UGC 2369 taken by Hubble Space Telescope

A tenuous bridge of gas, dust and stars can be seen connecting the two galaxies, created when they pulled material out into space across the diminishing divide between them.^[3] Interaction between galaxies is not an uncommon event, however, two similarly sized ones merging is rare. The images released by NASA show both the galaxies distorting as they pulled closer. In the images, a thin bridge of gas, dust and stars can also be seen. The ridge was developed when the gap between both of the galaxies started diminishing.^[4]
