The galaxy NGC 6946 is about 22 light years away. This May, it has been observed in one of his arms, the death of a massive star as a supernova (SN 2017eaw), which may be indicated in the picture. In fact, in the last 100 years there have been at least 10 supernova in this galaxy, which gives well-deserved name “Galaxy fireworks.”
