Galaxy Classification

Galaxy classification is a system used by astronomers to organize galaxies based on their shape and appearance. The main types are elliptical (rounded, smooth shapes), spiral (flat with arms that twist outward), and irregular (lacking a clear shape). Elliptical galaxies are like stretched balls, spirals resemble pinwheels, and irregulars are chaotic. This classification helps scientists understand a galaxy’s structure and evolution, aiding in studying the universe’s history and how galaxies grow and change over time.
