Neptune’s inner moons and rings are exposed icy body interiors

The deep cobalt Neptune everyone recognises is largely an artefact of image processing, and when researchers reprocessed the Voyager 2 data with modern calibration they found Neptune and Uranus are almost the same pale greenish blue, with Neptune only marginally darker than its supposedly boring neighbour

The iconic sapphire Neptune, ingrained in textbooks and imagination for decades, turns out to be a trick of the darkroom.

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

Neptune's strange moon and ring system has puzzled astronomers for decades, but data from the James Webb Space Telescope (JWST) might help explain how it formed.

Neptune’s Inner Moons And Rings Might Be Left Over From A Cosmic Game Of Marbles Caused By The Capture Of Triton

Evidence suggests the giant planet captured its largest moon, then things went sideways.

Neptune’s inner moons and rings are exposed icy body interiors

Abstract Neptune’s single large moon, Triton, is accompanied by a set of dusty rings and small moons whose composition and origin are uncertain. Using the James Webb Space Telescope, we observed Neptune’s rings and three moons: Larissa, Galatea, and Proteus. These moons and rings have spectra that are distinct from other outer Solar System objects and show no evidence of water ice despite hosting deep 3-micrometer OH absorption bands. In additio…
