Its distance is about 12.8 billion light years, so he appeared not later than 900 million years after the Big Bang. But the current theory of the origin of quasars do not explain the possibility of the existence of such a massive black hole formed so early.
To the formation of a massive black hole was probably less than a billion years, the quasar SDSS J0100 + 2802 it was necessary to pull the interstellar matter in large quantities. At the same time increasing the quasar radiation, according to the calculations, was to interfere with this process.
Direct determination of the distance to distant cosmic objects is not possible. One of the indirect method is to measure the distance from the redshift. Total science now knows about 40 quasars with offset z & gt; 6, and the brightness of the newly discovered quasar (its displacement z = 6.3) exceeds several times the maximum brightness of any of these 40.
The new quasar surpasses all known to him, and brightness and weight i>
Quasars have noticed for a long time, and at first found it difficult to give an explanation of their existence. Now it is assumed that this supermassive black holes with accretion disks of matter around them, and the more substance in them, the more they emit. Quasars emit very active in radio, and in the light range. For example, the brightness of the new quasar approximately 420 trillion times larger than our sun.
The new quasar not only raised interesting questions in astrophysics, but will be help in the study of deep space. Thanks to its radiation, scientists can study the objects that cross the line between the Earth and the quasar.
