GRB 250702B: Seven‑hour repeating gamma‑ray burst points to star torn apart by intermediate‑mass black hole
On 2 July 2025 NASA's Fermi telescope recorded GRB 250702B, a repeating gamma‑ray burst that persisted for over seven hours and produced multiple distinct flares across a day — nearly double previous records. A new MNRAS paper argues the source is a star tidally disrupted by an intermediate‑mass black hole.
