Atacama Cosmology Telescope Panorama, Chile

The Atacama Cosmology Telescope (ACT) is a six-metre telescope on Cerro Toco in the Atacama Desert in the north of Chile, near the Llano de Chajnantor Observatory. It is designed to make high-resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB). At an altitude of 5,190 metres (17,030 ft), it is one of the highest permanent, ground-based telescopes in the world.

Erected in the (austral) autumn of 2007, ACT saw first light on 22 October 2007 with its science receiver, the Millimeter Bolometer Array Camera (MBAC), and completed its first season in December 2007. It began its second season of observations in June 2008.

The project is a collaboration between Princeton University, Cornell University, the University of Pennsylvania, NASA/GSFC, the Johns Hopkins University, the University of British Columbia, NIST, the Pontificia Universidad Católica de Chile, the University of KwaZulu-Natal, Cardiff University, Rutgers University, the University of Pittsburgh, Columbia University, Haverford College, West Chester University, INAOE, LLNL, NASA/JPL, the University of Toronto, the University of Cape Town, the University of Massachusetts Amherst and York College, CUNY. It is funded by the US National Science Foundation.
