Saturn's north pole !

The hexagon is nearly 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 a standing atmospheric wave created by a powerful jet stream that wraps around the pole. Winds along its edges can exceed 300 km/h (about 220 mph).

At the very center of the hexagon lies a deep, dark polar vortex that extends hundreds of kilometers down into Saturn's atmosphere.

Concluding that the costs of keeping such a device in the bedroom far exceeded the benefits, a study released Monday by the University of Chicago’s sleep lab found a strong link between poor sleep and the presence of a gong. “Our research consistently revealed that one of the best predictors of a sleepless night was having a gong sound near one’s bed,” said lead author Dr. Sylvia Mott, who added that study participants reported falling asleep later and waking up earlier when exposed to the deafening clang of a gong being struck with a mallet.
