And this celestial body had spent about a year swallowing various cosmic bodies before entering a state of dormancy that lasted about two hundred years. Frederick Marin, the study author, said that this hole is like a bear that entered a state of hibernation after it devoured everything around it. Marin added that during this phase of activity in the late 19th century, the black hole was “a million times brighter than it is today”. Scientists noticed the hole’s activity again after noticing that the hole’s galactic molecular clouds began to glow … and suddenly became As bright as the Sun. Astronomers tracked the light emitted by the hole using NASA’s X-ray Polarimetry Explorer (and indeed found it to be a hole sleeping thousands of years ago that has begun to become active again). The re-emergence of the black hole remains a mystery, but one prevailing hypothesis is that a star or cloud of gas may have drifted too close to it, awakening the hole from its dormant state, and the researchers hope the study will provide important insights into what drives black holes. Last year, astronomers published online the first ever images of a black hole — or more specifically, the glowing ring of gas that surrounds it and confirms its existence.
