🪐 In the spiral galaxy Messier 74, astronomers have observed a rare "ultra-long" gamma-ray burst—an intense flash of high-energy light caused when a massive star collapses into a black hole, emitting jets that travel for billions of light-years. Gamma-ray bursts like this one are the brightest explosions since the Big Bang, and just a single burst can release more energy in seconds than our Sun will produce in its entire lifetime. ✨ #gamma-rays ⚡#explosions⚡#Messier74⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
