…mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centers of galaxies. Galaxies are categorised according to their visual characteristics such as elliptical, spiral, or…
