  We show that a tangle of light superconducting strings in the Milky Way could
be the source of the observed 511 KeV emission from electron-positron
annihilation in the Galactic bulge. The scenario predicts a flux that is in
agreement with observations if the strings are at the ~ 1 TeV scale making the
particle physics within reach of planned accelerator experiments. The emission
is directly proportional to the galactic magnetic field and future observations
should be able to differentiate the superconducting string scenario from other
proposals.
