Researchers from Peking University could not examine the same hole, therefore, focused on the surrounding disk. Hole sucks in surrounding matter with such force that the latter heats up and emits radiation. The brightness of the disk indicates that the black hole that is hidden in it, is extremely powerful.
Fortunately, the object is 12.8 billion light-years from Earth. The distance, however, mean that the hole we have seen from Earth, was formed shortly after the Big Bang, and that it had already reached its capacity. The object that we see in the universe was only 900 million years.
The huge mass of existing holes in the early universe is surprising. This means that such objects appeared in the beginning of our cosmos and very quickly took on weight – which is rare because black holes usually develop quite slowly.
