In this episode, Astronomy magazine Editor Dave Eicher invites you to head out and observe M4, the wonderful globular cluster in the constellation Scorpius the Scorpion. You can use the Scorpion's ...

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

A previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular ...

A globular cluster is a densely packed collection of ancient stars that typically appear spherical in shape. Most of them are estimated to be about 10 billion years old and are home to some of the ...

Globular clusters will soon be studied with another tool as well, as one such cluster called Messier 92 is the target of an early science program using the James Webb Space Telescope.

“Hubble revolutionized the study of globular clusters,” ESA officials have previously written. The space telescope’s orbital altitude of about 326 miles above Earth’s surface gives it an ...

An international team of astronomers have created the most sensitive radio image ever of a globular cluster. The team imaged 47 Tucanae, an ancient ball of tightly-packed stars and […] Search for: ...

However, unlike most globular clusters, its stars are relatively young. This Hubble image shows the star cluster NGC 1850, located about 160,000 light-years away.

But it’s not. M3 is what’s called a globular cluster. Scientists believe it’s 11 to 13 billion years old, and it is home to half a million stars.

A new Hubble Space Telescope image shows a partial view of the globular star cluster Messier 55 about 20,000 light-years away. M55 was first spotted in 1752.

The globular star cluster M92, shown here in an image from the Hubble Space Telescope, appears to be about 13.8 billion years old — the same age as the universe. ESA/Hubble, NASA, Gilles Chapdelaine ...

ESO 280-SC06, a faint and metal-poor globular cluster about 67,000 light years away, has lost 95–98% of its original mass, far exceeding typical mass loss in similar clusters.
