The Galactic Magnetic Field,ctic supernova remnants, pulsars, and neutral hydrogen clouds, as well as observations of the non-thermal galactic background radiation, give information about the magnetic fields in interstellar space. This information is complemented by data on the optical polarization of starlight.
