Using the fluctuation electromagnetic theory and Lorentz transformations, we have developed a self-consistent description of radiation heat transfer and dynamics of large perfectly black spherical bodies when moving in photonic gas with relativistic velocity. Radiation force acting on a body in the reference frame of the background radiation is found along with the rate of heating (cooling) and the power of emitted and absorbed electromagnetic radiation. Apart from the general physical meaning, the results can be used in studying evolution of cosmic bodies and their thermal radiation.
