A larger telescope reveals many smaller and fainter belts. These belts are views through the planet's atmosphere: as you see the different colors, you are looking down into the layers of Jupiter's clouds. Brown areas are the deepest. White areas are at medium altitude. And red areas are highest in Jupiter's atmosphere.

And the highest of the high is probably the Great Red Spot, a large storm similar to a typhoon on our planet—except that it's more than three times the size of Earth, and it's been raging since at least 1664, when it was first observed.
