Astronomy & Astrophysics 101: Globular Cluster
What Is a Globular Cluster? Globular clusters are stable, tightly bound clusters of tens of thousands to millions of stars. They are associated with all…
Globular Clusters are spheroidal groups of thousands to millions of stars bound together by gravity. Because the constituent stars formed at similar times, and the high density of these clusters, scientists have observed these structures to learn more about star formation, gravitational waves, and stellar evolution.

New research led by the University of Warwick reveals that globular clusters could be up to 4 billion years younger than previously thought. Once thought…
Since the limited amount of gas survived from the first bulk star forming process will be quickly expelled within several million years, star clusters have…
This newly released Hubble image shows globular cluster NGC 362. Globular clusters offer some of the most spectacular sights in the night sky. These ornate…
Astronomers from the Harvard-Smithsonian Center for Astrophysics have analyzed the distribution of over eighty thousand globular clusters to infer an active history of galaxy-galaxy interactions….
Using Hubble data, a team of astronomers has for the first time found young populations of stars within globular clusters that have apparently developed courtesy…
Astronomers reach an important milestone in the study of cluster mergers, showing that member galaxies are still gas rich and thus can form stars and…
This newly released Hubble image shows globular cluster NGC 1783, which is about 160,000 light-years from Earth. Shown here in a new image taken with…
Using the Atacama Large Millimeter/submillimeter Array, astronomers have discovered what may be the first known example of a globular cluster about to be born. Globular…
A new study from the Harvard-Smithsonian Center for Astrophysics reveals that globular clusters are often gathered into distinct groupings whose shapes reflect the formation of…
This newly released Hubble image shows a globular cluster of stars known as Palomar 12. Panta rhei is a simplified version of the famous greek…
This newly released Hubble image shows globular cluster NGC 6535. This image captures the stunning NGC 6535, a globular cluster 22,000 light-years away in the…
This newly released Hubble image shows the globular cluster IC 4499. Globular clusters are big balls of old stars that orbit around their host galaxy….
Using the new Integral Field Unit instrument VIRUS-W in conjunction with the 2.7-meter Harlan J. Smith Telescope, astronomers discovered that stars at the centers of…
This newly released Hubble image shows star cluster Messier 15, which is one of the oldest known globular clusters and is located roughly 35,000 light-years…
Using an array of radio telescopes, a team of astrophysicists discovered the first examples of black holes in globular star clusters in our own galaxy….
Using the Hubble Space Telescope, astronomers have uncovered the largest known group of star clusters and have confirmed that such compact groupings can be used…
Using Hubble and the W. M. Keck Observatory’s 10 meter telescope in Hawaii, astrophysicists discovered several star clusters with sizes and masses that were previously…
