Gamma-ray bursts are the most intense explosions in the universe. Now, astronomers are reporting in Nature magazine that they have observed two such bursts. The two MAGIC telescopes on La Palma have recorded the strongest burst of this kind to date with GRB 190114x. And the 28-meter telescope from the H.E.S.S. array in Namibia - the largest telescope of its kind in the world - reports the observation of the GRB 180720B burst, which is also very high-energy. With the measurements, the astrophysicists succeeded in proving that such cosmic flashes at the highest energy range do actually glow, something that had only been assumed for a long time.Gamma-ray bursts are fleeting, lasting from just a few seconds to a maximum of a few minutes. They are probably caused by supernovae - the bursting of massive stars - and the melting of neutron stars or black holes. The gamma-ray bursts of the direct outbreak itself usually produce several thousand to a million times more high-energy than visible light and can only be observed from satellites.Space observatories have however already been able to prove the existence of individual photons that have even more energy. To date, however, up to what energy level ...
