An Auroral Ring on Jupiter.

Do other planets have aurora? Terrestrial and spacecraft observations have found evidence for aurora on Venus , Mars , Jupiter , Saturn , Uranus , and Neptune . In the above false-color photograph , a good portion of an auroral ring was captured recently in optical light by the Galileo spacecraft in orbit around Jupiter . Auroral rings encircle a planet's magnetic pole, and result from charged particles spiraling down magnetic field lines. Although the surroundings near Jupiter are much different than Earth , the auroral rings appear similar.
