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.

Saskatchewan Spring Runoff Should Be Normal, Below Normal
The Water Security Agency’s spring runoff outlook shows most of Saskatchewan will see near‑to‑below‑normal runoff. The southwest, from Kindersley to Assiniboia, is projected well below normal, while eastern areas near Yorkton should experience normal conditions. Recent fall precipitation was below average, but winter snowpack remains near normal, with mountain snowpack above average. Consequently, Lake Diefenbaker may receive above‑normal inflows, though several southern reservoirs stay below normal levels.
