Hubble has identified two bright supernovae

In space is a barred spiral galaxy called NGC 3583, photographed by the NASA / ESA Hubble Space Telescope. This is a barred spiral galaxy with two twisting arms in the Universe. This galaxy is located 98 million light years from the Milky Way. Two supernovae exploded in this galaxy, one in 1975 and another, more recently, in 2015.

There are several ways in which the supernova can form. In the case of these two supernovae, the explosions evolved from two independent binary star systems in which the stellar remnant of a Sun-like star, known as a white dwarf, was collecting material from its companion star.

At this point, the star collapsed inward before exploding outward in a brilliant supernova. Two of these events have been spotted in NGC 3583, and although they are not visible, we can still admire the frightening symmetry of the galaxy.
