Saturn's Aurora: Changes During Jan. 8-30, 2004 (Annotated)

About this video
Duration: 4 seconds

NASA's Hubble Space Telescope Imaging Spectrograph took a series of snapshots of Saturn's aurora dancing in the sky. The ultraviolet images were taken on Jan. 8, 10, 12, 14, 16, 18, 20, 21, 23, 24, 26, 28 and 30, 2004. This dissolve squence shows the aurora appearing as a ring of light circling the planet's polar ring. Collisions with atoms and molecules make the gases in the planet's atmosphere glow in visible, ultraviolet, and infrared light.
