The results of gamma-ray burst observations made in the 10 keV - 8 MeV range with Konus-B instrument on Granat spacecraft are presented. 19 gamma-ray bursts and 60 solar flares have been measured altogether in 27 days at a sensitivity level of 5×10

Diffuse cosmic background and atmospheric gamma-radiation in the range 28 keV-4.1 MeV were studied with a scintillation spectrometer on board of the Kosmos 461 satellite. Separation of the cosmic and atmospheric components was made possible through a

A review is given of the gamma-ray burst energy spectrum measurements on Venera 11 and Venera 12 space probes. The gamma burst continuum approximates in shape thermal brems-strahlung emission of a hot plasma. The radiation temperature varies over a b

The pair annihilation radiation in gamma-ray bursts is seen as broad lines with extended hard wings. This radiation is suggested to escape in a collimated beam from magnetic polar regions of neutron stars.

Venera 11 and Venera 12 have detected emission and absorption lines in the energy spectra of many γ-ray bursts. The similarity between the spectral features observed during different events reveals the similarity in physical conditions and processes

The event was observed onboard the space probe Venera 11 at a heliolongitude close to 57°. Electron spectra in the energy range from 60 to 2100 keV are determined and compared with X ray spectra. As a result it was found that conditions of the “th

The γ-ray burst detector Konus1, on the Venera 11 and Venera 12 spacecraft, detected on 5 and 6 March, 1979 two bursts of hard X rays originating from the same source. These events are quite unusual and of considerable interest. The burst of 5 March
