This view from NASA's Cassini spacecraft features a blue planet, Uranus, imaged by Cassini for the first time. Uranus is a pale blue in this natural color image because its visible atmosphere contains methane gas and few aerosols or clouds.
This picture is part of NASA's Voyager 2 imaging sequence of Ariel, a moon of Uranus taken on January 24, 1986. The complexity of Ariel's surface indicates that a variety of geologic processes have occurred.
One wide-angle and eight narrow-angle camera images of Miranda, taken by NASA's Voyager 2, were combined in this view. The controlled mosaic was transformed to an orthographic view centered on the south pole.
This 'family portrait' of Uranus' five largest moons was compiled from images sent back Jan. 20, 1986, by NASA's Voyager 2 spacecraft. Even in these distant views, the satellites exhibit distinct differences in appearance.
Several craters are seen on the surface of 1985U1, one of several small moons of Uranus discovered by NASA's Voyager 2. The spacecraft acquired this single image, the only
close-up it obtained of any of the new moons, on Jan. 24, 1986.
Voyager 2 obtained this full-disk view of Uranus' moon Titania in the early morning hours of Jan. 24, 1986, from a distance of about 500,000 kilometers (300,000 miles). Many circular depressions, probably impact craters, are visible in this clear-filter.
Voyager 2 has discovered two 'shepherd' satellites associated with the rings of Uranus. The two moons, designated 1986U7 and 1986U8, are seen here on either side of the bright epsilon ring; all nine of the known Uranian rings are visible.
These two pictures of Uranus were compiled from images recorded by NASA's Voyager 2 on Jan. 1O, 1986. This view is toward the planet's pole of rotation, which lies just left of center. The image on the right is a false-color image.
Distinct bright patches are visible on Ariel, the brightest of Uranus' five largest satellites. NASA's Voyager 2 obtained this image Jan. 22, 1986, from a distance of 2.52 million kilometers (1.56 million miles).
