The Hubble Space Telescope is 30 years old, and in its long career it’s photographed many of the 150 “globular clusters” that surround the Milky Way galaxy—like its latest photo, this week, of NGC ...

A strange, newly measured clump of stars orbiting the nearby Andromeda galaxy has the lowest level of heavy chemical elements ever seen in one of these mysterious star clusters. Named RBC EXT8, this ...

Globular clusters maintain their structural integrity primarily due to the angular momentum of their constituent stars, preventing gravitational collapse towards the cluster's center of mass. While ...

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 ...

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 ...

This article was originally published on The Conversation. Read the original article. One of the most fundamental questions in modern astrophysics is how galaxies first formed. The Milky Way, the ...

In a few billion years, there may be no stars left in the Palomar 5 cluster. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A cluster composed ...

'Stellar archaeology' reveals a star stream composed of the remnants of an ancient globular cluster that was torn apart by the Milky Way's gravity 2 billion years ago Pasadena, CA--A team 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 ...

For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter. Using ultra-detailed simulations, researchers recreated their origins and ...

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 ...

Comparison of traditional velocity dispersion and pulsar timing methods (left) versus the HiVel ejection from globular clusters method (right) in the search for IMBHs. Recently, Associate Professor ...
