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.

Beach-Scale Tidal Variations Observed From Satellite-Derived Shoreline Time Series
Researchers demonstrate that satellite‑derived shoreline time series can resolve fine‑scale tidal dynamics along coastlines. By applying harmonic and response‑based analyses to optical imagery, they extract multiple tidal constituents, including the solar S₂ and the dominant M₂, and validate results against tide gauges and altimetry. A variational Bayesian harmonic estimator identifies statistically significant M₂ trends around New Zealand consistent with in‑situ observations. The study positions shoreline measurements as a cost‑effective tool for coastal tide model validation and monitoring.
