Atmosphere of Uranus internal heat source was required to explain observed temperatures. No discrete features had been observed on Uranus prior to the "Voyager 2" visit in 1986. In January 1986, the "Voyager 2" spacecraft flew by Uranus at a minimal distance of 107,100 km providing the first close-up images and spectra of its atmosphere. They generally confirmed that the atmosphere was made of mainly hydrogen and helium with around 2% methane. The atmosphere appeared highly transparent and lacking thick stratospheric and tropospheric hazes. Only a limited number of discrete clouds were observed. In the 1990s and 2000s, observations by the Hubble Space
