New treasure trove of globular clusters holds clues about galaxy evolution
A survey completed using a combination of ground and space-based telescopes yielded a treasure trove of previously unknown globular clusters—old, dense groups of thousands of stars that all formed at the same time—in the outer regions of the elliptical galaxy Centaurus A. The work presents a significant advance in understanding the architecture and cosmological history of this galaxy and offers new insights into galaxy formation in general and the distribution of dark matter in the universe.
