Saturn's north pole !
The hexagon is nearlyΒ 30,000 km (20,000 miles) wide. This is large enough that two Earths could fit inside the storm with room to spare.
It is aΒ standing atmospheric waveΒ created by a powerful jet stream that wraps around the pole. Winds along its edges can exceedΒ 300 km/h (about 220 mph).
At the very center of the hexagon lies a deep, darkΒ polar vortexΒ that extends hundreds of kilometers down into Saturn's atmosphere.
