Llano de Chajnantor Observatory is an astronomical observatory located at 5104 m altitude in the Chilean Atacama desert, 50 kilometers to the north of San Pedro de Atacama. It is a very dry site - inhospitable to humans - but an excellent site for submillimetre astronomy. Water vapour absorbs and attenuates submillimetre radiation and thus a dry site is required for this type of high-frequency radio astronomy. It hosts some of the largest and most expensive astronomical telescopes in the world, with about 1 billion US dollars already allocated for projects on the site.
Telescopes on the Llano de Chajnantor site
- Cosmic Background Imager (CBI)
- Atacama Pathfinder Experiment (APEX)
