Scientists have detected a light behind the black hole which proves Albert Einstein's theory of general relativity. A study published in Nature by Stanford University astrophysicist Dan Wilkins and his colleagues were observing X-rays released from a massive black hole which is located at the centre of a galaxy which is 800 million light-years from Earth.
Wilkins and his colleagues furthermore recorded from their telescopes that additional flashes of smaller X-rays and of different colours than the bright flares. The study states that at such a high temperature, the electrons separated from atoms and a magnetic field is created.
The magnetic plasma then breaks as it arch high above the massive black hole and then bends towards it and produces high-energy electrons which subsequently produce X-rays. The scientists stated that a series of smaller flashes were the same X-ray flares but were reflected from behind the black hole.
According to the study, the observations were made using two space-based X-ray telescopes that were, NASA's NuSTAR and the European Space Agency's XMM-Newton.
At present, more observations needed to understand these black hole coronas. The European Space Agency's Athena which is their upcoming X-ray observatory will launch in 2031 that will help make the observations which will make the study much clearer.
