Astronomers of European Southern Observatory (ESO, because the acronyms are worth speaking Spanish) they discovered a small, young galaxy, located 12 billion light years from Earth, which turns out to be very similar to the Milky Way.
This find was cataloged with the code name SPT0418-47 and it is estimated that the observations correspond to when this galaxy was 1.4 billion years old, barely 10% of his current age.
The galaxy has a constitution very similar to that of the Milky Way, with a high density of stars located around the center of it., which is challenging current astronomical studies, since Galaxies of this type were not believed to exist in the time period that the observation was obtained.
The researchers recognized that there was no previous record of a galaxy as young with a central bulge of stars as the Milky Way and others have within the observable universe. However, this more than a problem, it seems to be a great and interesting new variable for the ESO researchers.
Likewise, It is surprising that despite its youth, this galaxy has an unusual calm state. This may cause many of the theories of the chaotic universe after the Big Bang and the nature of the origin of astronomical formations such as galaxies to be rethought.
Simona Vegetti, a researcher at the German Max Planck institute, co-author of the study released in Nature, explained that:
“This we have discovered is quite puzzling: despite the fact that it forms stars at a high rate and is the site of highly energetic processes, SPT0418-47 is the best-ordered galactic disk observed to date in the young Universe. This result is quite unexpected and has important implications for how we think galaxies evolve. It may be that the universe was not as chaotic a place as was believed so shortly after the ‘Big Bang’“
