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 ...

August evenings in the Northern Hemisphere are prime for seeking out globular star clusters. Among the brightest and best for northerners is the Hercules Cluster (M13), which British astronomer Thomas ...

Globular clusters are like astronomical coelacanths — mysterious living fossils. These densely packed collections of ancient stars may hold the ultimate secrets to the formation of galaxies. When you ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

Globular clusters are among the most enigmatic objects in the Universe. They are systems of about 100,000 stars packed into regions of the order of just 10 parsecs (a few tens of light years) in ...
