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 ...

A team of Canadian astronomers, including experts from the Dunlap Institute for Astronomy & Astrophysics in the University of Toronto's Faculty of Arts & Science, have used the James Webb Telescope ...

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 ...

Globular clusters, which have been forming over the last billion years, have been found to exist around the giant galaxy at the center of the Perseus cluster. Globular clusters may contain hundreds of ...

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 ...

Modern astronomy holds that all major galaxies (with the Milky Way as no exception) are the accumulation of numerous small mergers. Thus, it should be expected that some of the globular clusters that ...

A: Globular clusters are compact, spherical collections of stars usually found in the halo of galaxies. The Milky Way is home to 150 known globular clusters. These clusters are much older and more ...

Radcliffe Wave origin identified in new preprint: Pulkovo Observatory astronomers Bobylev and Bajkova propose globular cluster NGC 4372 plunged through the Milky Way disk 55.5 million years ago, ...

Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting ...
