Close," however, is only relative to other clusters of galaxies , since light takes about 50 million years to reach us from A2199. All of the fuzzy objects in the above picture are galaxies , but these galaxies do not contain most of the matter in the cluster. By studying clusters like A2199, astronomers conclude that some form of dark matter dominates the motion of the bright galaxies. ...

Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
