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. It was invented by John Henry Reynolds and Sir James … Meer weergeven Ellipticals On the left (in the sense that the sequence is usually drawn) lie the ellipticals. Elliptical galaxies have relatively smooth, featureless light distributions and appear as ellipses … Meer weergeven Elliptical and lenticular galaxies are commonly referred to together as "early-type" galaxies, while spirals and irregular galaxies are referred to as "late types".
