Nothing like the hexagon has ever been seen on any other world.
The structure, which contains a churning storm at its center, is about 20,000 miles wide and reaches roughly 60 miles down into Saturn’s atmosphere.
The bizarre hexagonal cloud pattern was first discovered in 1988 by scientists reviewing data from NASA’s Voyager flybys of Saturn in 1980 and 1981, but its existence was not confirmed until NASA’s Cassini spacecraft observed the ringed planet up-close years later. The entire structure is large enough for four Earths to fit inside.

- Saturn is the least dense planet in our Solar System
