Knowra Atmosphere of Uranus Atmosphere of Uranus The gaseous envelope surrounding Uranus, composed mainly of hydrogen and helium, with methane and traces of other gases. Its cold, cloud-layered atmosphere has unusually subdued visible features and powerful winds.
Uranus cloud layers : The vertically arranged cloud and haze regions in Uranus’s atmosphere, including layers involving methane, hydrogen sulfide, and deeper clouds. Different condensates form at different pressures, revealing the atmosphere’s vertical structure.
Uranus : The seventh planet from the Sun, an ice giant with a faint ring system and 98-degree axial tilt. The atmosphere is the observable outer envelope of this ice giant.
Voyager 2 : The NASA spacecraft that made the only close flyby of Uranus in January 1986. Its images and measurements established much of the direct evidence about Uranus’s atmosphere.
Atmosphere of Neptune : The gaseous envelope of Neptune, composed chiefly of hydrogen and helium with methane and other trace gases. Neptune’s more conspicuous storms and greater internal heat contrast with Uranus’s muted weather.
Methane on Uranus : Methane gas in Uranus’s atmosphere, which absorbs red light and gives the planet its blue-green appearance. Methane’s absorption also helps identify atmospheric layers and cloud heights.
Uranus interior : The layered structure beneath Uranus’s atmosphere, including a hydrogen-helium envelope and a dense, hot interior. Heat from below may contribute energy to atmospheric circulation and weather.
Uranus atmospheric entry probe : A proposed spacecraft probe designed to descend through Uranus’s atmosphere and measure its composition and structure. A probe could directly sample gases that remote observations infer indirectly.
Atmosphere of Saturn : The gaseous envelope of Saturn, dominated by hydrogen and helium and marked by bands, storms, and seasonal changes. Saturn’s warmer, more visibly active atmosphere provides a contrast in giant-planet circulation.
Uranus weather : The changing winds, clouds, storms, and seasonal atmospheric patterns observed on Uranus. Cloud tracking shows rapid winds and weather that varies despite weak sunlight.
Uranus rotation : Uranus’s rotation, which has a period of about 17 hours and an unusual orientation relative to its orbit. Rotation organizes atmospheric jets, while the tilted axis complicates their seasonal forcing.
