| contents | Based on the fluxes of 1400 nearby galaxies observed in far ultraviolet (${\rm FUV}$) and in the H$α$ line, we determined the global star formation rate per unit Universe volume, $j_{\rm SFR}=(1.34\pm0.16) 10^{-2}\,M_{\odot}$ yr$^{-1}$ Mpc$^{-3}$. With the current star formation rate (SFR), ($65\pm4)$% of the observed stellar mass is reproduced in the cosmological time of 13.8 billion years. The neutral gas reserves in the Local Volume with a radius of 11 Mpc will facilitate the current SFR on a scale of approximately another 5 billion years. |
