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 ...

Globular clusters, among the oldest bound stellar systems in the Universe, offer a unique laboratory for understanding stellar evolution and dynamics. Traditionally considered simple stellar ...

Globular clusters remain gravitationally bound as they orbit their host galaxy, on a timescale comparable to the lifetime of the low-mass stars they host. They are 10 billion to 13 billion years old — ...

The distance to one of the oldest star clusters has been precisely measured by the NASA Hubble Space Telescope for the first time. This measurement provides a more accurate and independent estimate ...
