Story summary

The gamma-ray burst GRB 250702B lasted nearly seven hours, a record length that challenges existing theories.
The burst originated from a distant, dust-filled galaxy and emitted a narrow jet of material traveling near the speed of light.
Researchers from the University of North Carolina at Chapel Hill participated in a global effort to study the event.
Possible causes include the collapse of a massive star or the merger of stellar remnants, and the findings will serve as a benchmark for future studies.
