Spitzer Discovers Saturn

The new zone extends across the entire Saturn system, and its orbit is tilted 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 to about 12 million kilometers (7.4 million miles). To fill the entire volume of the ring, it would take about a billion-like planet Land, collected 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, temperature is 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, which resembles yin-yang symbol. Astronomer Giovanni Cassini (Giovanni Cassini) first noticed this satellite in 1671, a few years later calculated that the satellite has a dark side, which is now called Cassini Regio (Cassini Regio) in his honor. Ultra- Saturn’s ring could be explained as Cassini Regio (Cassini Regio) has become so dark. The ring is drawn in the same direction as that of Phoebe, while Lapetus (Iapetus), and most of the other rings of Saturn’s moons are moving in the opposite side. According to scientists, some of the dark matter from pulverized long (outer) ring moves inward, toward the Lapetusu, crashing into an ice-covered surface of the satellite, just like the beetles cut into windshield. ‘Astronomers have long suspected a link between Saturn’s moon Phoebe distant and dark matter Lapetusa’ – said of Hamilton. ‘It provides a new ring missing link. ” Verbistser (Verbiscer) with colleagues used the infrared camera, mounted on Spitzer, work in the future (long wavelength) region of the spectrum, the so-called multi-band imaging photometer, to explore the space through small patch of sky in the distance from Saturn, capturing the region inside the orbit of Phoebe.

Astronomers have been suspicious of the fact that Phoebe can make movement in the belt of dust, and, quite naturally, when scientists first cast 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 may not reflect the many 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 were standing in the ring, then you would not understand this “- said Verbistser (Verbiscer). “By focusing their attention on the brilliance of cold dust, which consists of a ring, Spitzer has simplified the task of discovery.
