Spitzer Detects The Largest Ring Of Saturn

The new zone extends across the entire Saturn system, and its orbit is tilted at an angle of 27 degrees to the plane of the main rings of Saturn. Mass of a substance that forms a ring starts at a distance of about six million kilometers (3.7 million miles) from the planet and extends outward about 12 million kilometers (7.4 million miles). To fill the entire volume of the ring, it would take about one billion-like planet Land put together. One of the most distant moons (satellites) of Saturn, Phoebe, drawn within the newly discovered rings, and, perhaps, is the source of the substance that makes up the ring. Ring rather sparse, consisting of scattered far apart the particles of ice and dust. Infrared sensors-eye telescope, Spitzer failed to recognize the brilliance of cold dust, the temperature of which only about 80 degrees Kelvin (minus 316 degrees Fahrenheit). This discovery may help solve the age-old riddle of one of Saturn's moons.

Lapetus (Iapetus) has a strange look – one side of his bright, and the other – very dark, in accordance with the principle that resembles yin-yang symbol. If you have read about search already – you may have come to the same conclusion. Astronomer Giovanni Cassini (Giovanni Cassini) first noticed this satellite in 1671, a few years later calculated that a satellite has a dark side, which is now called Cassini Regio (Cassini Regio) in his honor. Xi'an Saturn's ring could explain how the Cassini Regio (Cassini Regio) has become so dark. The ring is drawn in the same direction as Phoebe, while Lapetus (Iapetus), the other rings and Saturn's moons, most are moving in the opposite side. According to scientists, some dark dusty material from the far (outer) ring moves inward toward Lapetusu, crashing into the icy surface of the satellite, just as the beetles cut into windshield.

'Astronomers have long suspected a link between distant satellite of Saturn Feboy and dark matter Lapetusa' – Hamilton said. 'It provides a new ring missing link'. Verbistser (Verbiscer) with colleagues used the infrared camera, mounted on Spitzer, working in the future (long) region of the spectrum, the so-called multi-band imaging photometer, to explore the space through a small patch of sky in the distance from Saturn, capturing the region inside the orbit of Phoebe. Astronomers have been suspicions about the fact that Phoebe can perform the movement in the belt of dust, and, quite naturally, when the researchers threw the first look at the data obtained by Spitzer, a cloud of dust appeared. The ring would be difficult to see with telescopes operating in the visible spectrum. The relatively small number of particles in the ring can not reflect much visible light, especially outside of Saturn, where the sun set is rather weak. 'The particles are at a great distance from each other, that if you stood in the ring, then you would not even understand this' – said Verbistser (Verbiscer). 'By focusing its attention on the brilliance of cold dust, which is a ring, Spitzer has simplified the task of discovery. "
