Astronomers have performed abundance measurements for 11 globular clusters in the galaxies NGC 147, NGC 6822, and Messier 33. The new study, presented January 9 in a paper published on arXiv.org, could improve our knowledge ...
Astronomers expect that the first galaxies, those that formed just a few hundred million years after the Big Bang, would share many similarities with some of the dwarf galaxies we see in the nearby universe today. These early ...
