Summary

Story summary

GRB 250702B lasted about a day and featured three explosions, challenging current gamma-ray burst theories.
Initially thought to be local, follow-up observations confirmed its extragalactic origin, billions of light-years away.
Researchers suggest the burst may arise from a white dwarf consumed by an intermediate-mass black hole.
Co-lead authors highlight this event as a major advancement in understanding cosmic phenomena, with further investigations planned.
Findings were published in The Astrophysical Journal Letters.
