PLANET URANUS
Image 1:
The picture on the left has been processed to show Uranus as human eyes would see it from the vantage point of the spacecraft. The picture is a composite of images taken through blue, green, and orange filters. The blue-green color results from the absorption of red light by methane gas in Uranus' deep, cold, and remarkably clear atmosphere. The darker shadings at the upper right of the disk correspond to the day-night boundary on the planet. (1986)

Image 2:
This color photo of Umbriel, the darkest of Uranus' five large moons, was taken by Voyager 2 on Jan. 23, 1986. At the
time, the spacecraft was 1.04 million kilometers (650,000 miles) from Umbriel and heading for a Jan. 24 closest approach. Umbriel is characterized by the darkest surface and smallest brightness variations of any of the large satellites of Uranus. As seen here, the surface is also generally gray and colorless.
