The sleeping giant woke up regarding 200 years ago to devour some nearby cosmic bodies before returning to hibernation, according to the study, the results of which were published in the journal Nature on Wednesday. A recent study showed that the massive black hole at the center of our galaxy, the Milky Way, is not lurking as it was thought, as it witnessed in the recent past a strong return to activity following it devoured cosmic bodies on its way. The sleeping giant woke up regarding 200 years ago to devour some nearby cosmic bodies before returning to hibernation. According to the study, the results of which were published in the journal “Nature” on Wednesday. The researchers said that the space observatory “IXPE” of the US Space Agency (NASA) detected an X-ray echo of this strong activity. The supermassive black hole “Sagitrios A” ( Sagittarius A) is 4 million times more massive than the Sun. It is located 27,000 light-years from Earth in the spiral center of the Milky Way galaxy.Last year, astronomers revealed the first image of the black hole, or rather the glowing ring of gas that surrounds its blackness.Frederic Maran, a researcher at the French Astronomical Observatory of Strasbourg, said: The lead author of the study, Sagittarius A, has always been seen as a dormant black hole. Most supermassive black holes in the middle of their galaxies become dormant following swallowing all the material close to them. “Imagine a bear going into hibernation,” Maran told AFP. following devouring everything around it.” But the international team of researchers discovered that around the end of the nineteenth century, “Sagittarius A” came out of its slumber and consumed any unlucky gas and dust that came in its path. The situation continued in this way for a period that ranged from several months to a year, Before the “monster” went back into hibernation. Maran explained that when the black hole was active, it was “at least a million times brighter than it is today.” Its awakening was noticeable because nearby molecular clouds began emitting more X-ray light. He likened the center France’s National Scientific Research Institute (CNRS) described the increase in X-ray light as “a single glowing worm that was hidden in a forest and suddenly became as bright as the sun”. NASA’s X-ray Polarization Imaging) tracked the X-ray light and found that it pointed directly at Sagittarius A. The black hole “emitted an echo of its previous activity, which we were able to detect for the first time,” Maran said. So much so that nothing can escape it, not even light. But when matter is sucked in beyond the black hole’s final boundary, known as the event horizon, it emits a massive amount of heat and light before disappearing into darkness. The cause of Sagittarius’s exit is still er” for a brief period of indistinct stillness. Could a star or cloud of gas and dust have come so close? Astronomers hope that additional observations (from IXPE) will help them better understand what happened, and perhaps reveal more information regarding the origin of supermassive black holes, which are still shrouded in mystery.
