The weirdest planet in the Solar System keeps getting weirder. The latest finding from the Cassini probe orbiting Saturn is that the ringed planet has a mysterious bright aurora which physicists on Earth are still trying to puzzle out. The aurora covers the whole polar area of the planet and is very bright and energetic -- even though the Sun is going through an unusually quiet period right now.
Is there any connection between the anomalous aurora and Saturn's equally mysterious polar hexagon? Nobody knows. And those are two words dear to every scientist's heart.
