Saturn's rings, beautiful and mysterious, are an optical illusion on a cosmic scale. Far from solid, they're actually a blizzard of water-ice particles mixed with dust and rock fragments. The Cassini mission has already captured amazing views of this dynamic system.

With giant Saturn hanging in the blackness, the Cassini spacecraft viewed the rings as never before, revealing previously unknown faint rings and even glimpsing our home world.
