“Most of the Milky Way satellites have very ancient star populations. They stopped forming stars about 10 billion years ago,” said Marco Arias, the lead author of the study, in the same release.

The Milky Way, however, is much larger than would be expected based on the size of our Local Sheet, despite not being an uncommonly large galaxy on a universal scale.

The Milky Way contains between 100 billion and 400 billion stars, but the exact number is difficult to determine due to the galaxy's vast size and the presence of dust that obscures our view.
