Scientists use several ideologies/schemes to classify types of galaxies depending on their morphologies. The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.
