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.
Latest observation by GRANDMA network allows scientists to set limits on specific astrophysical phenomena. Astronomers were looking for gravitational waves to see events invisible to optical and radio telescopes.
