Galaxy Classification - JSON

Galaxy classification is a morphological classification system proposed by Edwin Hubble in 1926, which categorizes galaxies into five main types based on their visual appearance: elliptical, lenticular, spiral, barred spiral, and irregular galaxies. Known as the 'Hubble Tuning Fork,' this classification remains widely used as a foundation in astronomy nearly a century later. It was later extended by Gérard de Vaucouleurs and continues to play an important role in modern galactic research.
