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.

Giant Craters May Reveal if Psyche Is a Lost Planetary Core
Scientists used 3‑D impact simulations to probe the interior of metal‑rich asteroid 16 Psyche, focusing on a large north‑polar basin. The models tested homogeneous versus layered structures and varied porosity, revealing that internal void space strongly shapes crater depth‑diameter ratios. Results generate testable hypotheses for NASA's Psyche spacecraft, which will arrive in 2029 to directly measure the asteroid's composition. The work advances the debate over whether Psyche is a stripped planetary core or a primitive planetesimal.
