Scientists have observed for the first time what’s behind a black hole: their gravitational pull bends the rays of light around them
They are unexpected bright echoes, flashes. In other words, X-ray flares, which were first observed by astronomers behind a black hole. An important step forward in understanding our universe. Unexpected this light, which is behind a supermassive black hole in the center of a galaxy 800 million light years away. Scientists spotted it while they were studying a feature known as corona. Material falling into a supermassive black hole powers a continuous light source, and as it does, forms a corona around the black hole. This light – which is X-ray light – can be analyzed to map and characterize the celestial body. But in the meantime, they have observed a new, unexpected phenomenon that they are now analyzing.
This light behind the black hole becomes even more important because confirms Albert Einstein’s theory of general relativity. The gravitational pull of black holes essentially fold the rays of light around. And for the first time, astronomers have been able to observe what lies behind these mysterious celestial bodies. Fifty years ago – he declared Roger Blandford, co-author of the research published in Nature, to the Guardian – when astrophysicists began to speculate on how the magnetic field might behave near a black hole, they had no idea that one day we would have the techniques to observe it directly. And now that it is possible, the theory of the greatest scientist in modern history seems to be confirmed. He adds Dan Wilkins, Stanford University astrophysicist: Any light that goes into that black hole doesn’t go out, so we shouldn’t be able to see anything that is behind the black hole. The reason we can see it is that that black hole is warping space, bending light and twisting the magnetic fields around it.
