Uranus and Rings - Voyager
Voyager 2 natural color composite image of Uranus and its ring system, taken late on January 23, 1986. This view combines a single-frame color image of Uranus and a 6 frame mosaic of its ring system taken a few hours later. The rings here are significantly fainter relative to Uranus than pictured here; the charcoal black rings would be near the limits of naked eye visibility to a human observer.
The color image of Uranus shows significantly more cloud detail than previous processings of Voyager 2 data. This is because the Uranian clouds are dominated by a high-altitude hydrocarbon haze that hides cloud belts (similar to those found at Jupiter, Saturn, and Neptune) at most visible wavelengths. The underlying clouds are most visible at red and near-infrared wavelengths, which Voyager's camera was blind to. These features were faintly captured in images taken through Voyager's orange filter, and have been enhanced to make these details visible.
