TL;DR

Astronomers have discovered a record-breaking, unusually long gamma-ray burst, GRB 250702B, which lasted about a day and originated from a galaxy billions of light-years away. Its peculiar duration and repeated signals challenge existing theories about such cosmic explosions, suggesting a possible involvement of an intermediate black hole and a white dwarf, but the exact cause remains unknown.
