Astronomers have mapped more than 25,000 active supermassive black holes in distant galaxies - Our astronomers have helped make a huge map of the night sky showing more than 25,000 active supermassive black holes in distant galaxies. The map is the largest and sharpest ever created at ultra-low radio frequencies. Starry night At first glance it looks like a picture of a starry night sky, but instead what you are really seeing are supermassive black holes that emit radio waves at ultra-low frequencies. The black holes have been captured by LOFAR, currently the world's largest radio telescope operating at lowest frequencies. Scientists used supercomputers to correct for the interference to LOFAR's radio waves caused by the Earth's ionosphere to create their map. Durham is part of the international team involved in LOFAR. Astronomers will use the map to discover celestial objects that only emit ultra-low frequency radio waves.
