Gamma-Ray Observatory:

see gamma-ray astronomygamma-ray astronomy,
study of astronomical objects by analysis of the most energetic electromagnetic radiation they emit. Gamma rays are shorter in wavelength and hence more energetic than X rays (see gamma radiation) but much harder to detect and to pinpoint.
