Star clusters are large gravitationally bound groups of stars that are one of the best tools astronomers have to study stellar evolution.

Consider this stellar cluster a modest piece of celestial jewelry. Star clusters are any collection of stars that are gravitationally bound to one another, but this particular set is on the ...

The James Webb Space Telescope captured this image of a galaxy cluster (SMACS 0723). The five zoomed in galaxies are so far away that we observe them as they were when the universe was between one ...

No Gargantua dwells at the heart of stellar cluster NGC 6397. Instead, a few dozen smaller black holes seem to be swarming around in there, throwing their considerable masses around.

Seven strangely-behaving stars in the Milky Way's Omega Centauri cluster may be under the influence of an extremely rare type of black hole, new research suggests.
