The Cerro Chajnantor Atacama Telescope (CCAT) is a proposed 25 metres (82 ft) diameter telescope that is intended to reveal the cosmic origins of stars, planets, and galaxies with its submillimeter cameras and spectrometers enabled by superconducting detector arrays. The telescope was originally called the Cornell Caltech Atacama Telescope. On September 14, 2020, the CCAT-p telescope was renamed to be the Fred Young Submillimeter Telescope (FYST) after Fred Young, a Cornell alumnus who has supported the telescope for about two decades with over US$16 million.
