+The Hubble Sequence is a morphological [classification](/wiki/classification) scheme for [galaxies](/wiki/galaxy). Introduced by [Edwin Hubble](/wiki/Edwin_Hubble), it organizes them into distinct types based on their visual appearance, often depicted as a "tuning fork" diagram. This framework helps astronomers understand the diverse forms and evolutionary paths of stellar systems.
