The concept that Saturn's rings are made up of a series of tiny ringlets can be traced to Pierre-Simon Laplace, [4] although true gaps are few – it is more correct to think of the rings as an annular disk with concentric local maxima and minima in density and brightness. [2] On the scale of the clumps within the rings there is much empty space.
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.
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as the rings of Saturn, or circumplanetary disks.
Illustration by Elizabeth Brockway/The Daily BeastThe rings of Saturn are one of the most iconic structures in the solar system. Composed of billions of tiny chunks of ice and rock that are as ...
Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14] Giovanni Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. [15] The Sun photographed through a telescope with special solar filter.
Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them. Few missions have visited Saturn: Pioneer 11 and Voyagers 1 and 2 flew by, but Cassini ...
See more on Saturn's rings: No telescope on this planet would ever have been able to see this. Cassini left Earth in 1997 and, in its nearly two decades of exploration, has sent home remarkable ...
He discovered four satellites of Saturn and noted the division of its rings; the Cassini Division was named after him. Giovanni Domenico Cassini was also the first of his family to begin work on the project of creating a topographic map of France. In addition, Cassini also created the first scientific map of the moon. [6]
