Named for their shape, spiral galaxies are the most common type of galaxy in the universe. Of all the known galaxies in the universe, 77% of them are classified as spiral galaxies. These types of galaxies are classified by their 3 main components – a disk, bulge, and halo. The bulge is housed at the center of the galaxy.
