First detection of gamma-ray burst afterglow in very-high-energy gamma light

After a decade-long search, scientists have for the first time detected a gamma-ray burst in very- high-energy gamma light. This discovery was made in July 2018 by the H.E.S.S. collaboration using the huge 28-m telescope of the H.E.S.S. array in Namibia. Surprisingly, this Gamma-ray burst, an extremely energetic flash following a cosmological cataclysm, was found to emit very-high-energy gamma-rays long after the initial explosion.
