Half century attempt of searching for astrophysical gravitational radiation at last is resulted in the first success. The confidential registration of a gravitational wave signal by the LIGO detectors was declared. In its structure it corresponds to the expected signal form produced by the black hole binary coalescence. In this talk we consider technical specifics of detectors, registration details and perspectives of gravitational wave astronomy development. The current status of the OGRAN detector placed in BNO RAS underground is also presented and ways of enhancing its sensitivity are discussed
