Supercluster SPT2349? 56 was found in the submillimeter band by the South Pole Telescope. Astronomer Matthew Ashby from the Harvard Smithsonian Center for Astrophysics (CfA) was one of the staff member who performed follow-up observations with the Gemini Observatory, the Hubble Space telescope and the Spitzer Space Telescope in order to carry out deep observations at optical and infrared wavelengths.

SPT2349? 56 hosts numerous galaxies, consisting of over thirty submillimeter-bright galaxies and dozens of other luminescent and/or spectroscopically validated star-forming galaxies. Even though this is a cluster of galaxies from the early Universe, galaxy mergers and active star development is happening at an unbelievable rate, producing over ten thousand stars annually. The astronomers said among its brightest sources appears to be the merger of over twenty galaxies.
A newly discovered supercluster of galaxies is so distant that astronomers state its light has been taking a trip for over twelve billion years to reach telescopes in the world. This cluster, called SPT2349? 56 is massive, and so old that it is really categorized as a proto-cluster of galaxies, implying it may be among the earliest large clusters of galaxies in our Universe. It is likewise one of the most actively star-forming proto-clusters known.

Among the goals of the observations was to try to acquire the excellent mass of the system; however the team was unsuccessful. They said not understanding the outstanding mass of the system made it difficult, for example, to understand whether the substantial burst of stars they observed was the result of an amazing efficiency or just developed because the system was so very large.
A typical supercluster contains all the galaxy groups and galaxy clusters that appear to be associated with one another through mutual gravitational destination, and includes about a quadrillion solar masses. Astronomers have approximated that there are 130 superclusters situated within 1.3 billion light-years of the Milky Way. Another supercluster from the early Universe that was identified by the South Pole Telescope in 2010, weighs in at around 800 trillion Suns, and holds hundreds of galaxies.
The astronomers found that the star formation rate in this primitive cluster compares likewise to the star development rate determined in close-by, routine galaxies, therefore they conclude that the star development procedures at work in this early Universe are similar to those that came later on, in the regional universe. They discovered that this cluster does, however, reveal a deficit of molecular gas, recommending that the activity is nearing completion of this turbulent stage as the raw product for stars is being dissipated.
The astronomers said they anticipate that the core galaxies of this supercluster will rapidly merge into among the brightest galaxy clusters, which their observations provide a direct view of the early development systems of this class of object.

Astronomers have actually finished deep optical and infrared observations of the complex and concluded that the star formation procedures at work, although remarkably active, usually seem to follow the exact same processes seen in our galaxy.

56 is enormous, and so old that it is actually classified as a proto-cluster of galaxies, indicating it might be one of the earliest big clusters of galaxies in our Universe. 56 hosts hundreds of galaxies, including over thirty submillimeter-bright galaxies and lots of other luminous and/or spectroscopically validated star-forming galaxies. Even though this is a cluster of galaxies from the early Universe, galaxy mergers and active star formation is taking place at an incredible rate, producing over ten thousand stars per year.
