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.
What are Saturn's rings made of? ... The main rings are A, B and C, with D, E and F being more recently discovered. There is also a very faint ring in the orbit of Saturn's moon Phoebe.
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]
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’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.
NASA’s James Webb Space Telescope has captured its first near-infrared observation of Saturn, highlighting details in the planet’s atmosphere and rings. Saturn’s rings shine in new Webb ...
Porco's 2007 TED talk, "The Human Journey," detailed two major areas of discovery made by the Cassini mission: the exploration of the Saturnian moons Titan and Enceladus. In her introductory remarks, Porco explained: So the journey back to Saturn is really part of, and is also a metaphor for, a much larger human voyage.
