The astronomers from the University of Maryland and Lowell Observatory from the Arizona, are observing the comet C/2012 S1, which may be the brightest comet. For the observation the astronomers are relying on NASA’s Swift satellite to track the comet. The comet will pass near the Sun later this year. By the words of astronomers the approaching will be a dazzling display. The comet C/2012 S1 is supposed to be one of the brightest ever recorder. The astronomers examine the images from Ultraviolet/Optical Telescope, for the making the comet’s initial estimates of the water and dust production. The comet C/2012 S1 can be the brightest comet among all the comets, which the astronomers have noticed during last 50 years in the solar system. The comet gives the chance to astronomers to observe the changes of comet in details and over an extended period. Currently the comet is approaching to the solar system. In the inner solar system the comet will encounter with Mars. In late February, NASA began to collect the information regarding the comet. This comet was found last year by Russian astronomers. The object is contained from icy gas and dust, and it throws off dust and gas when the comet passes near to the Sun, and changes from solid gas. The material is powering by sublimating ice, which reflects sunlight and because of this the comet becomes more brightly. According to the astronomers, the comet’s trip to the inner solar system is for the first time. The comet becomes from the Oort comet cloud, which is composed from a trillion ice bodies of the planetary system. After approaching to the Sun the comet C/2012 S1 will come within 39.9 million miles of Earth on December 26.
