A photo from open sources Published the first color image of a comet Churyumova – Gerasimenko – on it a comet of gray-red color. Snapshot taken in November, the image is blurry, as between the two neighboring exposures, the comet moved in the frame. Previously scientists stated that the color of the comet is black, and all pictures were taken in monochrom. An OSIRIS device installed on a comet can do only black and white shots as it has no color sensors. However, thanks to its disk with filters along the wavelength of light, which is reflected from the comet, you can determine the color. As reported RT, it was previously reported that comet color in ultraviolet radiation were black. After December 15th at the American Congress a geophysical union will be presented with a clearer image and scientists will discuss the color of the comet. Rosetta probe regularly sends pictures of a comet. For example, this is a black and white image, mounted from four shots of the NAVCAM camera, 30 were received November 2014
