The Atacama Large Millimeter Array (ALMA) The Atacama Pathfinder Experiment (APEX), a new-technology 12-m telescope in operation since 2005 on Llano de Chajnantor. The Atacama Large Millimeter Array (ALMA) is a large submillimetre radio telescope interferometer at Llano de Chajnantor, consisting of 54 big 12 m (39 ft) and 12 smaller 7 m (23 ft) parabolic antennas.
The University of Tokyo Atacama Observatory (TAO) is an astronomical observatory located on the summit of Cerro Chajnantor, at an altitude of 5,640 m (18,500 ft) within a lava dome in the Atacama Desert of northern Chile. [1]
The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau – near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. This location was chosen for its high elevation and low humidity , factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. [ 1 ]
It is a 1.45 billion euros ($1.51 billion) project of the European Southern Observatory intergovernmental research organization. "It's going to impact practically all areas of astronomy.
The Atacama Desert (Spanish: Desierto de Atacama) is a desert plateau located on the Pacific coast of South America, in the north of Chile.Stretching over a 1,600-kilometre-long (1,000-mile) strip of land west of the Andes Mountains, it covers an area of 105,000 km 2 (41,000 sq mi), [2] which increases to 128,000 km 2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
The cold Humboldt Current and the Pacific Anticyclone are essential to keep the dry climate of Atacama Desert. The average rainfall in the Chilean region of Antofagasta is just 1 mm per year. Some weather stations in the Atacama have never received rain. Evidence suggests that the Atacama may not have had any significant rainfall from 1570 to ...
Paranal Observatory is an astronomical observatory operated by the European Southern Observatory (ESO). It is located in the Atacama Desert of Northern Chile on Cerro Paranal at 2,635 m (8,645 ft) altitude, 120 km (70 mi) south of Antofagasta .
The Atacama Pathfinder Experiment (APEX) is a radio telescope 5,064 meters above sea level, at the Llano de Chajnantor Observatory in the Atacama Desert in northern Chile, 50 km east of San Pedro de Atacama built and operated by three European research institutes.
