Polar Heat on Saturn

On the Earth and other bodies with poles, the polar regions are their coldest locations. While 91 Kelvin (-296 degrees Fahrenheit) may be colder than most people can imagine, Saturn’s south pole turns out to be the hottest spot on the planet. In a surprising discovery by the W.M. Keck I Observatory at Mauna Kea, Hawaii, temperature emissions were found to abruptly change at various latitudes on Saturn. Why the pole should be warmer than lower latitudes is not understood. Saturn has now become the only known body in our solar system with this characteristic.
