ABOUT THIS IMAGE:

This illustration shows the comparative sizes of our Milky Way Galaxy and an ultracompact galaxy, which existed in the early universe. Although the compact galaxy is only a fraction of the size of our Milky Way, it contains the same number of stars. The small, dense galaxy could fit inside the central hub of our Milky Way.
