This is a photograph of the edge of one of Saturn's rings, looking down from above. Those spiky dark shapes are shadows. Shadows of giant towers of ice and dust grains clumped together that rise up to three *kilometres* above the 10-m thick rings.

I do not know. Certainly we (the royal we) understood that so-called ring shepherds cleared the empty paths in the rings (the "gaps") through gravitational interactions. But whether it was suspected that such clearing piled up ring material into giant towers along gap margins, I don't know.

Everything about the rings is so interesting, but honestly, I'm regularly amazed at how thin they are. Thank you for all of your great posts!

No. I mean, the pieces are solid(ish), but they're not really physically connected to each other. So it would be like trying to walk on a particularly aggressive cloud

This is NASA Photojournal image PIA11668, taken by the Cassini spacecraft on 26 July 2009. At the time, the Sun was almost exactly aligned with the rings, enabling Cassini to image the shadows from these icy towers. The towers themselves are hard to see, pointing almost directly up at the camera.

No. They'd fall apart like a shitty Soviet car. Plus you'd accelerate towards the ring plane and start to be shredded by all the little dickhead particles. You'd die in like, four different ways. You would, however, probably get a school named after you.

No, no! They're countless septillions of small pieces of ice and rock dust. They're totally not solid. (The bits what comprise them are, and they'll shred you yessir.)

Presumably to the gravitic centre of Saturn along which the rings must be aligned so on either side of the ring there must be a very small component of the attraction acting in the direction of the plane of the rings - thus down. I guess?!? 🙂
