Galileo Galilei – the first person to observe Saturn's rings, in 1610; Christiaan Huygens – the first to propose that there was a ring surrounding Saturn, in 1655; Giovanni Cassini – discovered the separation between the A and B rings (the Cassini Division), in 1675
An artist's impression of Rhea's rings. The density of the particles is exaggerated greatly to aid visibility. [1] Rhea, the second-largest moon of Saturn, may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk. This would be the first discovery of rings around a moon.
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
Peggy is the informal name for a former moonlet in the outermost part of Saturn's Ring A, orbiting 136,775 kilometres (84,988 mi) away from the planet. The moonlet was discovered by the Cassini Imaging Team in 2013 and it may likely be exiting Saturn's A Ring. [1] No direct image of Peggy has ever been made. [4]
NASA’s James Webb Space Telescope has captured its first near-infrared observation of Saturn, highlighting details in the planet’s atmosphere and rings.
In an image captured by the Hubble Space Telescope, Saturn’s rings display an unexplained phenomenon that looks like spokes moving across its rings.
S/2009 S 1 is a moonlet embedded in the outer part of Saturn's B Ring, orbiting 117,000 km (73,000 mi) away from the planet.The moonlet was discovered by the Cassini Imaging Team during the Saturnian equinox event on 26 July 2009, when the Cassini spacecraft imaged the moonlet casting a 36 km (22 mi)-long shadow onto the B Ring.

Back-illuminated rings of Saturn as seen by Cassini on 15 September 2006. The faint Pallene ring is visible at the bottom left as indicated. In 2006, images taken in forward-scattered light by the Cassini spacecraft enabled the Cassini Imaging Team to discover a faint dust ring around Saturn that shares Pallene's orbit, now named the Pallene Ring.
