Rainbows and Movies

After this morning’s post on Cassini’s tenth anniversary, the JPL/NASA web site for the probe released a slew of fantastic images and movies. One of my favorite images is the bit of “rainbow” on Saturn’s ring. Explained here:

The opposition effect, a brightness surge that is visible on Saturn’s rings when the sun is directly behind the spacecraft, is captured here as a colorful halo of light moving across Saturn’s sunlit rings. The rainbow of color seen here is actually an artifact and a by-product of the spot’s movement and the way the color image was produced.

This video reminded me of Dumbledore and his pensieve. It shows the shepherd moon Prometheus pulling a strand of material after a brush with the F-Ring. The moon is slightly bigger than Rhode Island, to give you an idea of perspective.
