Telescope Shows Uranus Has Single-Layer Rings
Uranus’ rings are unique in that they are only one layer thick, according to new observations made with the Keck II telescope in Hawaii. Jupiter’s rings, in contrast, are much thicker.
The team, from the Space Science Institute in Boulder, Colo., also spotted an inner ring, the eleventh, that had been seen only once in an image taken by the Voyager 2 spacecraft in 1986.
The rings are composed of large boulders, but they are only one rock thick.
