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.

The Martyrs, Hunters, and Nature Lovers Who Came Together to Save Birds
James McCommons’s new book *The Feather Wars* chronicles how the 1914 death of Martha, the last passenger pigeon, ignited a coalition of hunters, scientists, wardens, artists and politicians to protect America’s birds. The narrative reveals how sport hunters pushed for game laws, how women such as Florence Miriam, Mabel Osgood Wright and Rosalie Edge created the first private refuges, and how early scientific practices both harmed and later helped avian study. McCommons links those historic battles to today’s alarming bird declines—one‑third of species lost—while highlighting modern tools like the Merlin app that offer hope for a new conservation wave.
