An ancient Titan structure from the early universe has been discovered by an international team of astronomers who said Wednesday it was surprising to find such an enormous mass from so long ago.

This galaxy proto-supercluster, nicknamed Hyperion, is so ancient that the Bing Bang predates it by just 2 billion years, which is nothing in space terms.

In a statement, researchers said it is the largest and most massive structure found at such a remote time and distance.

"This is the first time that such a large structure has been identified at such a high redshift, just over 2 billion years after the Big Bang," said Olga Cucciati of Istituto Nazionale di Astrofisica Bologna, who headed up the study. "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. It was a surprise to see something this evolved when the Universe was relatively young."

Space.com noted that redshifts are used as a way of measuring how much of an object's light has been stretched out as it moves away from earth, which basically means redshifts are used to evaluate exactly how long ago the light has left its source.

Less redshift shown by light means it left its source later in the universe's history while a higher redshift means an object is much older— as is the case with Hyperion.

Last month a paper detailing the study was published in the journal Astronomy & Astrophysics.

It highlighted how the international team of researchers analyzed data from the VIMOS instrument on ESO's Very Large Telescope in Paranal, Chile.

The scientists expect that the giant proto-supercluster could evolve into something similar to the massive superclusters making up the Sloan Great Wall or the Virgo Supercluster that contains our own galaxy, the Milky Way.

"Understanding Hyperion and how it compares to similar recent structures can give insights into how the Universe developed in the past and will evolve into the future, and allows us the opportunity to challenge some models of supercluster formation," Cucciati said. "Unearthing this cosmic titan helps uncover the history of these large-scale structures."
