One of the best-known features of Jupiter is the great red spot. It’s been there for hundreds of years, and it’s a big storm, a vast hurricane on Jupiter. And when the Voyager spacecraft got a look at that, it noticed you get complicated, turbulent vortices spinning off. What we see on Jupiter is turbulence. Big vortices, smaller vortices, tiny vortices, and if we could look closely — smaller and smaller and smaller ones.
