Astronomers have captured unprecedented images of cosmic giants in a very short time span, taking us closer to black hole than ever before. Scientists now see the phenomenon that occurs behind them for the first-time. Researchers captured light from a supermassive dark hole 800 million light-years away as part of this breakthrough.According to Dan Wilkins, a Stanford astrophysicist, the latest discovery is "key piece of the puzzle for understanding" how the universe came about. It also confirms Einstein's theory about relativity, which was established over 100 years ago.Researchers also saw fainter flashes light while studying the bright x-rays from the black hole. This feature is known as the corona. These were the "luminous echos" of flares that bounce off the gas behind a black hole. Einstein first predicted this phenomenon in 1916's theory of relativity.ESAWilkins explained that any light that enters that black hole does not come out. Therefore, we should not be able see anything behind it." That's because the black hole is warping space, twisting magnetic fields and bending light around itself.Supermassive black holes are 10 million times larger than our Sun. They are located in the middle of a nearby spiral galaxy, I Zwicky 1. The echoes were witnessed by an international team of scientists using NASA's NuSTAR space telescopes and the European Space Agency's XMM–Newton space telescopes. The journal Nature published their findings.Wilkins stated that the "color of these flashes and the color of the echoes, as well as the delay after the original flare, told us that these were the echos from the gas that's hiding behind the black hole." It will reflect some of the gas into the blackhole, which gives us a rare view of the material's final moments.
