Jupiter's auroral ring and polar haze

This photo shows the Jovian aurorae, in particular the northern ring (here shown in yellow/orange) as well as the "polar haze" (blue). The visibility of the various features has been enhanced by the use of false-colours. The moon Io is visible to the left.

Technical information: this image is a colour-coded combination of these four exposures. North is up and East is left.
