A bright glow of a vortex spiral located in the lower left corner immediately catches the eye. However, this galaxy is far from the most interesting sight - behind it lies the galactic cluster.
Galaxies are not distributed randomly. They are grouped by gravity and form groups and clusters. The Milky Way is a member of the Local Group, a protruding part of the Virgo Cluster, which is also only part of the Laniakeya Supercluster (holds 100,000 galaxies).
The galactic cluster observed here is called SDSS J0333 + 0651. Such formations help scientists better explore the early universe. SDSS J0333 + 0651 displayed as part of the study of star formation in distant galaxies. Usually star sections are not very large and cover up to several hundred light years. Therefore, it is difficult for telescopes to resolve them at a great distance. Even the Hubble Space Telescope can not cope with too distant areas of stellar birth. That is why a space trick is used: galactic clusters are found, whose gravitational influence is so huge that they distort the space-time around them. This distortion is triggered as a lens that increases the light of galaxies located far behind the cluster.
