description: The study of a sample of nearby galaxies is a source of important data on the formation and evolution of the large-scale structure of the Universe. Observational data available on Local Volume galaxies are the most accurate and richest, and allow one to characterize the evolution of galaxies in the Â«presentÂ». Therefore, in this work, star formation at low redshifts was studied. For this, the database of galaxies of the Local Volume was used. In the course of work, using data on 1400 galaxies in the Local Volume of the Universe, the average star formation rate (SFR) in a unit volume of the Universe was determined, (1.2 Â± 0.2)10â2 Msun/yr Mpc^3 . At the current rate of star formation over a cosmological time of 13.8 Gyr, about 65 percent of the observed stellar mass is reproduced in the universe. The reserves of neutral gas in the Local volume with a radius of 12 Mpc allow maintaining the current SFR rate on the scale for about 3 Gyr more. The Milky Way extinction zone contributes to the deterioration of the sample from the observed data. âShortage of galaxiesâaccording to rough estimates is 33 percent.
