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 ...

Globular clusters are giant balls of millions of stars held together by gravity and orbiting in the halo of our Milky Way galaxy. On November 5, 2024, scientists from the National Institute for ...

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 previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular clusters like this one, called ESO 591-12 or Palomar 8, are spherical ...

Globular clusters are tightly packed, symmetrical collections of as many as 10 million stars. These behemoths can reach 300 light-years in diameter. They orbit mostly in the vast stellar halos ...

Two newly discovered globular clusters have been added to the total of just 158 known globular clusters in our Milky Way. They were found in new images from ESO’s VISTA survey telescope as part of the ...

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 ...

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 ...
