🪐 Supernova 1993J in the galaxy Messier 81, about 11 million light-years from Earth, stunned astronomers when it exploded unusually brightly and faded much faster than typical supernovae. This stellar blast revealed clear evidence of two stars orbiting closely together—one feeding material to the other—helping scientists confirm that some supernova explosions are triggered by the complex dance of binary stars, not just the death of single massive stars. ✨ #supernova⚡#binary⚡#star⚡#M81⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
