Description
Galaxies are huge clusters of stars held together by mutual attraction, so as to constitute a system self-gravitating. The discovery of clusters of galaxies is very important from the cosmological point of view, because it helps you learn more about the value of the density of matter in the cosmos. From this value we can determine the curvature of the Universe and its destiny.
