Gigantic discovery star can compel us to review the whole history of the universe

To understand the patterns that shaped the galaxies, it is necessary to study stars. By studying them, astronomers and scientists are able to analyze their masses, births and deaths to better understand the history of the universe.

The Southern European Observatory has just announced that astronomers have discovered that both galaxies of the primordial universe and a nearby galaxy contain a proportion of massive stars much larger than they found in galaxies until then. "We found about 30% more stars with masses larger than thirty times the sun, and 70% more stars with more than 60 solar masses. Our results challenge the previous idea that predicted the limit of 150 solar masses for the largest mass of birth and they even suggest that stars can have initial masses of 300 solar masses! "says Fabian Schneider of Oxford University (England). That information changes everything. "Our discoveries make us question our understanding of cosmic history. Astronomers who build models of the universe must now go back to the beginning, and use more sophisticated models, "complements Rob Adisa, co-author of the study. [ESO, Outerplaces]
