To understand how galaxies interact in today ’s universe , we necessitate to look at the distant past times , and now astronomers have observed an ancient galax bunch just about to form .
Using scope in Arizona and Hawaii , an international squad of physicists observe a “ proto - cluster ” forming about 1.7 billion years after the Big Bang with the mass of a quadrillion Suns . The squad notice 953 Galax urceolata that seem to be clumping up in the same area of the sky , and the astronomers were able-bodied to confirm that at least 65 of them are really come together .
“ Many of the dim galaxies in this patch Trygve Halvden Lie at the same space , ” said Dr. Arjun Dey , lead author of the study , in astatement .
“ They are clumped together due to sombreness and the grounds suggest that the clustering is in the process of forming . ”
Galax urceolata in the universe are not parcel out randomly , but their location reckon importantly on the gravity of the objects around them . There are coltsfoot all alone while others , like the Milky Way , are in groups . The denser groups are the clusters , with some of them have a combined people of a million billion ( quadrillion ) Suns .
“ The protocluster will very belike grow into a monumental bunch of galaxies like the Coma bunch , which count more than a quadrillion sun , ” said Dr. Kyoung - Soo Lee , the discoverer of the protocluster and co - source of the study , which is published inThe Astrophysical Journal .
The shaping and infancy of these cluster are not completely clear yet , but the find of protoclusters can help understand how these complex giant bodily structure follow to organize . infer how cluster configuration provides clues to the evolution of the population as a whole . The size and number of galaxy clusters depend on the rate of expansion of the universe as well as the matter content of the universe .
While the uncovering of such a removed and massive bunch is fascinating , to truly understand cluster like this we need to take note many more . With this finish in intellect , the team is now observe big areas of the sky in the hope of find out many more of these protoclusters .
