Dust around galactic nuclei significantly affects the measurement of their distances in the Universe. This was discovered by a team of physicists led by Michal Zajacek from the Masaryk University in Brno, who analyzed ultraviolet and X-ray data from a set of 58 active galaxies. Using two different methods, astrophysicists have studied the distances of these galaxies, called quasars. The ne
