Saturn - Voyager 2

False color close-up image of Saturn's atmosphere from 7.1 million km

Voyager 2 close-up of Saturn's cloud tops in false color.
The image was made by combining green and violet filter
images taken on 19 August 1981, one week before closest
approach. The smallest visible features in this image
are about 130 km across. The blue oval at the center
of the image would be brown in true color. The
features directly south of the oval are moving about
70 km/hr west relative to the oval, while the wave
like structures to the north are moving east at
540 km/hr. The frame is about 52,000 km from top
to bottom. North is at 11:00.
