Details in the radiation belts close to Jupiter are mapped in these images using measurements made by NASA’s Cassini spacecraft as it flew past the giant planet in 2000. The colorful glow around the planet is from radio emission produced by high-energy electrons moving at nearly the speed of light within the radiation belts. The three views show the belts at different points in Jupiter’s 10-hour rotation. A picture of Jupiter is superimposed to show the size of the belts relative to the planet.
