Astronomers observe fast growing primitive black holes
Quasars are active and very powerful black holes at the centre of distant galaxies. The black holes are extremely massive weighing between 100 million and 10 billion solar masses and rotating around the super massive black hole is a disc of gas and dust. The inner ring of the disc moves faster than the outer rings. The movement causes the material in the rings to rub against each other, heating it and causing it to emit light. Near to the black hole it becomes so hot that X-ray radiation is emitted, farther out ultraviolet light is emitted, then visible light and farthest out infrared radiation. Even though the radiation is coming from a very small area the size of our solar system, it is so powerful that it can be seen across the universe...
