Seeing the Shadow of Rings around a “Super Saturn”
Astronomers think they have found a planet that has a giant set of rings around it, over 200 times larger than the rings around the planet Saturn. The planet is young enough that moons may be forming out of the material of the rings, and we are seeing the shadows of the rings here on Earth. We are now looking for other planets that have giant rings around them, and we may see rings in 2017 arou...
متن کاملSynchronization mechanism of sharp edges in rings of Saturn
We propose a new mechanism which explains the existence of enormously sharp edges in the rings of Saturn. This mechanism is based on the synchronization phenomenon due to which the epicycle rotational phases of particles in the ring, under certain conditions, become synchronized with the phase of external satellite, e.g. with the phase of Mimas in the case of the outer B ring edge. This synchro...
متن کاملOptical Properties of Saturn ' S Rings : I . Transmission
All existing observational data relating to the transmission properties of Saturn's rings are discussed. Fromsuch data the optical thickness of the crape ring is determined as a function of its distance from the planet.Limiting values for ring B and a new value for the inner radius of ring B are established. The shape of thepressure curve of a gas cloud evidently associated with rin...
متن کاملCassini Imaging Science: initial results on Saturn's rings and small satellites.
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem (ISS) during the first 9 months of Cassini operations at Saturn have produced many new findings. These include new saturnian moons; refined orbits of new and previously known moons; narrow diffuse rings in the F-ring region and embedded in gaps within the main rings; exceptionally fine-scale ring structur...
