A spiral galaxy can be described as a flattened, rotating disk that contains stars, gas, and dust, along with a central concentration of stars known as the bulge. The spiral arms extend outward from the center, giving the galaxy its characteristic spiral shape. The overall structure is often compared to a pinwheel or a whirlpool. In terms of geometry, it can be regarded as a combination of a disk (or a circular shape) with spiral patterns extending from it.
