This was the closest view of the old and massive storm that gives Jupiter its trademark red spot. The Great Red Spot has been raging on Jupiter for at least 400 years when humans first observed the giant planet. Three Earths can fit into the storm, which is similar to a hurricane. The Voyagers discovered many hurricane-like storm systems rampaging in Jupiter's atmosphere.
Voyager photographed a ring around Jupiter.
The lines that cross Jupiter's moon Europa were first seen by earlier space probes, but Voyager 2 showed that Europa's features were so flat, they "might have been painted on with a felt marker," according to a scientist. It is believed that the planet's surface may be covered by a water ice crust of up to three miles--hiding oceans as deep as 30 miles.
