Saturn's Hexagon in Motion It was discovered in the 1980s and has since captured the attention of both scientists and the general public. 🪐 Saturn wears a hexagon on its crown. At the north pole, the clouds do not swirl in a circle. They lock into six straight sides and spin. Each wall of that storm is longer than Earth is wide. The whole figure could swallow our planet twice over and still have room. Voyager first caught the edge of it in the early 1980s — a geometry so clean it looked like a drafting error. Cassini later stared it down for years: a jet stream roaring around the pole at hundreds of kilometers an hour, holding its shape through winter dark and summer gold. Planets are supposed to be messy. Saturn’s north pole prefers a ruler. After four decades, the hexagon is still there, still turning, still refusing to become a circle.
