The stars in M15 and other globular clusters are estimated to be about 12 billion years old. They were among the first generations of stars to form in the Milky Way. Our Sun, by comparison, is a ...

This paper reports the discovery of a high-velocity star J07 ejected from globular cluster M15 approximately 21 million years ago, providing strong evidence for the presence of an IMBH constrained ...

For Northern Hemisphere observers, M15 ranks as autumn’s showpiece globular cluster. From a dark site, sharp-eyed observers can spot magnitude 6.3 M15 with their naked eyes.

New research, funded by NASA and the University of Tokyo, has shown astronomers may not yet have uncovered the mystery at the heart of one of the Galaxy's oldest star systems, the globular cluster ...

While most of the Milky Way’s globular clusters are found in the summer sky hovering around the galactic center, a few stragglers reside off the beaten path. One such cluster is M15, located ...

In a mesmerizing display of celestial beauty, a stunning photo from NASA's Hubble Space Telescope shows the captivating globular star cluster known as Messier 15 (M15). This ancient cluster ...

Astronomers have studied the globular cluster 47 Tucanae extensively, but still have many questions. It may have an ...

In a surprising discovery, astronomers have found a globular star cluster in the Andromeda galaxy that contains a record-breaking low amount of metals. The stars in the cluster, called RBC EXT8, have ...
