WebAlthough the formation of galaxies is not fully understood, astronomers have identified the three key processes involved: primordial collapse: the collapse of individual gas clouds early in the history of the Universe. hierarchical clustering: the formation of large galaxies through the merging of many smaller ones. 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.
