The Hubble telescope has taken the first picture of bright aurorae at Saturn's northern and southern poles [top picture]. The picture at the bottom was taken in visible light.
Hubble's far-ultraviolet-light image resolves a luminous, circular band centered on the north pole, where an enormous curtain of light rises as far as 1,200 miles (2,000 kilometers) above the cloud tops. This curtain changed rapidly in brightness and extent over the two-hour period of observations.
