WebThe smallest elliptical galaxies (called "dwarf ellipticals") are probably the most common type of galaxy in the nearby universe. In contrast to spirals, the stars in ellipticals do not revolve around the center in an organized way. The stars move on randomly oriented orbits within the galaxy like a swarm of bees.

WebA major discovery made by Shapley using RR Lyrae stars and globular clusters established That the spiral nebulae are actually galaxies outside the milky way. That the spiral arms are regions of star formation. The size of the galaxy and the sun's position in it. That globular clusters lie outside the milky way at large distances. Dwarf ellipticals may be primordial objects. Within the currently favoured cosmological Lambda-CDM model, small objects (consisting of dark matter and gas) were the first to form. Because of their mutual gravitational attraction, some of these will coalesce and merge, forming more massive objects. Further mergers lead to ever more massive objects. The process of coalescence could lead to the present-day galaxies, and has been called "hierarchical merging". If this hypot…
