Astronomers now believe that disk galaxies likely formed first, then evolved into elliptical galaxies through galaxy mergers. Current models also predict that the majority of mass in galaxies is made up of dark matter , a substance which is not directly observable, and might not interact through any … Meer weergeven The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over … Meer weergeven 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 … Meer weergeven One observation (see above) that must be explained by a successful theory of galaxy evolution is the existence of two different populations of galaxies on the galaxy color-magnitude diagram.
