Almost at the "edge of the universe" – the quasar QSO J0831+5245


Thomas Grunge and Gerold Holtkamp imaged the quasar QSO J0831+5245 on May 14th 2020 with the Cassegrain telescope (60 cm mirror diameter, 746 cm focal length) of the NVO Observatory. Its speed alone is record-breaking: 276,000 km/s (according to Simbad). Its light was about 12.05 billion (!) light years on its way until it reaches us on Earth.
