atmosphere and weather
Uranus appears featureless, but this is in part due to haze in the upper atmosphere obscuring our view. The haze is produced by ultraviolet sunlight interacting with atmospheric methane. Uranus has no complex weather system, but ammonia and water clouds are carried around the planet by its winds and rotation. The cloud-top temperature is around —353°F ( —214°C).
This infrared image of Uranus reveals the cloud structure. The highest clouds appear white; the mid-level ones bright blue; and the lowest darker blue. Image processing has turned the rings a colorful red.
Hydrogen is the main element in the atmosphere. The methane gives Uranus its blue color; it absorbs incoming red wavelengths of light and reflects the blue.
