'''Galaxy morphological classification''' is a system used by [[astronomer]]s to divide [[galaxy|galaxies]] into groups based on their visual appearance. There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the [[Hubble sequence]], devised by [[Edwin Hubble]] and later expanded by [[Gérard de Vaucouleurs]] and [[Allan Sandage]]. However, galaxy classification and morphology are now largely done using computational methods and physical morphology.
