 Here we are zooming into Markarian 266. The odd structure of this galaxy is due to the fact that it is not one galaxy, but two, in the process of a galactic collision. It is composed of two disc galaxies whose nuclei are currently just 13,000 light years apart. Their constituent gas, dust, and stars are swirling together, igniting newborn stars in bright star formation regions across the galaxy. In addition, each merging galaxy contains an active galactic nucleus, or gas and other debris are fed into supermassive black holes.
