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.

Interstellar Invader 3I/ATLAS Is Spraying Tons of Water Into Space Every Second. Jupiter-Bound Spacecraft JUICE Discovers
The European Space Agency’s Jupiter Icy Moons Explorer (JUICE) has measured the interstellar comet 3I/ATLAS ejecting roughly two tons of water vapor each second—equivalent to 70 Olympic‑size swimming pools per day. The detection was made with JUICE’s MAJIS spectrometer and JANUS camera during an unplanned fly‑by in November 2025, marking the third confirmed interstellar object to traverse the Solar System. Infrared data revealed abundant water and carbon‑dioxide volatiles, indicating that the comet’s interior harbors pristine ices from another star system. Scientists say the findings open a rare window into the chemistry of planetary formation beyond the Sun.
