A pair of Voyager 2 images of Neptune's ring system. The first mention of rings around Neptune dates back to 1846 when William Lassell, the discoverer of Neptune's largest moon, Triton, thought he had seen a ring around the planet. [2] However, his claim was never confirmed and it is likely that it was an observational artifact.
The last time Neptune's rings were seen in detail was during a flyby in 1989 by NASA's Voyager 2 spacecraft as it journeyed beyond the solar system and into interstellar space. That historic flyby ...
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. [168] The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. [169]
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
NASA released new, highly detailed images of our solar system’s outermost planet on September 21, taken by the James Webb Space Telescope.The telescope’s infrared instruments captured the ...
The James Webb Space Telescope has captured its first image of Neptune, and it's the best view of the planet's rings in over 30 years.
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.
