Scientists have discovered a stellar stream consisting of the remnants of the ancient globular clusters are broken by the gravity of the milky Way two billion years ago. The study is published in the journal Nature.
A globular cluster is a sphere, consisting of hundreds of thousands and even millions of stars, bound by gravity and orbiting around the galactic nucleus. Our Galaxy has about 150 globular clusters. But the "field of stars", which was recently discovered by astronomers of the international consortium of S5 is very different from the usual and well-studied globular clusters in the milky Way.
