PHOTO: ITAR-TASS Saturn’s rings and satellites are much older than previously thought. According to NASA, space data the Cassini probe indicate they are about four billion years. This means that the gas giant revolves around kind of “antique shop” – the ancient celestial bodies that appeared back in the period of the origin of the solar system, at a time when around a young star there was a protoplanetary cloud. Make like that the conclusion to astronomers was allowed by the data of “Cassini” about what is around Saturn has a large amount of water ice. Since Saturn located outside the “snow line” where the water no longer evaporates under the influence of solar radiation, then astronomers concluded that it is an ancient ice that appeared at the time of its inception Solar system. He could not be brought in by comets, because it’s too much. Cassini also collected new satellite data and Saturn’s rings that explain why they are painted in one color or another. For example, powerful geysers on Enceladus color this satellite and nearby rings in white. Other the rings and moons have the reddish hue to which they owe Apparently, meteorites that brought in a large amount of oxide gland. Looking at the pictures of Prometheus and the adjacent rings, experts also suggested that their reddish tint might to say that this satellite was once “blinded” from material rings. “Scientists have been thinking about whether satellites can emerge from particles of rings – since the prevailing theory claimed that rings, on the contrary, are formed from decaying satellites. Their color gives us strong evidence that that the opposite can happen, “said Gianrico Filaccio, employee of the Italian National Institute of Astrophysics.
