Hubble's classification of galaxies

Web19 mrt. 2024 · Hubble recognized that there are basically two classes of galaxies: disk-shaped galaxies and non-disk-shaped galaxies. Elliptical galaxies are characterized by a well-defined interconnectedness of their physical parameters. Spiral galaxies are generally two-component systems consisting of a bulge and a disk. Web12 jul. 2024 · There are three main classes of galaxies: Irregulars, Ellipticals, and Spirals. Irregular galaxies, as their name suggests, do not fit into the "normal" classification scheme. So, how do we distinguish between elliptical and spiral galaxies? Brighness profile

The Hubble sequence is a morphological classification scheme for galaxies published by Edwin Hubble in 1926. It is often colloquially known as the Hubble tuning-fork diagram because the shape in which it is traditionally represented resembles a tuning fork.
