The diameter of the galaxy NGC 1277 is about a quarter of the milky way, with a massive black hole in its center. Astronomers know that the relationship between the mass of the black hole and the mass of stars in the center of the galaxy is totally rare. The black hole represents about 0.1% of the mass of the stars, compared to 59% of the mass of the black hole. The black hole with such a mass relation does not correspond to the theory developed by astronomers for the formation of galaxies and black holes. One of the explanations is the poor measurement of the mass of the black hole and another is that, given the singularity of the galaxy NGC 1277 in the current universe (typical of the Universes of 10,000 million years ago), it is a "memory" of the ancient characteristics. Researchers at the Max Planck Institute of Astronomy have unveiled the discovery in the journal Nature.
