A view of the sky seen in gravitational waves in a wide frequency range ∼10^–9-10³Hz is considered. Stochastic gravitational wave background (GWB) produced by binary systems both galactic and extragalactic in origin is studied in more detail. A realistic "map" of the GW sky is constructed for the first time based on the observed stellar matter distribution within ∼50Mpc from the Sun according to the Tully Catalog of Nearby Galaxies. This map accounts for both the binary produced stochastic GWB and GW radiated during supernova explosions. The total event rate of supernova explosions from the nearby galaxies is found to be about 40 per year. The coalescence rate of binary neutron stars in these galaxies is about 1 per year. We further study the "transparency" of the galactic stochastic GWB for observations made with GW detectors of different angular resolution. Critical frequencies above which the galactic and extragalactic GWB become transparent for a GW detector with 1^o angular resolution were found to be about 2x10^–3Hz and ∼10Hz, respectively.
