Rings of Neptune imaged by the James Webb Space Telescope's NIRCam instrument. The rings of Neptune consist primarily of five principal rings.They were first discovered (as "arcs") by simultaneous observations of a stellar occultation on 22 July 1984 by André Brahic's and William B. Hubbard's teams at La Silla Observatory (ESO) and at Cerro Tololo Interamerican Observatory in Chile. [1]
The radio instruments on board found that Neptune's day lasts 16 hours and 6.7 minutes. Neptune's rings had been observed from Earth many years prior to Voyager 2 's visit, but the close inspection revealed that the ring systems were full circle and intact, and a total of four rings were counted.

As of 2024, no large planet has been found beyond Neptune that would explain any alleged discrepancy, despite the discovery of trans-Neptunian objects (most notably, Pluto). While the astronomical community widely agrees that "Planet X", as originally envisioned, does not exist, the concept of an as-yet-unobserved planet has been revived by a ...
Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar ...
The next moon, Galatea, orbits just inside the most prominent of Neptune's rings, the Adams ring. [21] This ring is very narrow, with a width not exceeding 50 km, [22] and has five embedded bright arcs. [21] The gravity of Galatea helps confine the ring particles within a limited region in the radial direction, maintaining the narrow ring.
The ice giants Uranus and Neptune live up to their name. Although humans have only ever sent one spacecraft (Voyager 2) toward these far-flung worlds, scientists have a pretty good idea that these ...
Neptune's rings and moons viewed in infrared by the James Webb Space Telescope. Neptune has a planetary ring system, though one much less substantial than that of Saturn and Uranus. [167] The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. [168]
Police confirmed to WSVN that the body was found in a storage closet. The elderly man’s family said on Monday, Sept. 2, they were informed about his death. His niece Kimberly Etienne alleged to ...
