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.

Orion Completes Small Mid-Course-Correction Engine Burn as It Prepares to Swing Around Behind the Moon
NASA’s Orion capsule completed a 17.5‑second mid‑course correction on April 5, 2026, fine‑tuning its trajectory for the Artemis II lunar fly‑by scheduled for the evening of April 6. The crew – astronauts Reid Wiseman, Victor Glover, Christina Koch and CSA’s Jeremy Hansen – will swing behind the Moon, experiencing a 40‑minute communications blackout before coasting back toward Earth. Unlike Apollo 8, Orion will not enter lunar orbit, making the maneuver low‑risk but highly visible. The mission has drawn criticism for limited new engineering validation and lingering concerns over Orion’s heat shield performance after the 2022 uncrewed test.
