What is the great red spot?
It's a swirling mass of gas and colored clouds that is bigger than the earth. It's been around since the telescope was invented; maybe it's much older than that, even.
People sometimes call it a hurricane but it's probably different from a hurricane in the way it works.
There's no ocean underneath, and it's much bigger than a hurricane and doesn't have any intense eye at the center.
The red spot is rolling like a ball bearing between two conveyer belts.
Just to the north of the red spot, there's a westward moving jet stream, and just south of the red spot there's an eastward moving jet stream.
Somehow the jet streams steady the red spot and keep it trapped at one latitude.
There's no solid surface with which to measure your wind speed. It speeds up and slows down slightly. It's not anchored to anything - it's on its own schedule.
