Globular clusters maintain their structural integrity primarily due to the angular momentum of their constituent stars, preventing gravitational collapse towards the cluster's center of mass. While ...

Take some cosmic dust and gas, then add billions and billions of planets and a whole lot of stars to the mix. Spice it all up with a handful of gravity to hold things together, and you get a galaxy.

New Hubble Space Telescope data confirms that "blue straggler" stars maintain their youthful glow by siphoning fuel from binary companions ...

Globular clusters are the fossils of the astronomical world. We know they are very old, having formed shortly after the Big Bang. Furthermore, they must be pretty robust, since many have survived ...

A glittering multitude of stars in the globular cluster Terzan 4 fills this image from the NASA/ESA Hubble Space Telescope. Globular clusters are collections of stars bound together by their mutual ...

NASA’s Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. Globular clusters are spherical concentrations of hundreds of ...

Globular clusters, among the oldest bound stellar systems in the Universe, offer a unique laboratory for understanding stellar evolution and dynamics. Traditionally considered simple stellar ...

A globular cluster glitters with starlight in a new photo from the Hubble Space Telescope. Located 15,000 light-years from Earth, the globular cluster — formally known as Terzan 12 — is nestled deep ...
