Galaxy morphological classification is a method used by astronomers to categorize galaxies based on their visual structure and physical arrangement. These classifications typically divide galaxies into several major types, most notably spiral, elliptical, and irregular. Spiral galaxies are characterized by distinct, rotating arms of star formation originating from a central bulge, while elliptical galaxies are generally smooth, featureless, and possess a more random distribution of stars, often appearing more spheroidal. Irregular galaxies, in contrast, lack a defined structure and may be the result of gravitational interactions or ongoing mergers. This classification system helps astronomers understand the formation histories, stellar populations, and overall evolution of different galactic structures within the universe.
