Saturn's Rings in Ultraviolet

July 8, 2004
From the inside out, the Cassini division in faint red at left is followed by the A ring in its entirety. The A ring begins with a dirty interior of red followed by a general pattern of more turquoise as it spreads away from the planet, which indicates denser material made up of ice. The red band roughly three-fourths of the way outward in the A ring is known as the Encke gap.
