Explanation

Our Milky Way galaxy is a flat spiral galaxy with arms extending from a central bulge. It resembles a rotating pinwheel about 100,000 light-years across but only about 1,000 light-years thick. This flat spiral structure is typical of large galaxies, distinguishing them from elliptical (round ball), irregular (pretzel-like), or ring (doughnut-shaped) galaxies.
