Astronomers have discovered a galaxy cluster burning five times hotter than theoretical models predicted, just 1.4 billion ...

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

How do stars form and evolve inside globular clusters? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers conducted a ...

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that ...

Astronomers have found something the universe wasn’t supposed to have: a galaxy cluster blazing with hot gas just 1.4 billion years after the Big Bang, far earlier and hotter than theory predicts. The ...

Researchers at the University of British Columbia and Dalhousie University have found a young galaxy cluster that appears far ...

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 ...

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

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 ...
