Atacama Cosmology Telescope

Caption: The Atacama Cosmology Telescope (ACT) in the Atacama Desert of northern Chile, with Cerro Toco volcanic peak in the background. Astronomers conducted a large, uniform survey of the southern sky with ACT, using a breakthrough technique that detects "shadows" of galaxy clusters on the cosmic microwave background radiation. The shadows pointed astronomers to previously unseen massive galaxy clusters.
