"Clusters rich in red supergiants are very rare and tend to be very far away, but they play a crucial role in understanding key aspects in the evolution of massive stars." When you purchase through ...

As winter's brilliant stars slip toward the western horizon and the constellations of spring climb higher, Northern Hemisphere observers discover a quieter but richly rewarding sky. Spring is ...

Astronomers have discovered the faintest star cluster known, a "ridiculously dim" tiny glob of stars on the outskirts of our Milky Way. The globular cluster is so faint, it is pushing the boundaries ...

In a world increasingly illuminated by artificial light, truly dark skies have become a rare treasure. According to ...

European astronomers, including a scientist from Cardiff University, have discovered the largest known star cluster in the Milky Way. The super star cluster known as ‘Westerlund 1’ is made up of ...

Just when astronomers thought they might have dug up the last of our galaxy’s “fossils,” they’ve discovered a new one in the galactic equivalent of our own backyard. Called globular clusters, these ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide ...

Here’s a hand-wavy attempt: a galaxy is a collection of stars, gas, dust and dark matter all held together by mutual gravity. At the lower end of the scale, some very small galaxies could be ...

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only ...

A new study puts Ursa Major III, a ghostly satellite of our Milky Way, under the microscope. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A ...
