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 ...

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 ...

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 ...

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 ...

KISSIMMEE, Fla. — Densely packed groups of stars may make excellent cradles for complex space-traveling life to evolve. Despite studies that claim these environments, known as globular clusters, may ...

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 ...

Searching for ET? Check out one of the Milky Way's 150 or so globular star clusters. That's where you'll find the sort of quiet, well-established stellar neighborhoods that might provide favorable ...

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 ...

The word globule isn’t the most appealing term. Maybe this is why globular clusters don’t get as much press as they deserve. These dense collections of ancient stars numbering in the tens of thousands ...

Michelle Starr is CNET's science editor, and she hopes to get you as enthralled with the wonders of the universe as she is. When she's not daydreaming about flying through space, she's daydreaming ...

This NASA/ESA Hubble Space Telescope image shows the globular cluster Fornax 2 in the dwarf galaxy Fornax. New observations of this cluster and three others in the galaxy show that they are very ...
