Saturn’s hexagon is a persisting six sided cloud pattern around the north pole of the planet. It is created by a band of upper-atmospheric winds, and the sides of it are about 13,800 km (8,600 mi) long, which is longer than the Earth’s diameter. There’s a hurricane swirling within the hexagon.

Why do magnets fall more slowly through a copper tube?
This never ceases to blow my mind.
Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore—
While I nodded, nearly napping, suddenly there came a tapping
As of some one gently rapping, rapping at my chamber door—
“‘Tis some visitor,” I muttered, “tapping at my chamber door—
Only this and nothing more.”
Ah, distinctly I remember it was in the bleak December;
And each separate dying ember wrought its ghost upon the floor.
Eagerly I wished the morrow;—vainly I had sought to borrow
From my books surcease of sorrow—sorrow for the lost Lenore—
For the rare and radiant maiden whom the angels name Lenore—
Nameless here for evermore.
The Raven, Edgar Allan Poe
