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.
