The Southern Astrophysical Research (SOAR) Telescope is a 4.1 meter aperture telescope designed to produce the best quality images of any observatory in its class in the world. It was funded by a partnership among the Ministério da Ciência, Tecnologia, e Inovação (MCTI) da República Federativa do Brasil, the U.S. National Optical Astronomy Observatory (NOAO), the University of North Carolina at Chapel Hill (UNC), and Michigan State University (MSU). SOAR is situated on Cerro Pachón at an altitude of 2,700 meters (8,775 feet) above sea level, at the western edge of the peaks of the Chilean Andes.
