Uranus Voyager 2
|
|
This picture of Uranus was compiled from images recorded by Voyager 2 on January 10, 1986, when the NASA spacecraft was 18 million kilometers (11 million miles) from the planet. The images were obtained by Voyager's narrow-angle camera; the view is toward the planet's pole of rotation, which lies just left of center. The picture has been processed to show Uranus as human eyes would see it from the vantage point of the spacecraft. The dark shading of the upper right edge of the disk is the terminator, or day-night boundary. The blue-green appearance of Uranus results from methane in the atmosphere; this gas absorbs red wavelengths from the incoming sunlight, leaving the predominant bluish color seen here. The Voyager project is managed for NASA by the Jet Propulsion Laboratory.
