Globular clusters (GCs) are spherical collections of tightly gravitationally bound stars. They contain from tens of thousands to millions of stars and investigating them could help us better ...

We have compared the locations of point sources found by the X-ray Multiple Mirror-Newton (XMM-Newton) satellite with the positions of globular clusters that have been identified in optical imaging ...

Discover the unexpected complexities of globular clusters and their role in stellar evolution and age determination. Click to learn more! When the GC is young, you don't expect to see too many ...

Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" ...

Using the Karl G. Jansky Very Large Array (VLA), astronomers have discovered a millisecond pulsar in the globular cluster GLIMPSE-C01 as part of the VLA Low-band Ionosphere and Transient Experiment ...

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 ...

Observations by the Swift gamma-ray-burst (GRB) mission located short GRBs in (or near) elliptical galaxies, that are no longer active in star formation. This suggested that short GRBs are produced ...

Some of the oldest objects in the universe may still have a long way to go, according to a new study using NASA’s Chandra X-ray Observatory. These new results indicate that globular clusters might be ...

The universe is more than a smattering of distant stars—it’s also chock-full of other worlds. But if the universe is so crowded, where is the alien life? While there are many theories addressing this ...

BOSTON, Jan. 6 (UPI) --Astronomers from the Harvard-Smithsonian Center for Astrophysics say globular clusters -- large, dense spheres of stars -- are the galactic regions most likely to harbor ...
