🪐 Supernova SN 2016gkg, discovered in the galaxy NGC 613, gave astronomers their first direct images of a star just hours before it exploded. By comparing "before and after" photos, scientists identified the doomed star—a yellow supergiant about 20 times the mass of our Sun—providing crucial evidence for how massive stars end their lives and offering a rare look at the final moments before a cosmic blast. ✨ #supernovae⚡#ngc613⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
