The data from the world’s leading telescope helped scientists discover to GOODS-N-774 – a huge bright ball of constantly being born stars, who was the “nucleus” of the future of a massive galaxy, writes Surfingbird.ru. Until now, astronomers have not been able to detect the earliest stages of galaxy formation in the early universe. Theorists talked about that massive elliptical galaxies have to start over with an incredibly bright and a spherical nucleus, active generation of stars which started closer to the center, and then spread to the outer area, sparking protogalaxies like a giant New Year’s ball and starting the process of galactic evolution.

GOODS-N-774 is 11 billion light years from us. This means that in the form in which we now see it, it was in the days of the early universe – after “only” three billion years after the Big Bang.

The size of it is 16.5 times smaller than our Galaxy, but has already twice more stars and consequently twice the mass. Also around the GOODS-N-774 are active star formation processes – if somewhere in this protogalaxy already have planets, their night sky is literally strewn with bright astronomical phenomena, the researchers note.

The discovery is important that opens a new chapter in the study period of youth of our universe.

“This process of formation of the galactic nucleus is a phenomenon very early universe. Now we do not observe galaxies that can develop in this way. At that time in the universe was something that helped galaxies formed in this way, but now it is impossible. We assume that the universe before could produce brighter objects because it was generally brighter in the aftermath of the Big Bang. Now she no longer has such a bright, “- says Eric Nelson (Erica Nelson), Yale University

These objects are very difficult to register because they are light, how bright he was, often hidden behind clouds of interstellar gas and dust, which is typical of active star formation regions .

To discover and explore the GOODS-N-774, the researchers combined data from space-based telescope “Hubble”, “Spitzer”, “Herschel”, as well as ground-based observatory “Keck” in Hawaii.
