Bands and vortex in the atmosphere of Uranus

Bands and vortex in the atmosphere of Uranus

Fig. 11.2 . Although Uranus is similar in size and atmosphere composition to Neptune, it does not appear to have as active an atmosphere. A bright band at about 40 degrees southern latitude (left) nevertheless stretches out in the direction of rotation, and a dark, elongated whirling vortex, up to 3,000 kilometers across, formed at about 27 degrees latitude in the northern hemisphere (right), which is just beginning to be exposed to sunlight after many years of being in shadow. This three-wavelength composite image was taken from the Hubble Space Telescope on 23 August 2006. (Courtesy of NASA/ESA/L. Sromovsky and P. Fry, U. Wisconsin, H. Hammel, STScI, and K.
