Saturn's hexagon was discovered during the Voyager mission in 1981, and was later revisited by Cassini-Huygens in 2006. During the Cassini mission, the hexagon changed from a mostly blue color to more of a golden color. Saturn's south pole does not have a hexagon, as verified by Hubble observations.
The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
Auroral lights at Saturn's north pole. Saturn has an intrinsic magnetic field that has a simple, symmetric shape—a magnetic dipole. Its strength at the equator—0.2 gauss (20 μT)—is approximately one twentieth of that of the field around Jupiter and slightly weaker than Earth's magnetic field. [32]
The interface between the cold dry air mass of the pole and the warm moist air mass farther south defines the location of the polar front. The polar front is centered roughly at 60° latitude. A polar vortex strengthens in the winter and weakens in the summer because of its dependence on the temperature difference between the equator and the poles.
North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole. [ 2 ] Relative to Earth's surface, the geographic poles move by a few metres over periods of a few years. [ 3 ]
What we didn't know was just how hot things were getting down at the South Pole. According to research published this week in the journalNature Climate Change, the region has been warming at more ...
A deep ocean exists beneath the icy, cratered surface of Saturn’s moon Mimas, according to a new analysis of data from NASA’s Cassini mission.
On Saturn, like on Jupiter, the north magnetic pole is located in the northern hemisphere, and the south magnetic pole lies in the southern hemisphere, so that magnetic field lines point away from the north pole and towards the south pole. This is reversed compared to the Earth, where the north magnetic pole lies in the southern hemisphere. [13]
