This image from NASA’s Cassini spacecraft shows Saturn and its rings. Six of Saturn’s moons make a faint appearance in this image: the ice-covered moon Enceladus can be seen at the 1 o’clock position; directly below Enceladus, just outside the F ring (the thin, farthest ring from the planet seen in this image) lies the small moon Epimetheus; following the F ring clock-wise from Epimetheus, the next moon seen is Janus; at about the 4:30 position and outward from the F ring is Mimas; inward of Mimas and still at about the 4:30 position is the F-ring-disrupting moon, Pandora; moving around to the 10 o’clock position, just inside of the F ring, is the moon Prometheus.

This Cassini view shows four dusty strands of Saturn’s F ring: the central strand is the core of the ring; the other strands are not independent at all, but are actually sections of long spirals of material that wrap around the gas giant; the material in the spirals was likely knocked out from the F ring’s core during interactions with a small moon.

This Cassini image features a density wave in Saturn’s A ring (at left) that lies around 83,575 miles (134,500 km) from Saturn. Density waves are accumulations of particles at certain distances from the planet. This feature is filled with clumpy perturbations, which researchers informally refer to as ‘straw.’ The wave itself is created by the gravity of Saturn’s moons Janus and Epimetheus, which share the same orbit around the gas giant. Elsewhere, the scene is dominated by ‘wakes’ from a recent pass of the ring moon Pan. The image was taken in visible light with Cassini’s wide-angle camera on December 18, 2016. The view was obtained at a distance of approximately 34,000 miles (56,000 km) from the rings and looks toward the unilluminated side of the rings.

This view from Cassini was obtained about half a day before its first close pass by the outer edges of Saturn’s main rings during its penultimate mission phase. The view shows part of the giant, hexagon-shaped jet stream around the planet’s north pole. Each side of the hexagon is about as wide as Earth. A circular storm lies at the center, at the pole. The image was taken with Cassini’s wide-angle camera on Dec. 3, 2016, at a distance of about 240,000 miles (390,000 km) from Saturn. Image credit: NASA / JPL-Caltech / Space Science Institute.
