NASA has detected the longest gamma-ray burst ever recorded, an extreme cosmic explosion that lasted nearly seven hours — far longer than typical gamma-ray bursts, which usually fade within seconds or minutes. This unprecedented event is believed to have occurred when a black hole plunged into a massive star, tearing through it from the inside while feeding on stellar material. As the star collapsed, the black hole formed a hot spinning accretion disk and launched powerful relativistic jets, rel

🚨The Longest Cosmic Explosion EVER Caught!

Watch NASA’s animation of a star being torn apart from within. 🌌 GRBs happen almost daily — but nothing like this one. 🎥 Credit:
