Simple questions like that can have seriously complex answers. In this case, a team of theoretical physicists propose that superhot neutron star cores are creating and blasting out axions, which then generate high-energy photons when they interact with the blisteringly powerful magnetic fields surrounding the neutron stars, and that in turn can be seen as an excess of X-rays from them.
