Globular Cluster Messier 14 tagged posts

Using the Hubble Space Telescope (HST), astronomers have observed the globular cluster Messier 14 and its peculiar multiple stellar populations. Results of the observational campaign, published January 7 on arXiv.org, deliver important insight into the nature of this cluster.

Globular clusters (GCs) are collections of tightly bound stars orbiting galaxies. Astronomers perceive them as natural laboratories enabling studies on the evolution of stars and galaxies. In particular, globular clusters could help researchers better understand the formation history and evolution of early type galaxies, as the origin of GCs seems to be closely linked to periods of intense star formation.
