In 2019, when we saw an image of a black hole for the first time courtesy of the Event Horizon Telescope (EHT), scientists believed that there is more to the image than we saw. Now, in another historical first, astrophysicists have remastered that image to reveal the photon ring of a black hole. The bright, glowing circle is a creation of intense gravity.
