In outer space, there is a real challenge for astronomers - IC 342. This is a bright galaxy, located near the equator of our galaxy. In this area, the space is dense, filled with hot gas, bright stars and a shading dust cloud. To view the spiral, one has to wade through various objects in the Milky Way. Due to such a complex process of observation, it became known as a “hidden galaxy”.
It differs in brightness and proximity. She could have been detected first, if not for the dust haze. It has a vigorous activity, accompanied by a variety of colors. An excellent mixture of hot blue regions of stellar birth, as well as cool red gas lines and dark dust streaks can be noted. In 2003, it turned out that it has a HII nucleus - the presence of ionized hydrogen, which provokes the formation of stars.
