Most observations of Jupiter's weather are done by amateurs, who can talk about bands changing color, the size of the Great Red Spot shrinking, and other phenomena on the solar system's larger planet. Juno will be able to probe beneath the surface, however, to see what is happening underneath. It is poorly understood how deep weather features go on the giant planet, so Juno will give astronomers a better glimpse.

By observing in three different wavelengths, astronomers were able to spot the south equatorial band of Jupiter reappearing by looking beneath cloudtops. Credit: NASA/JPL/UH/NIR
