	A '''ring galaxy''' is a [[galaxy]] with a ring-like appearance. The ring consists of massive, relatively young blue stars, which are extremely bright. The central region contains relatively little luminous matter. Some [[~~School:~~Astronomy\|astronomers]] believe that ring galaxies are formed when a smaller galaxy passes through the center of a larger galaxy. Because most of a galaxy consists of empty space, this "collision" rarely results in any actual collisions between stars. However the gravitational disruptions caused by such an event could cause a wave of star formation to move through the larger galaxy. Others think that rings are formed around some galaxies when external accretion takes place. The star formation would then take place in the accreted material because of the shocks and compressions of the accreted material. There might be a link between ring galaxies and polar ring galaxies.		A '''ring galaxy''' is a [[galaxy]] with a ring-like appearance.
