Not long after NASA's Cassini mission arrived at Saturn in 2004, researchers realized that the planet's rings were oscillating strangely. Instead of single waves, which are predicted by existing theory, the spacecraft revealed clusters of small waves that could be explained by the presence of gravity waves in the deepest part of the planet's interior.
On rocky planets like Earth, disturbances beneath the planet's surface can move as a wave, traveling through the planet's interior and through its surface.... Eventually, interference from other traveling waves can create a standing wave pattern spanning the entire planet.
The same process occurs on Saturn...Most of the time, their orbit is calm and orderly, with occasional collisions. Scientists have known for decades that the ring particles can be affected by the gravitational pull of the planet's 82 moons.While ring seismology was proposed in the early 1990s, it wasn’t until a spacecraft spent time orbiting the planet that the idea could be put into play.
Cassini revealed that Saturn's rings were also subjected to the tremors of the planet's oscillating gravitational field. The spacecraft characterized more than 20 waves in the Saturn's ring system caused by the heart of the planet. The interactions occur only in special places in the rings, but the results can be "dramatic," according to Mankovich. The effect is small, with the waves only about a single kilometer from peak to peak, while the rings span nearly 180,000 miles (300,000 km).
Understanding what's going on deep in Saturn's heart is very much an ongoing process. According to Mankovich, ring seismology favors a thick stable region that makes up roughly a quarter of the planet's radius. That's somewhat at odds with understanding gleaned from the planet's magnetic field, which favors a narrow, stable region only 5 to 10% of the planet's interior.

I was hoping Saturn would be more stable than this.
At least they’re not honking.
*ping*
I had this album in my early teens. I remember listening to it at full volume while my parents were out shopping. It’s totally wack.
I do not believe in astrology but here is what ‘those guys’ believe about Saturn:
Saturn, is the ruler of Capricorn. In Greek Mythology, Cronus was one of the Titans, and the father of Zeus. Cronus ate his children to prevent himself from being dethroned as the King of the Gods. That is, until his wife, Rhea, tricked him into swallowing a stone when Zeus was born.
In astrology, Saturn is associated with restriction and limitation. Where Jupiter expands, Saturn constricts. Although the themes of Saturn seem depressing, Saturn brings structure and meaning to our world. Saturn knows the limits of time and matter. Saturn reminds us of our boundaries, our responsibilities, and our commitments. It brings definition to our lives. Saturn makes us aware of the need for self-control and of boundaries and our limits.
Saturn Symbol GlyphSaturn is often associated with our fathers or father/authority figures. In childhood, the discipline, rules, and regulations imposed on us by our authority figures–from parents, teachers, and the like–were not always pleasant, but they actually helped us to understand the world around us. Similarly, Saturn’s lessons actually help us to grow.
In the chart, the position of Saturn by sign and house reveals our own limitations, fears, and sense of responsibility. Saturn brings definition, and often limitation, to the planets it aspects.
And so, the wack begins...

Farnsworth: Eureka!
[Fry, Leela and Bender run in.]
Fry: Did you build the Smellescope?
Farnsworth: No, I remembered that I’d built one last year. Go ahead, try it. You’ll find that every heavenly body has its own particular scent. Here, I’ll point it at Jupiter.
[Fry sniffs.]
Fry: Smells like strawberries.
Farnsworth: Exactly! And now Saturn.
[Fry sniffs.]
Fry: Pine needles. Oh, man, this is great! Hey, as long as you don’t make me smell Uranus.
[He laughs.]
Leela: I don’t get it.
Farnsworth: I’m sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.
Fry: Oh. What’s it called now?
Farnsworth: Urectum. Here, let me locate it for you.
No. It’s driven by the alignment of the center of mass of the Sun with the center of mass of the solar system as driven by the position of Jupiter and Saturn. Don’t these people understand basic astrophysicist? Sheesh.
If the rings of Saturn are ringing like a bell, what are the rings of Uranus doing?
“If the rings of Saturn are ringing like a bell, what are the rings of Uranus doing?”
Those are dingleberries and make a higher pitched ring.
burning like hell
Somewhere I read that Saturn’s rings will last for only another 100-200 thousand years.
They are stunningly beautiful... but only for a moment, cosmology-wise.
Johnny B Goode could play a gas giant planet just like ringing a bell.

Just don’t mistake them for Klingons.
Klingons are lower toned and usually hard to hear.
To paraphrase a former President, at a certain point you don't need any more moons. No planet needs 82 moons. How about sharing some with Venus or Mercury?
One of Kepler’s big projects was the music of the spheres. I don’t know if any progress has been made on that since his time.
Ringing? Not in space they ain’t...
