Artist Concept of Saturn's north pole

This artist's concept shows a glowing patch of ultraviolet light near Saturn's north pole that occurs at the “footprint” of the magnetic connection between Saturn and its moon Enceladus. The magnetic field lines and the footprint are not visible to the naked eye, but were detected by the ultraviolet imaging spectrograph and fields and particles instruments on NASA's Cassini spacecraft. The footprint, newly discovered by Cassini, marks the presence of an electrical circuit that connects Saturn with Enceladus and accelerates electrons and ions along the magnetic field lines. In this image, the footprint is in the white box marked on Saturn, with the magnetic field lines in white and purple.
