New features found at Saturn's ring by Cassini



. picture A: the left arrow is showing a new diffuse ring inside C ring Maxwell gap. The Maxwell ringlet is indicated by the right arrow
. picture B: a new diffuse ring (left arrow) is seen inside the Huygens gap. Right arrow indicates the Huygens ring. The Huygens gap is located between the B-ring outer edge and dark bands of the Cassini division
. picture C: ringlets (arrows) inside the Encke gap. The thickest is coincident with Pan's orbit
. picture D: material is expending 250 miles (400 km) beyond A-ring outer border and two diffuse rings (R/2004 S1 or "Atlas ring", 190 mi (300 km) wide, left, at the orbit of Atlas; R/2004 S2 right immediately inside Prometheus' orbit) are seen. It might that such rings be of the Jovian type, hence intermingling with the classical Saturnian ring!. The elliptical orbit of Prometheus had the moon clean a region between R/2004 S2 and the inner boundary of the F ring
. an yet unseen moon might be located inside the 26 mi (42 km)-wide Keeler gap where spikes are indicative of it (picture E)
The material of such new rings may derive from moons linked to them (like the "Atlas ring" or the main Encke ringlet (with Pan)), or be created by various interactions between various materials and moons (still to be found) inside a gap and a sheperding moon also inside of it. All such ring particles are of the order of less of a micrometer, hence non-gravitational forces may also interact

The outer edge of the A ring (left) is mottled due to gravitational disturbances as Pan is sculpting the inner edge of the Encke gap (right)
