This trio of <I>Voyager 2</I> images of Uranus shows the varying appearance of the planet when photographed through the different color filters of the spacecraft?s wide-angle camera. The images were taken January 23, 1986, through?from left to right? violet, orange, and methane filters. The brighter areas in the methane image are generally high clouds where the light-scattering particles lie above the methane gas. The methane image?s bright clouds are probably convective regions where particles have been carried upward, above the absorbing methane gas. The dark band at the same latitude is a deeper cloud that lies within the absorbing methane. The region near the very edge of the planet appears bright in the methane image because the oblique viewing geometry concentrates light scattered from haze at high altitudes, where methane gas is absent.
