Black holes absorb everything that falls into them, even radiation. And yet, astronomers have detected X-ray radiation coming from black holes, and this has been an unsolved mystery since the 1970s. Researchers have built a detailed simulation of the environment around a black hole, modeling the interactions between radiation, plasma, and magnetic fields. They found that the turbulence of the magnetic fields heats the local plasma and makes it radiate in X-rays.
