spaceplasma:This animated series of images of Saturn’s F Ring was acquired by Cassini on June 10, 2009. “Shepherd” moons Prometheus (inner) and Pandora (outer) pass by, alternately smoothing and disturbing the particles that make up the ring. Kinks, knots, wakes and disturbances are apparent in the thin ring as it rotates. Credit: NASA/JPL/Space Science Institute -- source link
