Globular star clusters are extraordinary in almost every way. They’re densely packed, holding a million stars in a ball only about 100 light-years across on average. They’re old, dating back almost to ...

A globular cluster is a spherical collection of stars. Globular clusters are very tightly bound by gravity, giving them their spherical shapes and high concentrations of stars toward their centers.

Astronomers from the University of Texas at Austin and Germany’s Max Planck Institute for Extraterrestrial Physics (MPE) recently found a surprise when studying some of the oldest star clusters in our ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

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 ...

Hubble recently captured a dazzling image of the heart of globular cluster Terzan 9, a bright ball of stars 23,000 light years away. Globular clusters are tightly packed groups of tens of thousands — ...

The word globule isn’t the most appealing term. Maybe this is why globular clusters don’t get as much press as they deserve. These dense collections of ancient stars numbering in the tens of thousands ...

This week’s image from the Hubble Space Telescope shows a stunning field of stars called a globular cluster. Taken with Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys instruments, the ...

This NASA/ESA Hubble Space Telescope image shows the globular cluster Fornax 2 in the dwarf galaxy Fornax. New observations of this cluster and three others in the galaxy show that they are very ...
