COSI Telescope Comes Together
UC Berkeley engineers and managers watch as the COSI (Compton Spectrometer and Imager) detector assembly is slowly raised from a table in this July 8, 2026, image.

UC Berkeley engineers and managers oversee the assembly of the COSI (Compton Spectrometer and Imager) telescope detector, as seen in a July 8, 2026 photo. The detector is composed of four silver components, each covering flex circuits that transmit signals from the detectors to readout electronics. COSI is a wide-field gamma-ray telescope designed to investigate energetic events across the Milky Way and beyond, such as the formation and annihilation of matter and antimatter, as well as the final stages of star life.
This mission is a collaborative effort involving UC Berkeley's Space Sciences Laboratory, UC San Diego, the Naval Research Laboratory, NASA's Goddard Space Flight Center, Northrop Grumman, Space Dynamics Laboratory, the Italian Space Agency, and various research institutions.
