By noticing the exceptionally bizarre orbital behavior of a specific star in the cluster, the researchers were able to conclude that a black hole is lurking in the core of NGC 3201, located some ...

Globular star clusters are huge balls of thousands of stars that orbit most galaxies. They are among the oldest known stellar systems in the Universe and have survived through almost the entire ...

The strongest pulsar candidate turned out to be the source in GLIMPSE-C01—a dense and massive intermediate-age GC located about 10,760 light years away from the Earth.

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 ...

Astronomers have discovered a new class of 'dark' globular star clusters around the giant galaxy Centaurus A. These mysterious objects look similar to normal clusters, but contain much more mass ...

This paper reports the discovery of a high-velocity star J07 ejected from globular cluster M15 approximately 21 million years ago, providing strong evidence for the presence of an IMBH constrained ...

Astronomers spotted the most distant globular clusters ever discovered, and they’re in a 9-billion-year-old galaxy pictured in Webb's First Deep Field.

Astronomers have performed photometric observations of a young globular cluster known as NGC 1851. The new observational campaign provides more insights into the variable star population of this ...

Using the Hubble Space Telescope, astronomers have made the first direct observation of star clusters colliding and merging at the hearts of dwarf galaxies. The discovery could help scientists ...

A new Hubble Space Telescope image shows a partial view of the globular star cluster Messier 55 about 20,000 light-years away. M55 was first spotted in 1752.
