A bright and spotted galaxy, located on the left, seems attractive, but it is far from the most intriguing object captured by the Hubble Space Telescope. At the top of the visible light from distant galaxies, smeared and twisted in intricate shapes. This is a pointer to the presence of large-scale galactic clusters, bending light from galaxies located behind it.
The cluster was called SDSSJ0150 + 2725. It is 3 billion light-years distant from us and was first recorded by the Sloan Digital Celestial Survey (SDSS). A 2.5-meter telescope was used, which allowed not only to track millions of objects, but also to create detailed 3D maps of the Universe. This cluster belongs to the group with powerful lens properties. The analysis showed that the rate of star formation in such galaxies is low, which corresponds to models suggesting that most stars in similar galactic types appear early. Bright clusters of galaxies emit powerful radio signals belonging to active galactic nuclei. That is, their activity is formed by cold gas located inside host galaxies.
