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.
In April of last year, Cassini spent 44 hours staring at Saturn's atmosphere and capturing in-depth images. The mission to Saturn is a joint venture between NASA, the European Space Agency and the ...
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 water ice is delivered by powerful convections originating from about 200 km deep in Saturn's atmosphere. [14] The 2010 GWS also had an increased level of lightning. It had 10 Saturn Electrostatic Discharges (SED) per second, while synoptic-scale storms on Saturn had a few SEDs per seconds. [5]

Saturn's atmosphere has several unusual features. Its winds are among the Solar System's fastest, with Voyager data indicating peak easterly winds of 500 m/s. It is also the only planet with a warm polar vortex, and is the only planet other than Earth where eyewall clouds have been observed in hurricane -like structures.
An event timer on the probe would initiate activities, while the carrier–relay spacecraft would power up its radio receiver and turn to point its probe-relay antenna to the entry site. The probe would enter Saturn's atmosphere at a velocity of approximately 27 km/s, which is less than the Galileo Probe's velocity of 47.4 km/s. After the entry ...
Voyager 2 probed Saturn's upper atmosphere with its radar, to measure temperature and density profiles. Voyager 2 found that at the highest levels (7 kilopascals pressure) Saturn's temperature was 70 K (−203 °C) (i.e. 70 degrees above absolute zero), while at the deepest levels measured (120 kilopascals) the temperature increased to 143 K ...
