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.

Researchers Demonstrate Megawatt-Class Ga₂0₃ Module
A research team led by the University of Hong Kong has built a megawatt‑class gallium oxide (Ga₂O₃) power module that can pulse‑switch continuously at 1,000 V and 1,000 A. The device uses a novel junction‑side cooling architecture with a high‑permittivity interface, cutting thermal resistance and boosting breakdown voltage. In a six‑die configuration it achieved 23 ns switching, near‑zero reverse recovery, and sustained junction temperatures above 250 °C at 1 kHz. The work, published in Nature Communications, marks the first UWBG multi‑chip module to reach megawatt‑level power capacity.
