New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed ...

Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows ...

A study published today in Astronomy & Astrophysics marks a significant milestone in our understanding of the formation and dynamical evolution of multiple stellar populations in globular clusters ...

As we carefully map the stars of our Milky Way, we're able to identify features that tell us of its history. These include local details, such as the stars that have passed through an area from which ...

For generations, astronomers have pondered the origins of globular clusters, which are among the universe’s oldest and densest star systems. Research led by the University of Surrey and published in ...

Looking out into the Milky Way, it's possible to see all sorts of strange cosmic structures — tentacle-like spiraling arms of stars in the outer regions of the galaxy, dark clouds of gas and dust that ...

Publications of the Astronomical Society of the Pacific, Vol. 119, No. 860 (October 2007), pp. 1085-1092 (8 pages) ABSTRACT This paper is the third in a series of papers on M81 globular clusters. In ...

Globular clusters are compact groups of up to a million or so stars held together by their mutual gravitational attraction, with a nearly spherical distribution and high density in the center. Our own ...
