This galaxy is located approximately 40–45 million light-years from us, in the constellation Pegasus. By the way, NGC 7331 is very similar to our Milky Way in size, shape, and mass.
By classification, it is a Type Ia supernova. This type of explosion occurs in a binary system: a white dwarf pulls matter from a companion star until an uncontrolled thermonuclear reaction is triggered, which destroys the white dwarf.
