Zonal wind speeds on Uranus. Shaded areas show the southern collar and its future northern counterpart. The red curve is a symmetrical fit to the data. The emergence of a dark spot on the hemisphere of Uranus that was in darkness for many years indicates that near equinox Uranus entered a period of elevated weather activity. [5]
Temperature profile of the Uranian troposphere and lower stratosphere. Cloud and haze layers are also indicated. The Uranian atmosphere can be divided into three main layers: the troposphere, between altitudes of −300 [a] and 50 km and pressures from 100 to 0.1 bar; the stratosphere, spanning altitudes between 50 and 4000 km and pressures between 0.1 and 10 −10 bar; and the thermosphere ...
Solar wind hit Uranus and dramatically compressed its magnetosphere, likely pushing plasma out of it. But the solar wind also made Uranus’ magnetosphere more dynamic by feeding it with electrons ...
An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery ...
The pronunciation of the name Uranus preferred among astronomers is / ˈ jʊər ə n ə s / YOOR-ə-nəs, [1] with the long "u" of English and stress on the first syllable as in Latin Uranus, in contrast to / j ʊ ˈ r eɪ n ə s / yoo-RAY-nəs, with stress on the second syllable and a long a, though both are considered acceptable.

Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings. Images of which were captured in rich detail last year by the James Webb Space Telescope .
The storm had some of the highest recorded wind speeds in the Solar System at approximately 2,400 km/h (1,500 mph) and rotated around the planet once every 18.3 hours. [36] When the Hubble Space Telescope turned its gaze to Neptune in 1994, the spot had vanished; but the storm causing the spot might have continued lower in the atmosphere.
In 1986, Nasa’s Voyager 2 flew by the seventh planet in the Solar System, providing scientists with their first and only glimpse of Uranus, and shaping their understanding of it since.
