galactic morphology

Galactic morphology refers to the classification of galaxies based on their visual appearance and structural features. The main types are spiral galaxies, with rotating arms and a bright center; elliptical galaxies, which are more rounded or elongated with a smooth appearance; and irregular galaxies, which lack a distinct shape. This classification helps astronomers understand the galaxy's formation, stellar content, and evolution. The shape and structure are influenced by factors like star formation, galaxy interactions, and cosmic environment. Overall, galactic morphology provides insight into a galaxy’s history and dynamics within the universe.
