Saturnโs Rings are one of most incredible features in the solar system. ย Who are we kidding, besides life on Earth, Saturnโs rings are the single most fascinating macro-objects in the universe. ย Just look at them. ย How are they suspended there, in one plane, with that spacing, and those occasional spokes? ย Unreal…
(note: ย all images taken by the Cassini-Huygens spacecraft sent there to investigate Saturn and itโs rings)
1. ย The Rings Have Their Own Atmosphere: ย Flying close by the rings, theย Cassini-Huygensย spacecraft observed enhanced levels of oxygen gas in the ring system. Researchers believe water from the rings is broken up into its components, hydrogen and oxygen; the hydrogen dissipates while the oxygen stays.
2. ย Saturnโs E Ringย (made of microscopic material)ย is Absorbingย Cryovolcanic Gases Erupting from Saturnโs Moon Enceladus: ย Cryovolcanos erupt water, methane, CO2,and ammonia instead of molten rock. ย The gases that Enceladusโ cryovolcanos eject is pumping material into the E Ring of Saturn. ย The whispy, gassy E Ring absorbs these erupted material and grows itโs ring.

3. ย Saturnโs Rings Can Disappear: ย As Saturn circles the sun (once every 29.5 years), the angle at which we here on Earth view its rings changes. Twice during each circuit, the rings are edge-on as viewed from Earth, making them seem to disappear. These ring-plane crossings vexed Galileo (“Has Saturn swallowed his children?” he asked during a ring plane crossing in 1612), but they’re a killer time for astronomers to study Saturn for new moons and other features without the glare from the ring.

4. ย Composition of the Particles in the Rings = mostly water ice with trace amount of some silicate materials.
5. ย Outermost ring:ย E Ring is 111,847 to 298,258 miles, from Saturn’s center
6. ย Likely causes of gaps in rings:ย Gravitational pull of “shepherd” moons, resonance effects between ring particles and moons
7. ย Size of particles in rings:ย anywhere from 1 cm to several meters, with some larger objects and “moonlets”
