Globular clusters are gravitationally bound, dense star collections containing tens of thousands to millions of stars, often located in galactic halos. Omega Centauri, the largest known globular ...

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 ...

Late June is the best time in the year to observe the brightest and best globular clusters in the northern sky. Globular clusters are among the oldest objects in the universe, perhaps older than the ...

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 often described as ancient, tightly bound fossils of the early Milky Way. It has been believed that ...

Astronomy is a science of observation. Unlike biologists or chemists, astronomers can't manipulate the objects they study. And against a night sky whose stellar inhabitants all appear identical, ...

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 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 span ...

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 ...

New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed ...

'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 ...

Hidden Holes: Omega Centauri is a globular cluster hosting around 10 million stars and is visible from Earth's southern hemisphere with the naked eye. The cluster has been studied for 2,000 years and ...
