<font size="4">Ultraviolet pictures hint at origin of Saturn's rings</font id="size4">
The best view ever of Saturn's rings in the ultraviolet indicates there is more ice toward the outer part of the rings, hinting at ring origin and evolution, say two University of Colorado at Boulder researchers involved in the Cassini mission.
<font size="1">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.</font id="size1">
<font size="1">This image shows the outer C and inner B rings respectively from left to right,
with the inner B ring beginning a little more than halfway across the image. The general pattern
is from "dirty" red particles to the denser ice shown in turquoise as the ringlets spread outward.</font id="size1">
The ring system begins from the inside out with the D, C, B and A rings followed by
the F, G and E rings. The red in both images indicates sparser ringlets likely made of "dirty," and possibly smaller, particles than in the denser,
icier turquoise ringlets.
