The rings of Jupiter are a system of faint planetary rings. The Jovian rings were the third ring system to be discovered in the Solar System, after those of Saturn and Uranus . The main ring was discovered in 1979 by the Voyager 1 space probe [ 1 ] and the system was more thoroughly investigated in the 1990s by the Galileo orbiter. [ 2 ]
Jupiter has a faint planetary ring system composed of three main segments: an inner torus of particles known as the halo, a relatively bright main ring, and an outer gossamer ring. [127] These rings appear to be made of dust, whereas Saturn's rings are made of ice.
Mark Robert Showalter (born December 5, 1957) is a senior research scientist at the SETI Institute. [1] He is the discoverer of six moons and three planetary rings. He is the Principal Investigator of NASA's Planetary Data System Rings Node, a co-investigator on the Cassini–Huygens mission to Saturn, and works closely with the New Horizons mission to Pluto.
As I wrote in that article, Jupiter’s main ring is primarily made of dust, and may be due to small particles impacting the two moons Metis and Adrastea; sunlight would push on the dust part
That mission, which is slated to end in September 2025, also extends to Jupiter's rings and many moons. Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon ...
Webb's new images of Jupiter showcase its auroras, rings, and extremely faint galaxies, which Hubble can't see. Side-by-side Jupiter images show James Webb's infrared prowess.
Jupiter's ring system was the third to be discovered, when it was first observed by the Voyager 1 probe in 1979, [11] and was observed more thoroughly by the Galileo orbiter in the 1990s. [12] Its four main parts are a faint thick torus known as the "halo"; a thin, relatively bright main ring; and two wide, faint "gossamer rings". [13]
Jupiter may be best known as the planetary titan of our solar system with a comparatively small red mark — that still dwarfs the entirety of Earth — and rows of striations going from pole to pole.
