I hope you don't mind an occasional astro-geology image.

I've seen about 20-30 images from Cassini (and a few from Galileo) that reminded me of ol' Chesley.

It always amazes me how sharp and distinct (narrow!) the rings are.

Funny too, in all of the 50's and 60's science fiction stories, rings would be drawn around one planet (never two or three!) on the cover of "foreign" solar systems.

But NO ONE EVER assumed rings would be found on several different planets in our own solar system.

There must be some high-mathematical orbital dynamics reason for that, but yes, they must be only a few km wide.

Have you seen Cassini pictures of the moonlets that make the gaps in the rings? There's one (and a movie) that shows waves in the rings created by the moon as it goes by. Wild.

For a few, not even kilometers thick.

Others are thicker: probably due to the moons being closer.

Ring Name: D
Distance*: 68,000 km
Width: 8,500 km

Ring Name: C
Distance*: 74,500 km
Width: 17,500 km
Mass: 1.1 x 1021 kg
Albedo: 0.1-0.3

Ring Name: B
Distance*: 92,000 km
Width: 25,500 km
Thickness: 0.1 km - 1 km
Mass: 2.8 x 1022 kg
Albedo: 0.4-0.6

Ring Name: Cassini Division
Distance*: 117,500 km
Width: 4,700 km
Mass: 5.7 x 1017 kg
Albedo: 0.2-0.4

Ring Name: A
Distance*: 122,200 km
Width: 14,600 km
Thickness: 0.1 km - 1 km
Mass: 6.2 x 1021 kg
Albedo: 0.4-0.6

Ring Name: F
Distance*: 140,210 km
Width: 30 km - 500 km
Albedo: 0.6

Ring Name: G
Distance*: 165,800 km
Width: 8,000 km
Thickness: 100 km - 1,000 km
Mass: 1 x 1017 kg

Ring Name: E
Distance*: 180,000 km
Width: 300,000 km
Thickness: 1,000 km - 30,000 km
Mass: 7 x 108 kg

* The distance is measured from the planet center to the start of the ring.

I just wanted to alert all of you who corresponded on this thread that JPL has a color version of the picture and a small and large Quicktime movie of the flyby.

Multimedia - Images - Moons - Dione

Ice Moon Rendesvous (Videos)

They've also got this shot that I first saw in the video, of Dione with Saturn lurking in the background:
