Saturn’s stormy and geometrical north pole
Nasa’s Cassini spacecraft captured the top image of a storm over Saturn’s northern ‘polar hexagon.’ Why is it called a hexagon, you may ask? Because the second photo, also captured by Cassini shows that’s exactly what it looks like. It turns out that the hexagon isn’t a geographic feature of the planet, but is instead a weather phenomenon that has puzzled scientists since the 1980’s. The latest hypothesis is that fluid dynamics, combined just so with the speed of Saturn’s rotation and orbit, could be the cause of the hexagon.
