Pierścienie Saturna: Dynamic and Evolving System

Before Cassini, the rings were often viewed a static, ancient structure. The missionn revealed them to a violently active, constantly changing environment. The rings are compose primarily of water ice particles, ranging in size from micrometers to meters, with a small fraction of rocky debris. Collisions, gravitational interactions with moons, and even the infall of microorometeids shape theitur structure at all scales.

Cassini 's imaging cameras captured transident, finger- like facures called quentes; spokes quenquentes; in the B ring - radial clouds of tiny duss parties that seem to form anddissipate over hours.

Titan: A Worlds of Organic Chemistry and Liquid Hydrocarbons

Perhaps no moon in the solar system is more Earth-like in it s surface processes than Titan.
