Galaxy morphology refers to the classification and study of the shapes and structures of galaxies. Astronomers typically categorize galaxies into three main types: spiral, elliptical, and irregular. Spiral galaxies, like the Milky Way, have distinct arms winding outward from a central bulge, while elliptical galaxies appear more rounded and smooth. Irregular galaxies lack a defined shape and often result from gravitational interactions. The study of galaxy morphology helps scientists understand the formation and evolution of galaxies over time. By examining their structures, researchers can gain insights into the processes that lead to star formation, the influence of dark matter, and the dynamics of galaxy interactions in the universe.
