WebThe youngest stars form in gas-rich arms, while older stars can be found throughout the disk and within the bulge and halo. Both the Milky Way and the Andromeda galaxies belong to a subtype known as barred spirals, which make up two-thirds of the group. Barred spirals sport ribbons of stars, gas, and dust that cut across their centers. Some 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. See more A ring galaxy is a galaxy with a circle-like appearance.
