The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...
It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...
Where are the smallest galaxies? A recent study suggests that there may not be as nearly as many of them in the early universe as there should be, which has big implications for the story of how our ...
