Io is the size of our Moon, and Jupiter is very big. The left is natural color, composited to yield the color that Jupiter would have if seen by the naked eye. The combination yields an image whose colors denote the height of the clouds.

From images like these, the stratigraphy of Jupiter's dynamic atmosphere will be determined.
