Imagine a cosmic explosion so wild it lasted over 7 hours—way longer than anything scientists have ever seen! NASA’s Fermi telescope caught this record-breaking gamma-ray burst (GRB 250702B) 8 billion light-years away, and it’s got astronomers totally stumped. They think it might be from a rare kind of star death or a black hole merger, but no one’s sure yet. Space is seriously full of surprises! #Science #SpaceMystery #GammaRayBurst
