A supermassive black hole is depicted in this artist's concept, surrounded by a swirling disk of material falling onto it. The purplish ball of light above the black hole, a feature called the corona, contains highly energetic particles that generate X-ray light. The corona gathers inward, becoming brighter, before shooting away from the black hole. NASA/JPL-Caltech
