The Hubble Sequence is a morphological classification scheme for galaxies, introduced by Edwin Hubble in the early 20th century. It categorizes galaxies based on their shapes and structures into three main types: elliptical, spiral, and irregular. This sequence helps in understanding the evolutionary pathways and relationships between different galaxy types, revealing how their morphology relates to factors like environment and dynamics.
congrats on reading the definition of Hubble Sequence. now let's actually learn it.
