Galactic morphology is the study of the physical structure and classification of galaxies, based on their visual characteristics and underlying composition. Astronomers utilize classification systems such as the Hubble sequence to categorize galaxies by their defining features, including their spiral arms, central bulges, and disk structures. Beyond these broad categories, the Hubble classification also takes into account more intricate structural elements like stellar halos, warps, tidal tails, and the presence of shells, which provide additional insights into a galaxy’s formation and evolutionary history. This classification system helps scientists understand not only the diversity of galaxy shapes but also the dynamic processes shaping their development across cosmic time.
