The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion years old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led ...

Chinese astronomers have conducted observations and analyses of star clusters in the outer halo of the Andromeda Galaxy — the ...

A stunning new image released by NASA on March 19, 2026, reveals Westerlund 2, a cluster of stars glowing in neon pink, ...

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that ...

Take some cosmic dust and gas, add billions and billions of planets and a whole lot of stars to the mix. Spice it all up with ...

Discover how Hubble's latest image reveals Messier 88, a spiral galaxy losing its star-forming fuel on a slow journey through ...

New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed ...

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 ...

Star clusters arise within the densest cores of molecular clouds, where gravity drives the collapse of gas and dust to form stars nearly simultaneously. Their formation is regulated by the complex ...

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 ...
