Observations of positron electron annihilation radiation address some fundamental problems in Galactic astrophysics, including nucleosynthesis, supernovae, black holes, and the interstellar medium. The 0.511 MeV line resulting from positron annihilation is superposed on a continuum which probably is, in large part, bremsstrahlung of cosmic ray electrons. The power deposited by these electrons could have important implications for the interstellar medium.
