Fermi Gamma-Ray Space Telescope after the integration of the burst monitor


Known as the Gamma-ray Large Area Space Telescope prior to launch, the Fermi telescope includes two primary instruments: the Large Area Telescope with which astronomers can observe and study active galactic nuclei, pulsars, dark matter signatures, and other high-energy phenomena; and the Gamma-ray Burst Monitor to study gamma-ray bursts. This image shows the assembled telescope in the clean room prior to launch.
