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.

Billions of Beetles Blanket the Coastlines of Scotland
A massive surge of heather beetles has blanketed Scotland's Caithness coastline, with billions of dead insects washing ashore. The beetles' larvae inject enzymes that kill heather, turning the iconic purple moorland into dry, brown “ghost heather.” This vegetation loss heightens wildfire risk and threatens the region’s tourism and estate values. Scientists link the outbreak to climate‑driven shifts that favor beetle reproduction.
