An international team of astronomers has added 4.4 million new space objects, mostly galaxies and black holes, to the map of the Northern Hemisphere.
Astronomy and Astrophysics indicates that astronomers from the University of Durham in Britain, in cooperation with an international team, discovered a group of astronomical objects thanks to the European Low Frequency Radio Telescope System (LOFAR), which was launched in 2010. This system consists of 20,000 radio antennas installed in 52 locations in Europe. .
The new map includes high-quality radio images of the universe, including the development of new stars, galaxies, black holes and other space objects. Most of these sites are billions of light years away from Earth.
To transfer 3,500 hours of observations to the map, the scientists used modern algorithms on supercomputers. This amount of data took up about eight petabytes of disk space, which is equivalent to the memory of about 20,000 laptop computers.
