Jupiter's Auroras Helped by Io (http://www.universetoday.com/am/publish/jupiter_voltage_aurora.html?232005)


Jupiter's massive magnetic field is so powerful, it can generate auroras one thousand times more powerful than we'll see here on Earth. One of the best ways to study Jupiter's aurora is in the X-ray spectrum, watching how particles and ions crash into Jupiter's atmosphere. Observations from NASA's Chandra X-Ray Observatory suggest that these particles are partly coming from the Sun, but also from Io, Jupiter's volcanically active moon, which is known to be blasting out steady streams of particles.
