Newton's Symphony
..Or Leibniz's punk-rock!!! This is apparently the edge of the Encke Gap - imaged at a couple of hundred meters per pixel last night in the frantic imaging after SOI.
Dark side of the rings, light is diffusely scattered sunlight, dark is void or opaque, and the rippled bizzaro crap in between is anyone's guess. The moonlet Pan is supposed to rummage through these part - I didn't realize that included rucking up the local carpet!!
UPDATE: Peter wonders what the hell I was smoking when I wrote this.
Briefly, "Newton's symphony" - Saturn's rings are basically an enormous gravitational musical instrument, being played by various moons via the father of differentiation's magical force. F=ma, g=GMm/r^2 etc. etc.
Leibniz, the inventor of intergration and the concept of energy, was his close Swedish rival and contemporary- and the complexity and apparent fubarness of the rings suggests melodies distinctly nonclassical.
SOI, is, of course, Saturn Orbit Insertion.
If you look at the stuff between the black (the Encke gap) and the density wave (the parallel lines) it is, well, weird. Cross cutting waveforms at the km scale. They look a bit like actual topographic features - corrugations on the ring plane at small scales. The gap itself is cleared by the 12-km wide moon Pan, which was found in old Voyager images in 1995.
A broader view of the gap is here ; the spiral standing wave is being spawned by Pan - rumoured to have been 20˚ of longitude away when the image was taken.
