'Tiger stripes' found on Saturn moon
LONDON, England (Reuters) -- There is a hot spot on one of Saturn's moons which should not be there and has yet to be explained, scientists said on Tuesday.
It is located at the south pole of Enceladus, a moon with a diameter of just 310 miles.
The hot spot is unusual because it occurs at the pole, scientists said. Usually, the hottest part of any planet or moon is around the equator, as is the case with the Earth.
