NGC6946 - Fireworks Galaxy

Image Description and Details :

NGC6946 - Fireworks Galaxy - Constellation Cepheus
NGC 6946 is located in the constellation Cepheus, bordering that of Cygnus. NGC 6946 is a spiral galaxy about 22 million light years away from us. Numerous supernovae have been observed in it, so much so that it is christened the "fireworks galaxy". It is an intermediate galaxy between spiral and barred spiral galaxies with a high level of star formation. It is believed to be a very active galaxy not only due to the presence of numerous nebulae, incubators of stars but also due to the presence of rivers of hydrogen (cold streams) which allow hydrogen to be distributed in such a way as to maintain the formation of new stars . It differs from our Milky Way precisely because of the greater star formation. It was discovered in 1798 by William Herschel, known for having, among other things (he is credited with identifying Uranus), discovered infrared rays.
