A false-color image from the Hubble Space Telescope's STIS instrument showcases Saturn's ultraviolet aurora. Red indicates atomic hydrogen emission, while white shows hydrogen molecules. These auroral displays, towering over 1000 miles above Saturn's clouds, are similar to Earth's and provide insights into the planet's atmosphere and magnetic field.
