This is interesting although apparently the new image taken last month isnt unusual

July 2004

The figures were cropped from two original Cassini spacecraft narrow angle camera images (taken during Saturn orbit insertion on July 1, 2004) and magnified for visibility. The images were then reprojected so that orbital motion is to the left, and Saturn is up. The unseen moonlets lie in the center of each structure.

The novel illumination geometry that accompanies equinox lowers the sun's angle to the ringplane, significantly darkens the rings, and causes out-of-plane structures to cast long shadows across the rings. (The rings have been brightened in this image to enhance visibility.) These scenes are possible only during the few months before and after Saturn's equinox which occurs only once in about 15 Earth years.
Or it's the Annunaki
