UK-led study reveals hidden massive star clusters deep inside nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters, described as "ring factories," embedded within nearby galaxies. A complementary analysis of roughly 18,000 star‑forming regions showed that the energetic activity of young stars plays a decisive role in shaping galaxy evolution.
