The Great Red Spot storm, which has lasted 150 years that we know of, is continuing to shrink — but astronomers don’t know why. Hubble will continue observations of Jupiter to gain insight into the storm.
Other storms much smaller in size dot the surface, represented by brown or white ovals. They can last hours or centuries.
Below the Great Red Spot is a shape similar to a worm, but it’s really a cyclone spinning in the opposite direction of the storm above it.
Parallel cloud bands also stand out. They are created by ammonia ice clouds that vary in height and thickness, with air flowing in different directions, depending on their latitudes. The lighter bands rise the highest, while thicker clouds represent the darker ribbons in the band.
The rapid winds separating these clouds can reach 403 miles per hour.
