Images from the Galileo and New Horizons space probes show the presence of two sets of spiraling vertical corrugations in the main ring. These waves became more tightly wound over time at the rate expected for differential nodal regression in Jupiter's gravity field.
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]
1979 – Voyager 1 flies by Jupiter and discovers its faint ring system, as well as volcanoes on Io, the innermost of its Galilean moons. [201] 1979 – Voyager 2 flies by Jupiter and discovers evidence of an ocean under the surface of its moon Europa. [202] 1980 – Voyager 1 flies by Saturn and takes the first images of Titan. [203]
NASA's James Webb Space Telescope captured new images of auroras, giant storms and swirling clouds on Jupiter, the largest planet in our solar system.
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.
In both the ancient Greek and Roman civilizations, Jupiter was named after the chief god of the divine pantheon: Zeus to the Greeks and Jupiter to the Romans. [19] The International Astronomical Union formally adopted the name Jupiter for the planet in 1976 and has since named its newly discovered satellites for the god's lovers, favourites, and descendants.

This photo, and many other images that have been released from Juno's extended mission, employs color enhancement to help visualize the depth between the layers of clouds in Jupiter's deep atmosphere.
