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.

Inside a Bold Plan to Pulverize an Earth-Bound Asteroid
Researchers at UC Santa Barbara propose "Pulverize It," a planetary‑defense concept that would shatter hazardous asteroids using Falcon 9‑launched penetrators, ranging from tungsten rods to nuclear explosives. Simulations on NASA supercomputers suggest fragments sized 13‑16 feet would vaporize in Earth’s atmosphere, minimizing ground impact. The approach targets both short‑notice and long‑notice threats, offering a blanket solution where traditional deflection methods like NASA’s DART may lack sufficient warning time. While technically viable, the plan faces policy hurdles, especially regarding nuclear detonations in space, and seeks integration with U.S. defense structures.
