Spiral structures, often described as resembling a whirlpool, are a common morphological characteristic observed in many types of galaxies. This rotational pattern is primarily caused by the distribution of matter—including stars, gas, and dust—which orbits the galactic center in a non-uniform manner. The density waves that give rise to these spiral arms are believed to be points of enhanced star formation, as the gravitational interaction within the galactic disk compresses interstellar gas, triggering the birth of new stellar populations. The stability and persistence of these arms are influenced by the galactic rotation curve and the overall mass distribution of the central bulge, creating a dynamic visual representation of the galaxy's rotational physics.
