Order from Chaos

On the Cover: The Great Red Spot dominates Jupiter's southern hemisphere, where it has been watched by Earth-based observers for 300 years. Turbulent eddies, such as the Great Red Spot and the white ovals seen here, are characteristic of giant planet atmospheres. They lie within and between the zonal winds, blowing east and west, that give Jupiter and Saturn their banded appearances.
