Jupiter has a permanent ring of auroral light surrounding each of its poles (see photo). Most of the charged particles responsible for the light have long been thought to originate from tiny, hyperactive Io, which burps out about a tonne of sulphur per second in its persistent, violent volcanic activity. However, the sun was thought to cause any variations in the rings via changes in the pressure of the solar wind.
