Saturn’s rings are not only a beautiful and enduring symbol of space, but astronomers’ best local laboratory for studying phenomena in thin cosmic disks like those where planets formed. All the giant planets have ring systems. Saturn’s are the biggest and brightest.

Nature, 2009
Most planetary rings in the Solar System lie within a few radii of their host body, because at these distances gravitational accelerations inhibit satellite formation. The best known exceptions are Jupiter's gossamer rings and Saturn's E ring, broad sheets of dust that extend outward until they fade from view at five to ten planetary radii.

Space Science Reviews, 1975
This paper reviews observations of the rings of Saturn at visual, infrared, and radio wavelengths. Critical assessments are made of attempts to derive the physical characteristics of the rings from these measurements. A discussion is also given of the origin and evolution of the rings.

Are Saturn’s rings actually young?
Nature Astronomy, 2019Spectacular results from Cassini’s Grand Finale have provided constraints on the characteristics and evolutionary processes of Saturn’s rings. These results have been interpreted as proof that the rings are much younger than the Solar System, dramatically changing our view of the origin of the whole Saturnian system and attracting the attention of ...

The article focuses on research on rings discovered larger than that of Saturn planet. Topics discussed include discovery of a gargantuan planetary ring system by astronomers that is some 200 times larger than Saturn ring, collaboration of professional and amateur astronomers to study the system in detail and models suggesting that rings harbor a Mars ...

Saturn’s ring temperatures at equinox
Icarus, 2013Abstract Modeling the thermal emission of Saturn’s rings is challenging due to the numerous heating sources as well as the structural properties of the disk and of the particles that are closely related. At equinox, however, rings are externally heated by Saturn alone and the problem is somewhat simplified. We test the abilities of our current models

Saturn's rings in the thermal infrared
Planetary and Space Science, 2003Abstract This paper reviews our current knowledge of Saturn's rings’ physical properties as derived from thermal infrared observations. Ring particle composition, surface structure and spin as well as the vertical structure of the main rings can be determined. These properties are the key to understand the origin and evolution of Saturn's rings. Ring
