Fresh insights into star clusters advance our understanding of galaxy and planet formation.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying ...

Warm mid-August summer nights offer prime conditions for spotting three magnificent star clusters visible to northern-hemisphere skywatchers in the coming months. Star clusters are gravitationally ...

An international team of astronomers reported evidence for the formation of mysterious “super star clusters” Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C. These ...

A trio of massive, young star clusters found embedded in a star cloud may shed light on the formation of super-star clusters and globular clusters. The discovery, made with images taken with the ...

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to ...

In the constellation Taurus, there is a cluster of a few hundred stars known as the Hyades. The cluster is just 150 light-years away, and it could be harboring a stellar-mass black hole. The idea of ...

How would you like to see about a million stars, all crammed together in a tight ball in our Rochester night sky? Well you can do just that. The Great Hercules star cluster is one of the true ...
