Jupiter and Saturn. Its largest moon, Triton, which makes up over 99% of the mass of all Neptune's satellites, orbits in a retrograde direction—opposite to Neptune's rotation—suggesting it may have been captured from the Kuiper Belt rather than forming alongside Neptune. This capture event could have disrupted any existing moon system Neptune once had. Using the James Webb Space Telescope (JWST), scientists analyzed light from Neptune's smaller inner moons and rings, discovering traces of phyllosilicate clay minerals. These minerals require liquid water to form, but the small moons are too cold for such processes. The findings suggest the clay originated from a larger, warmer body that may have existed before being destroyed during Triton's capture.
