The years were worth the wait. JWST gives us an amazing view of Neptune's rings
The bright blue-looking spot with diffraction spikes in the upper left of the above snap is Neptune's biggest moon, Triton, which has an odd retrograde orbit and is one of the few geologically active natural satellites in the Solar System.
There are six other moons that appear as small blurry blobs; three of them, Galatea, Naiad, Thalassa, are on the left side of Neptune nestled in the dust rings, while Despina is on the right. Larissa is directly below Despina outside the rings, and Proteus is further away to the right. Neptune is rich in heavier elements, and looks blue due to small amounts of methane in its atmosphere. Comparisons of images from the Hubble Space Telescope and the James Webb Space Telescope show what the planet looks like at different wavelengths. Observations of Neptune in visible light by Hubble show the planet's color but misses other details, whereas viewing it infrared reveals its dust rings.
