Saturn's atmosphere exhibits a banded pattern similar to Jupiter's, but Saturn's bands are much fainter and are much wider near the equator. The nomenclature used to describe these bands is the same as on Jupiter. Saturn's finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s.
The atmosphere of Uranus is composed primarily of gas and various ices. It is about 83% hydrogen, 15% helium, 2% methane and traces of acetylene. Like Jupiter and Saturn, Uranus has a banded cloud layer, although this is not readily visible without enhancement of visual images of the planet.
The sun passes south to north through the ring plane when Saturn's heliocentric longitude is 173.6 degrees (e.g. 11 August 2009), about the time Saturn crosses from Leo to Virgo. 15.7 years later Saturn's longitude reaches 353.6 degrees and the sun passes to the south side of the ring plane.
The sky in the upper reaches of Saturn's atmosphere is blue (from imagery of the Cassini mission at the time of its September 2017 demise), but the predominant color of its cloud decks suggests that it may be yellowish further down. Observations from spacecraft show that seasonal smog develops in Saturn's southern hemisphere at its perihelion ...
The Hubble Space Telescope captured a newly revealed image of the mysterious, ghostly shadows on Saturn’s rings — the latest sighting of the so-called “spokes” that continue to baffle ...
Saturn's Great White Spot, imaged by NASA's Cassini Spacecraft in 2011 False color image of the Dragon Storm, imaged by Cassini. Every Saturn year, about 28 Earth years, Saturn has massive planet-circling storms, called Great White Spots. The Great White Spots are short-lived but can impact the atmosphere and temperature of the planet for up to ...

The Great White Spot, also known as Great White Oval (named by analogy to Jupiter's Great Red Spot) is a series of periodic storms on the planet Saturn that are large enough to be visible from Earth by telescope by their characteristic white appearance. The spots can be several thousands of kilometers wide.
