One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere. [22] Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery.
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 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.
Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn. With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded in shape due to its own gravity.
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 ...

Measure the temperature of Saturn's atmosphere and that of Titan, the largest satellite of Saturn. Determine the structure of the upper atmosphere of Saturn where molecules are expected to be electrically charged and form an ionosphere. Map the thermal structure of Saturn's atmosphere by infrared observations coupled with radio occultation data.
Phoebe (/ ˈ f iː b i / FEE-bee) is the most massive irregular satellite of Saturn with a mean diameter of 213 km (132 mi). It was discovered by William Henry Pickering on 18 March 1899 [9] from photographic plates that had been taken by DeLisle Stewart starting on 16 August 1898 at the Boyden Station of the Carmen Alto Observatory near Arequipa, Peru.
