According to the new study, scientists have calculated and predicted an intricate internal structure within black hole images caused by extreme gravitational light bending. The study has been published in Science Advances. In this, the lead author Michael Johnson of the Center for Astrophysics Harvard and Smithsonian has described how the swirling ring of photons around a black hole could be the key to unlocking sharp photos. "The image of a black hole actually contains a nested series of rings," Johnson tells IFLScience. "Each successive ring has about the same diameter but becomes increasingly sharper because its light orbited the black hole more times before reaching the observer. With the current EHT image, we’ve caught just a glimpse of the full complexity that should emerge in the image of any black hole." By stacking images of a black hole’s “subrings,” we may one day be able to create a much sharper complete photo of what a black hole looks ...
