Of the planets in our solar system, those that have magnetic fields also
have a surrounding cloud of energetic electrons. The cloud surrounding
the Earth is also known as the van Allen belt. These electrons are
magnetically trapped, and emit radio waves. Jupiter, the largest planet
in the Solar System, has by far the most complex and energetic electron
population surrounding it. This image shows the planet Jupiter itself
(in red) surrounded by the disk of electrons (in blue). Because of an
interaction with Amalthea, a minor moon of Jupiter, the disk thickens
near the planet.
