Astronomers Have Found a Massive Galaxy Proto-Supercluster Lurking in The Early Universe

"This is the first time that such a large structure has been identified at such a high redshift, just over two billion years after the Big Bang", Cucciati explained in the discovery paper. At the time, researchers stated that it would likely become part of the most massive structure in our universe.

It has a mass one million billion times greater than the sun and is so distant that it is viewed from earth as it looked billions of years ago. The Titan was one of the 12 children of the god of Earth Gaia and the god of the sky Uranus.

"Thanks to theory, we can infer some sort of evolution of the early universe ... and we have models that we infer how the evolution of the universe started", said Olga Cucciati of the Istituto Nazionale di Astrofisica (INAF) in Bologna, Italy, who is also the lead author of the study published on Wednesday in the Journal Astronomy & Astrophysics.

'Normally these kinds of structures are known at lower redshifts, which means when the Universe has had much more time to evolve and construct such huge things.

What we see in the visible universe is only five per cent of what is out there.

In April 2018, an early cluster of galaxies (a proto-cluster) was discovered in the same region by a team of researchers including Canadians.

The VIMOS, an instrument that measures objects at a distance of billions of light years away, in practice allows experts to see what the early universe was like in the distant cosmic past.

An global team of astronomers using the European Southern Observatory's Very Large Telescope has uncovered the largest and most massive structure ever found in the early universe.

Given its size so early in the history of the Universe, Hyperion is expected to evolve into something similar to the huge structures in the local Universe such as the superclusters making up the Sloan Great Wall or the Virgo Supercluster that contains our Milky Way Galaxy.

"Superclusters closer to Earth tend to a much more concentrated distribution of mass with clear structural features", said Dr. Brian Lemaux, an astronomer at the University of California, Davis.

'But in Hyperion, the mass is distributed much more uniformly in a series of connected blobs, populated by loose associations of galaxies'.

The difference, the team hypothesise, is that superclusters closer to us have had more time to, well, pull themselves together, so to speak - to more tightly gravitationally bind their galaxies into discrete clumps. This galaxy proto-supercluster - which they nickname Hyperion - was unveiled by new measurements and a complex examination of archive data.

"Unearthing this cosmic titan helps uncover the history of these large-scale structures".
