Anti-stars in the Milky Way and primordial black holes

Astronomical data of the several recent years, which present an evidence in favour of abundant antimatter population in our Galaxy, Milky Way, are analysed. The data include: registration of gamma-rays with energy 0.511 MeV, which surely originate from electron-positron annihilation at rest, very large flux of anti-helium nuclei, discovered at AMS, and 14 stars which produce excessive gamma-rays with energies of several hundred MeV which may be interpreted as indication that these stars consist of antimatter. Theoretical predictions of these phenomena, made much earlier ago are described
