New evidence from Cassini say about that pristine picture related to the formation of the solar system, is stored in the Saturn system. The giant planet, its moons and rings similar to Space antique shop, where strikingly presented initial phase of the structure of planetary and satellite facilities.
The presence of shading surfaces of bodies in the Saturn system is certainly present - because of their age, more than 4 billion years old! For such a long time on the outer surface of the body spilled substance with a slight amount of staining the surface lightly, and sometimes when forming asterioidnom Impact crater - mark hitting the surface of the body. Dzhanriko Filakkone (Italian National Institute for Astrophysics), lead author of the study of Saturn and his colleagues claim that this is quite a distant planet lifts the veil of secrecy over the processes of chemical and physical evolution in the early formation of a planetary system around the Sun.
Understanding evolution experts believe may not in the study of specific satellites alone or rings. It is mandatory to study the interaction of related objects in the system, and their mutual influence. Thus, the staining of rings and moons mostly superficial, evidenced by the testimony kartografiruyuschego spectrometer operating in the visible and infrared regions of the spectrum, the tool is called VIMS. It provides information on how to Saturn system distributed ice and toning color attributes are considered non-aqueous, possibly organic material.
In the infrared region of the VIMS instrument data reveal a large amount of water ice, it is so much to consider it externally introduced by comets simply unrealistic. Experts say that this supply of ice was present initially in the formation of the solar system, because the orbit of Saturn goes beyond the snow line, where water exists only in the crystalline phase, it can be regarded as a cosmic freezer because the ice there perfectly preserved, it is practically eternal.
Conditions in the outer solar system favor conservation of water ice (think of it as freezer space). Inside the snow line can be sublimation of ice and evaporation of water droplets under the influence of solar radiation. Colour on the part of the rings and moons of Saturn is related to their location in the Saturn system. Enceladus whitens neighborhood by huge ice geysers emitting into the environment fine water ice. Removed from Saturn#39;s moons okrashivaet reddish Phoebe.
There is speculation that Phoebe has come from the Kuiper belt, it is qualitatively different in composition and scatters around the reddish dust, from which satellites Hyperion and Iapetus also slightly red. Meteor showers that may spill from outside the system of Saturn, too, could give a reddish tinge to some parts of the rings, mostly ring B.
Presumably, the reddish color due to their oxidized iron or polycyclic aromatic hydrocarbons, of which there may be more complex organic molecule. Small satellite Prometheus, the form of which is described as kartofeleobraznaya, has a similar reddish coloring of the adjacent parts of the coil system near the Prometheus.
Other satellites in the region traditionally white. Co-author Bonnie Buratti of NASA#39;s Jet Propulsion Laboratory has put forward the hypothesis that Prometheus has concentrated material rings. It is generally believed that the ring particles are milled on the orbits of the satellites, but Buratti involves the reverse process - the concentration of satellite Premeteya. Surprisingly multifactorial and complex, jewelry organized system of Saturn#39;s intriguing to researchers as sohranny reserve early phase of the creation of the solar system. Explanation of its features - an interesting challenge planetary scientists.
