A group of international researchers led by the Center for Astrophysics | Harvard and Smithsonian (CfA) achieved the once-unimaginable four years ago: using a groundbreaking telescope to capture an image of a black hole. “What we are trying to do now is launch a space mission that would improve the sharpness of the EHT images by a factor of 10,” Johnson said. This would reveal photon rings — rings made by the light orbiting a black hole. They’re too narrow to distinguish from the rest of the light near a black hole,” he said. “If a black hole is spinning, it would distort the shape of the photon ring, squeezing it into an oval,” Galison said.
