UK-led study reveals hidden massive star clusters deep within nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters embedded deep inside nearby galaxies. The findings show that young stellar activity drives the evolution of these galaxies, reshaping their interstellar environments. Multiple observations confirm the clusters act as hidden “ring factories” of star formation.

What Happens when a Star Gets Too Close to a Black Hole?
Astronomers have used ultra‑high‑resolution simulations to map how a star is torn apart by a supermassive black hole. The debris forms a thin, coherent stream that repeatedly loops before colliding with itself, releasing a burst of radiation that can briefly outshine the host galaxy. The study shows that black‑hole mass, spin and spin‑orientation dictate the flare’s onset, peak brightness and duration. These tidal disruption events (TDEs) now provide a clearer fingerprint for detecting otherwise invisible black holes.
