An imaginary view of a winter night on a planet orbiting a star in the core of a globular cluster. Illustrations created with Stellarium; background image of M4 cluster by the Hubble Space ...

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 ...

As I sat down to write this story, I quickly realized that my problem wasn’t with where to begin, but where to end. If you’re new to the hobby, you may think all globular clusters look the same. Not ...

There is little I love more than gazing at a glittering globular cluster through a big, juicy Dob. The larger the mirror, the better! Each cluster looks a little different, and resolving individual ...

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 — ...

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 ...

Using the Hubble Space Telescope (HST), astronomers have observed a globular cluster known as NGC 1754 as part of a systematic study of the most massive and compact clusters in the Large Magellanic ...

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 ...

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.
