A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally. This greatly broadens application spectra of the vortex photons in the field of physical science. Moreover, the finding indicates that vortex photons are ubiquitous in the universe. It paves a way to a completely new research field, natural vortex photon science.
