Researchers observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole. The flares echoed off of the gas falling into the black hole, and as the flares were subsiding, short flashes of X-rays were seen - corresponding to the reflection of the flares from the far side of the disk, bent around the black hole by its strong gravitational field.
