This image shows NGC 4725, a spiral galaxy in which is unusual because it only contains one arm. Most spiral galaxies contain many arms but this one contains just one which appears to form a ring around the galactic core. It is located in the constellation Coma Berenices. Simulations have been run to try and determine how this galaxy was formed, but no conclusive results have been found.
