NASA Hubble discovered the largest of all the currently known population of globular star clusters, containing about 160,000 stars orbiting around the center of Abell 1689 galaxy cluster in the constellation Virgo. An international team of researchers used the camera Advanced Camera for Surveys telescope Hubble for a detailed study detected a population that is characterized by an unprecedented density. Scientists suggest that such a compact location of stars in the star cluster may indicate the presence of a huge amount of dark matter. According to Karla Alamo-Martinez of the Center for Radio Astronomy and Astrophysics, functioning at the National Autonomous University of Mexico, in the course of the research he and his colleagues were able to identify the relationship between the globular clusters and dark matter, that is, as the distance from the center of the galactic star cluster affects amount of dark matter.
