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.

Artemis 2 Returns to the Pad for April Launch Attempt
NASA’s Artemis 2 mission rolled back to Launch Complex 39B on March 20 and is now positioned for a launch window opening April 1. The rollout followed a February‑March fix of a helium‑line seal that caused upper‑stage blockage and hydrogen leaks during earlier wet‑dress rehearsals. NASA will skip another fueling test, aiming to fully tank the vehicle and receive a go‑for‑launch within the six‑day window. The agency also outlined future Artemis schedule tweaks, including a new low‑Earth‑orbit test flight in 2027 and a shift to Centaur upper stages for later missions.
