Astronomers found a young galaxy cluster with unexpectedly hot gas, suggesting cosmic structures formed faster than once ...

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe.

Christmas-themed imagery knows no bounds, not even in space. NASA has drawn comparison between a celestial formation and a holiday wreath, referring to the recently spotted star and dust cloud cluster ...

The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion years old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led ...

On the left, an artist’s impression of a globular cluster near its birth, hosting extremely massive stars with powerful stellar winds that enrich the cluster with elements processed at extremely high ...

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 ...
