A new photo from the Hubble Space Telescope camera (NASA and ESA) shows a landscape with thousands of globular clusters underlying the cluster of galaxies. The survey used information from three separate telescope observation programs. The goal is to study the center of the cluster of Hair of Veronica. It lives at a distance of 320 million light years from us and contains more than 1000 galaxies connected by gravity.
Scientists managed to find more than 22,000 globular clusters. Some of them even formed a bridge in the merger process (for example, NGC 4889 and NGC 4874). Globular cluster is a spherical group of stars, which usually rotates around galaxies as an independent satellite. In the specific case, we are talking about a different type of clusters that are not tied to a separate galaxy, but belong to the galactic Volos Veronica's cluster. Globular clusters revolving around the Milky Way behave like bright spherical and dense star groups. But at a distance of Veronica's Hair Clusters they resemble tiny points of light in the Hubble photo. But here one can still see a characteristic feature of globular clusters - color, because stars usually belong to the same period of formation and one type.
Thus, we managed to identify clusters and eliminate background galaxies by analyzing their color and size. Identified globular clusters will display the distribution of matter and reveal dark matter in the cluster of Hair of Veronica.
