Aurorae on Jupiter. Coloured ultraviolet Hubble Space Telescope (HST) image of aurorae (light blue) at the north pole of Jupiter. These are caused when charged particles from the Sun (the solar wind) interact with Jupiter's magnetic field. The particles are channelled to the poles,where they collide with gases in Jupiter's upper atmosphere,causing them to emit light. Footprints of three of Jupiter's moons are also seen as dots of light. These are caused by electric currents produced by the satellites. The prints of Io (far left),Ganymede (lower right) and Europa (below and right of Ganymede's) are seen | |
