Astronomers discover hundreds of black holes hiding in the star system

Astronomers at University of Surrey found evidence of black holes in the globular cluster NGC 6101. Using computer simulation they showed that the clusters strange appearance can be explained if stellar mass black holes are still present in the cluster. Until now it was assumed that black holes in globular clusters usually are ejected after their creation. Sep 8, 2016

Astronomers make rare discovery that could help explain Milky Way formation

The Terzan 5 cluster could shed light on how the Milky Way was formed after an Italian-led team of astronomers found it contained two very different types of stars; some very young and some very old. The 7 billion year age gap between the two different types of stars suggests that star formation in Terzan 5 was not continuous but happened in two very distinct bursts. Sep 7, 2016
