An important step toward a better understanding of the high energy emission from gamma-ray bursts was just been reached with the detection by the MAGIC cherenkov telescopes of highly energetic photons from a distant gamma-ray burst, GRB 190114C (z=0.42 or 7 billion km). MAGIC (Major Atmospheric Gamma Imaging Cherenkov) is a system of two telescopes, each of 17 meters in diameter, located at the El Roque de los Muchachos Observatory, La Palma, Canary Islands.
