The rings of Uranus (and some of its moons) are shown in the adjacent Hubble Space Telescope image. The rings were discovered from the Earth in 1977 when Uranus occulted (passed in front of) a star and it was noticed that there were dips in the brightness of the star before and after it passed behind the body of Uranus.

This animation illustrates the view from Voyager 2 during the occultation of the star sigma Sgr by Uranus' ring system. The Voyager photopolarimeter (PPS) and ultraviolet spectrometer (UVS) observed the occultation, providing precise information about the locations and opacities of these narrow rings.

The 9 main rings of Uranus are visible here as horizontal lines. The somewhat fainter, pastel lines seen between the rings are artifacts of computer enhancement. Six narrow-angle images were used to extract color information from the extremely dark and faint rings.

Uranus has 27 fascinating moons and a complicated ring system. The ring is a completely different form of ring than the one around Saturn or Jupiter. At Uranus there is a very obvious partial ring, or "ring arc".

All nine previously known rings of Uranus were photographed and measured, as were other new rings and ringlets in the Uranian system. These observations showed that Uranus's rings are distinctly different from those at Jupiter and Saturn.
