Although Jupiter and Saturn are similar gas giants, their polar weather patterns are strikingly different. Saturn hosts a single, massive hexagonal storm at its north pole, while Jupiter features a central cyclone surrounded by smaller vortices. New simulations suggest the contrast may arise from differences deep inside the planets.
