Record-Breaking Gamma-Ray Burst Engine Active for Nearly a Month
Astronomers have identified a gamma-ray burst with an unprecedented central engine duration. The event, observed at a redshift of 0.8577, maintained activity for approximately 27 days in its rest frame. This duration shatters the previous record by nearly 20 days, challenging existing astrophysical models. Researchers are currently investigating the specific mechanisms that could sustain such prolonged high-energy emissions.
