If you could see in the UV, and looked at Saturn, its aurorae would look like this. This is the first image of Saturn’s ultraviolet aurora taken by Hubble in October 1997, when Saturn was at a distance of 1.3 billion km from Earth.

The interaction of the solar wind with Saturn's magnetic field induces these aurorae, but only in the UV spectrum—so we can only see it from space.
