How do ring galaxies form
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. Hoag's Object, discovered by Art Hoag in 1950, is an example of a ring galaxy. The ring contains many massive, relatively young blue stars, which are extremely bright. … See more Ring galaxies are theorized to be formed through various methods including, but not limited to, the following scenarios: Bar instability A phenomenon where the rotational velocity of the bar in a barred spiral galaxy increases to the … See more • Hoag's Object at Astronomy Picture of the Day.

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.
