It towered hundreds of kilometres over the clouds, and showed quite different behaviour from the southern vortex. It's cooler, not as mature, and, of course, the south pole has no hexagon. But since wind conditions change dramatically with altitude, the fact that the hexagon shape persists so much higher than the cloud tops is a baffling conundrum.

Researchers have generally regarded the 20,000-mile-wide (32,000 kilometers) hexagon — a jet stream composed of air moving at about 200 mph (320 km/h) — as a lower-atmosphere phenomenon, restricted to the clouds of Saturn's troposphere.
But the bizarre structure actually extends about 180 miles (300 km) above those cloud tops, up into the stratosphere, at least during the northern spring and summer, a new study suggests. [Stunning Photos: Saturn's Weird Hexagon Vortex Storms]
