Abstract
A possible existence of cosmologically large domains of antimatter or astro nomical "anti-objects" is discussed. A brief review of different scenarios of baryogenesis predicting a noticeable amount of antimatter is given. Thou gh both theory and observations indicate that the universe is most possibly uniformly charge asymmetric without any noticeable amount of antimatter, s everal natural scenarios are possible that allow for cosmologically (astron omically) interesting objects in close vicinity to us. The latter may be di scovered by observation of cosmic ray antinuclei.
