AM 2353-291
A fortuitous observation of two smooth colliding galaxies which happen to host a type Ia supernova that erupted at least 5 days prior. SN 2019fkq can be seen as a bright pinpoint nestled between the cores of the two bright galaxies. Also visible in the left galaxy is a disk of dust encircling the nucleus, and numerous globular clusters are scattered about.
With the supernova measured at a redshift of .045, that puts these two galaxies at about 612 million light years away, and around 230000 light years across at the widest point. Two Milky Ways could fit across them.
