The existence of intergalactic dust has been proved by the following observational facts : the decrease of the numbers of distant galaxies and clusters of galaxies behind the central regions of near clusters of galaxies; the different distributions of RR Lyrae stars and galaxies near i Microscopii (Hoffmeister’s cloud); the dependence of colour excesses of galaxies on supergalactic coordinates as well as on the surface density of bright galaxies; the colour index vs redshift correlation of quasistellar objects. The densities of intergalactic dust are estimated to be between 5 × 10−30 g cm−3 (near the centers of clusters of galaxies) and 2 × 10−34 g cm−3 (in general intergalactic space), The grains may be formed either in the early phases of the Universe (25 < z < 50) or may be expelled from galaxies by the radiation pressure. The most effective destruction process seems to be the evaporation by soft cosmic rays.
