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 ...

Massive star clusters may have blasted enough ultraviolet radiation into space to transform the early universe, new research ...

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 ...

Fresh insights into star clusters advance our understanding of galaxy and planet formation.

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 ...

This NASA/ESA Hubble Space Telescope image shows the globular cluster Fornax 2 in the dwarf galaxy Fornax. New observations of this cluster and three others in the galaxy show that they are very ...

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 ...

Fastest cluster emergence: Massive star clusters disperse their birth clouds in about five million years, compared to seven to eight million for smaller clusters. Impact on galaxies: Early ultraviolet ...

Massive star clusters brimming with giant, luminous blue stars are forming in the unraveled wreckage of interacting galaxies. When you purchase through links on our site, we may earn an affiliate ...
