The results of a high-resolution processing, based on techniques of fractal dimension analysis and called a method of multilevel dynamical contrasting [1], of numerous data from laboratory electric discharges (Z-pinch, plasma focus) and observations of cosmic plasmas (including available Hubble Space Telescope data) reveal high degree of self-similarity of plasma structuring in a very broad range of length scales. This covers about thirty orders of magnitude: from micrometer thickness of individual filaments in laboratory discharges to the structures in the universe which resemble networking of electric currents in laboratory plasmas. The results presented illustrate recently suggested [1] generic features of electric current networking in plasmas: (1) long-living filamentation of electric current; (2) formation of a fractal structures made of a single filament and complicated interaction of these "fractal" filaments; (3) formation of a percolating network that includes, in particular, formation of a "stocking" woven by the individual filaments.
