WebA spiral galaxy consists of a disk embedded in a spheroidal halo. The galaxy rotates around an axis through the centre, parallel to the GNP ↔ GSP axis in the image. The spheroidal halo consists mostly of Dark Matter (DM), and the DM makes up ∼ 90 % of the mass of the Milky Way. Dynamically, it is the DM, that, ehrm, matters. The earliest stage in the evolution of galaxies is their formation. When a galaxy forms, it has a disk shape and is called a spiral galaxy due to spiral-like "arm" structures located on the disk. There are different theories on how these disk-like distributions of stars develop from a cloud of matter: however, at present, none of them exactly predicts the results of observation. Olin Eggen, Donald Lynden-Bell, and Allan Sandage in 1962, proposed a theory that disk galaxies f… neon green snowboards
