The Cosmic Background Imager (CBI) is a radio interferometer designed to study the Cosmic Microwave Background (CMB) radiation, which is the afterglow of the Big Bang. Located in the Atacama Desert of Chile, the CBI was constructed to provide high-resolution images of the CMB's fluctuations across the sky.
