One of the brightest gamma-ray bursts was observed by Czech telescopes


On the night of June 19-20, 2021, visible light from a source 10 billion light-years away from Earth was captured by three telescopes. Two of them – robotic telescopes – are operated by Czech institutions – the D50, located in Ondřejov, is managed by the Astronomical Institute of the Czech Academy of Sciences, while the other, FRAM-ORM, is located on the Spanish island of La Palma. The third telescope, Mini-MegaTORTORA, is installed in Nizhny Arkhyz, Russia. An international team has published a study of this extraordinary source in the May issue of Nature Astronomy.
