The astonishing jet of an extreme gamma-ray burst
Gamma-ray bursts (GRBs) are short duration transient phenomena lasting from a few seconds to hundreds of seconds. These bursts are localized on the sky using gamma-ray detectors onboard satellites orbiting Earth. The satellites pinpoint the direction of the burst, allowing astronomers to rapidly point their... click to read more
