Scientists observed GRB 250702B, the longest gamma-ray burst ever recorded, lasting over seven hours and originating from a dusty galaxy 8 billion light-years away, challenging existing models of such explosions and possibly caused by a massive star's death, a black hole merger, or a helium star-black hole interaction.
Scientists observed the longest gamma-ray burst ever recorded, GRB 250702B, which lasted over seven hours and originated from a dusty galaxy 8 billion light-years away, challenging existing models of such explosions and possibly caused by the death of a massive star, a black hole merger, or a related event.
Astronomers observed GRB 250702B, a gamma-ray burst with an unprecedented duration of nearly a day and possible repetition, originating from a large, dusty galaxy over five billion light-years away. Its unusual characteristics suggest it may result from an exotic event such as a massive star collapse, a tidal disruption event, or a black hole-star merger, potentially indicating a new type of cosmic explosion.
