This second edition should be considered the definitive detailed description of what we know about Uranus. Uranus: The Planet, Rings and Satellites is couched in terms an interested non–specialist can readily understand, but contains the level of organization and detail which also makes it a valuable resource for planetary scientists. Significant new data about Uranus and its system have been collected by HST since the Voyager 2 flyby in 1986. Although planetary scientists continue to mull over the Voyager data, considerable changes in our understanding of Uranus have occurred since the first edition. This second edition incorporates those changes (such as how the rings of Uranus were found) and also include pictures from the Hubble Space Telescope.
