You go out into the street on a cold night, hoping to see in the clear winter sky at least a small speck of comet. You must be surprised that the tiny green-blue reflections can be viewed only in the lens of a telescope. But this is nothing compared to the capabilities of an astronomer, who, plus everything else, is also an astronaut. After all, it is up to him to fly around 17 thousand miles around the Earth in just one hour and see the comet from a closer distance.
Posted on Twitter by NASA astronaut Terry Virts, who arrived at the international space station in November. Presumably, this space survey is one of the most successful pictures of the comet, since the picture was taken from the closest possible distance. In the absence of an atmosphere, it is hard to catch the comet's glow, but Virts did manage to bring the image closer and take a picture of green reflections. The green cloud consists of gas and dust. They surround the nucleus, reflecting sunlight, so the comet glows dull green. Of course, you cannot view a comet as well as this astronaut, but, nevertheless, you can see the comet's green light through a telescope.
