Hubble Tracks Bright Auroras on Jupiter

This composite video illustrates the auroras on Jupiter relative to their position on the giant planet. As on Earth, auroras are produced by the interaction of a planet’s magnetic field with its atmosphere. The Jupiter auroras observed by NASA’s Hubble Space Telescope are some of the most active and brightest ever caught by Hubble, reaching intensities over a thousand times brighter than those seen on Earth. Hubble’s sensitivity to ultraviolet light captures the glow of the auroras above Jupiter’s cloud t
