In a jaw-dropping discovery that reads like something from a sci-fi epic, astronomers have spotted two galaxies locked in a brutal cosmic duel. For the very first time, scientists have direct evidence of one galaxy using a powerful quasar—like a cosmic flamethrower—to hammer its neighbor with intense radiation, shredding its star-forming gas and effectively “sterilizing”

Neutrinos—often called the universe’s “ghost particles”—continue to puzzle scientists with their near-light-speed travel and minimal interactions with ordinary matter. A groundbreaking new experiment has just slashed the estimated upper limit on their mass by nearly half, delivering the most precise constraint yet and potentially reshaping our view of these elusive particles. This discovery, based on
