A spiral galaxy can be described as a type of galaxy characterized by its distinctive spiral arms that wind outwards from its central bulge. These arms are composed of stars, gas, and dust and often contain regions of active star formation. The central bulge is usually made up of older stars and may contain a supermassive black hole. Spiral galaxies also typically have a flat, disk-like structure with a halo of stars and dark matter surrounding it. The Milky Way is an example of a spiral galaxy.
