High-Altitude Submillimeter Eye Opens on Chilean Summit
Chile’s Cerro Chajnantor summit hosts the Fred Young Submillimeter Telescope (FYST), a 6‑m instrument designed for rapid, wide-field surveys in submillimeter light using a Crossed-Dragone design and Prime Cam with up to seven detector modules and about 100,000 superconducting detectors. The dry, high-altitude site enables deep, dust-penetrating observations to map the cosmic microwave background, galaxy clusters, star formation, and the epoch of reionisation. Built for CCAT Observatory by an international collaboration, FYST represents 34 years of effort and will soon begin delivering unprecedented views of the universe.
