Editing Saturn (section)

==== Storms and spots ====
Saturn's atmosphere can make oval-shaped clouds. These clouds are like the clearer spots seen on Jupiter. These oval spots are rotating storms, similar to [[cyclone]]s seen on Earth. In 1990, the [[Hubble Space Telescope]] found a very large white cloud near Saturn's equator. Storms like this one in 1990 were known as [[Great White Spot]]s. These unique storms only exist for a short time and only occur in about every 30 Earth years, in [[summer]] [[solstice|solstices]] in the [[Northern Hemisphere]].<ref>{{cite journal |url=http://www.sciencedirect.com/science/article/pii/S0019103505000308 |title=Saturn's cloud structure and temporal evolution from ten years of Hubble Space Telescope images (1994–2003) |last=S.

The [[Voyager 1]] spacecraft found a [[hexagon]]al cloud [[pattern]] near Saturn's north pole at about [[longitude|78°N]]. The [[Cassini−Huygens]] probe later [[wikt:confirm|confirmed]] it in 2006. Unlike the north pole, the south pole does not show any hexagonal clouds. The Cassini-Huygens probe also found a [[hurricane]]-like storm on the south pole that showed an [[eye (cyclone)|eyewall]]. Until this finding, eyewalls had only been seen on Earth.<ref>{{cite web |url=https://www.newscientist.com/article/dn10499 |title=Spectacular storm rages on Saturn's south pole  |first= Maggie|last=McKee |work=New Scientist Magazine |date=November 6, 2006 |access-date=April 21, 2011}}</ref>
