Neptune’s Elusive Rings Captured by James Webb Telescope

The James Webb Space Telescope (JWST) has revealed the sharpest view of Neptune’s rings since the Voyager 2 spacecraft visited the ice giant over 30 years ago.

Neptune, the eighth and most distant planet from the Sun, is something of an oddball, even by the weird and wonderful standards of our solar system. The ice giant owes its spectacular blue hue to the presence of methane in its crushing atmosphere, where it is thought to be so hot and dense that it quite literally rains diamonds.

Orbiting roughly 2.8 billion miles (4.5 billion km) from the Sun – which is roughly 30 times the distance between Earth and our star – Neptune is the only planet in our solar system that is impossible to see with the naked eye, even on the clearest of nights.
