Astronomers have discovered a "cosmic giant", an accumulation of galaxies whose mbad is a billion times larger than the sun and constitutes "only" 2.3 billion dolphins. years after the Big Bang, Thanks to the European telescope in Chile
"It was a real surprise to see the existence of such an evolved structure in a relatively young universe", has said Olga Cucciati, of the National Institute of Astrophysics of Bologna (Italy), who directs the team responsible for the discovery
It would act of the most extensive structure and the more mbadive ever discovered in the primitive universe. The mbad of this supercluster is "estimated at over a thousand billion times that of the sun." This colossal mbad is similar to that of the largest structures of the contemporary universe, according to the European Southern Observatory (ESO).
Called Hyperion, this cosmic giant was discovered in the constellation Sextant, near the celestial equator, thanks to the very large ESO telescope installed in Atacama, Chile.
Although its dimensions are comparable to those of current superclusters, the structure is very different.
According to the researchers, Hyperion is endowed with a complex structure, composed of at least seven high density regions interconnected by filaments of galaxies. On the other hand, "super-clusters located very close to the Earth (and therefore older, ed) are characterized by a more concentrated mbad distribution and a more structured architecture", explained Brian Lemaux, astronomer at the University from California.
] A difference that could be explained by the prolonged effects of gravity: unlike Hyperion, the superclusters observed in the near universe, more than 13,000 million years after the Big Bang, put several billions of dollars. additional years to condense.
According to astronomers, the dimensions of Hyperion in a universe so early suggest that it will evolve in the same way.
