The Hubble Space Telescope has captured images of an ancient globular cluster in our galaxy, nicknamed the "Chandelier Cluster," which shows evidence of star formation occurring in two distinct bursts. Globular clusters are dense collections of tens of thousands to millions of stars held together by gravity. Over 150 such clusters exist in the Milky Way, though more may remain hidden by interstellar dust or crowded stellar fields.


Understanding multiple star formation episodes in globular clusters helps astronomers refine models of galactic evolution and stellar population dynamics. These ancient structures serve as natural laboratories for studying stellar physics and the early history of our galaxy.


The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be others still undiscovered, hidden from view by dust or densely packed fields of stars.
