It is believed that the formation of supermassive black holes with the mass of millions and billions of times the mass of the Sun is the initial stage in the formation of galaxies. Hole absorbs the surrounding material, forming the accretion disk. So there are quasars — active galactic nuclei. This is one of the brightest astronomical objects in the visible Universe.

The discovery was made using the Magellan telescope in the Observatory on Las Campanas in Chile, the large binocular telescope in Arizona and the Gemini Observatory telescope in Hawaii. Astronomers discovered a quasar and a black hole got the name ULAS J1342 0928. Objects are 13.1 billion light years from the Solar system.

The black hole mass, according to calculations, is 800 million solar masses. She appeared 690 billion years ago, when the universe was formed only by 5% from its current state. Prior to this, the most ancient quasar and a black hole was considered to be a pair of ULAS J1120 0641, later formed 750 million years after the Big Bang and is located 13.04 billion light years from Earth.

So far, astronomers are at a loss to explain how a black hole so quickly able to reach such gigantic proportions. They expect that study to learn more about how black holes grow and how they affect the space. In addition, the black hole was formed in the period of reionizatsii when filled the Universe with hot ions began to cool, forming hydrogen, which allowed light to spread in space. A number of studies have demonstrated that reionization could be caused by the appearance of black holes.
