When was the first image of Uranus taken?
Taking its first peek at Uranus, NASA Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer (NICMOS) has detected six distinct clouds in images taken July 28, 1997. Hubble also captured eight moons in this image.
Which is the darkest of the Uranian moons?
Umbriel is the darkest of the Uranian moons, and has an icy crust pockmarked by craters. The surface is uniform in reflectivity, with the exception of a bright ring (top), which may be an impact crater. The outermost of the five major satellites, Oberon, appears much like the satellites.
