Apr 23, 2008 · The complex structure of Saturn's quirky F ring is unfurled in this mosaic made up of images taken by NASA's Cassini spacecraft. The mosaic covers 255 degrees of longitude within the F ring, which represents about 70 percent of the ring's circumference around Saturn.

May 10, 2024 · One of the stranger planetary rings is Saturn’s narrow, clumpy F ring, lying just outside the main rings, in a region disturbed by chaotic orbital dynamics. We show that the F ring has a stable “true core” that dominates its mass and is confined into discontinuous short arcs of particles larger than a few millimeters in radius.

Nov 1, 2005 · Nearly all isolated narrow rings are found around the ice giants, but an exception is Saturn's F ring — the closest and, accordingly, best-studied archetype. Located just 3,500 km exterior to...

Jul 11, 2013 · Saturn’s F ring does not sit still. Located on the outermost edge of the planet's many planetary rings, it wriggles and writhes, morphing into a slightly different shape at every turn. These movements are no accident. They’re the result of moons—sometimes called shepherds—passing by the ring.

Jun 9, 2008 · Multiple tenuous strands flank the brilliant core of Saturn's F ring. These delicate, flanking ringlets wind through the F ring, creating a tight spiral. This view looks toward the sunlit side of the rings from about 35 degrees below the ringplane.

May 25, 2000 · Saturn's F, or outermost ring was photographed from the un-illuminated face of the rings by Voyager 1 at a range of 750,000 kilometers (470,000 miles). Complex structure is evident, with several components seen. Two narrow, …

Aug 18, 2015 · The mystery behind Saturn's weirdest ring, the F ring, and its two shepherd moons, Pandora and Prometheus, has been solved. An ancient collision caused it, scientists say.

Aug 28, 2015 · The F ring, Saturn's outermost ring, is perhaps the most active ring in our solar system, with features changing on a timescale of hours.

Apr 23, 2008 · Ring scientists now understand a great deal about what causes the various features in the ring. In addition to the powerful perturbing effect of the moon prometheus (PIA07750), there is thought to be a population of small objects in the F-ring region that interact with the ring's core to produce the structures seen (see PIA07716).

Oct 9, 2012 · The Cassini spacecraft captures Saturn’s ever-changing F ring, showing its bright core, another strand of ring material, and a breakaway clump of material close to the core. The F ring core is the brightest strand that stretches across this image. The clump is the bright, short linear feature adjacent to the core near the right side of the image.
