By in this stunning image NASA/ ESA Hubble Space Telescope, The Galaxy NGC 2799 (left) is mostly stretched in the middle of the Galaxy NGC 2798 (right).
Due to the influence on each other, such as the interaction of galaxies, which can eventually lead to mergers or unique formations. Already, these two galaxies have probably formed a ly-side reservoir, in which the stars of NGC 2799 appear to fall into NGC 2798 like water droplets.
Galactic mergers can last from several hundred million to a billion years. While one would think that the merging of two galaxies would be catastrophic for the stellar systems inside, the amount of space between the stars means that stellar collisions are unlikely and the stars usually leave each other behind.
