Spitzer space telescope transferred pictures of a C/2012 S1 comet of ISON. It becomes the brightest object in the night sky of Earth after the Moon in November, 2013 when it will dive into the Sun to Earth and will take place in dangerous proximity from the star photosphere. The comet of C/2012 S1 comet was open in September, 2012 by the Russian astronomers. The comet in November, 2013 will pass at distance in 1,2 million kilometers from the Sun. At this time brightness of a comet can reach brightness of the full Moon, and it, probably, becomes the brightest in a decade.
In December the comet will pass at the minimum distance from Earth, which is about 0,4 radiuses of a terrestrial orbit. Currently the comet is at distance in 3,3 astronomical from the Sun, between orbits of Jupiter and Mars. While it remains invisible to a naked eye, however land and orbital telescopes watch long ago it in the optical and infrared range. So, in April, 2013 a telescope Hubble received pictures of this comet when it was in an orbit of Jupiter. In June, 2013 the telescope was connected to supervision over ISON Spitzer space telescope which received some pictures of a comet in the infrared range, on length of waves 3,6 and 4,5 microns. Images on different lengths of waves allowed scientists to receive the “blank” image of a kernel of a comet which disappeared earlier the thermal radiation of a dust in “tail” of this heavenly body. According to specialists of NASA, these photos already brought considerable opening. On them is visible the atmosphere of C/2012 S1 comet made of molecules of neutral gases. Scientists believe that it consists generally of carbonic acid which disappears from ices in a comet kernel in process of its approach to the Sun.
