Saturn has northern lights, too

Earth shares a cool phenomenon with Jupiter, Uranus, Neptune, and Saturn: all have observable auroras. NASA created a lovely animation of Saturn's, as well as some cool still images.

Via Hubble/ESA:

This video uses different observations of Saturn: While the observations in the optical, showing the planet itself, were made in 2018, the observations of the auroras were collected in 2017. The video shows how the auroras in Saturn’s northern regions vary over time. The variability of the auroras is influenced by both the solar wind and the rapid rotation of Saturn.

Here's an ultraviolet image captured by the same agencies:
