These are the new results from a systematic study on Jupiter's wave environment taken from the Galileo Probe spacecraft.

Chorus waves are a special type of radio wave occurring at very low frequencies. Unlike the Earth, Ganymede and Europa orbit inside the giant magnetic field of Jupiter. It is believed Jupiter's giant magnetic field is one of the key factors powering the waves. Jupiter's magnetic field is the largest in the solar system, and some 20,000 times stronger than the Earth's.

"Chorus waves have been detected in space around the Earth but they are nowhere near as strong as the waves at Jupiter" says Professor Richard Horne of British Antarctic Survey who is a co-author on the study. "Even if small portion of these waves escapes the immediate vicinity of Ganymede, they will be capable of accelerating particles to very high energies and ultimately producing very fast electrons inside Jupiter's magnetic field".
