Imagine a star going out with a bang so wild, it tosses the science textbooks out the window. Astronomers just caught a supernova (SN 2021yfj) that’s missing its usual outer layers—no hydrogen or helium, just the heavy stuff from deep inside. It’s like seeing the star’s guts on display! This rare cosmic reveal is making scientists rethink how massive stars die and what they leave behind. Could this be a whole new class of stellar explosion? #Science #supernova #space
