Voyager image of the rings of Saturn The faint colour of the rings has been enhanced in this image The Cring bottom left the particles in the Cassini Division reflect short wavelengths better appear dark blue The Bring changes colour smoothlyfrom the outside bluegreen to the inside orange which reflects longer wave lengths most efficiently There is a sharp change in colour between the Bring the Cring outside the black band of the Cassini Division The ice of the particles composing the rings is probably coloured either by impurities or by damage to its crystalline structure from highspeed subatomic particles trapped in Saturns magnetic field
