El Atacama Large Millimeter/submillimeter Array (ALMA) -el proyecto astronómico más grande que existe- es un telescopio único de diseño revolucionario, compuesto por 66 antenas de alta precisión ubicadas en el llano de Chajnantor, a 5.000 metros de altitud en el norte de Chile.

The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths.

ALMA uses sophisticated atmospheric models, climate monitoring stations and radiometers to measure the amount of water vapor present in the line of vision of each antenna, to correct these undesired atmospheric effects.

The Atacama Large Millimeter/submillimeter Array is the most complex astronomical observatory ever built on Earth. Teams from North America, East Asia, and Europe merged projects to develop this breakthrough scientific instrument in northern Chile.

Scientists foresee record harvests, where invisible light (radio waves) accumulated by ALMA will be vital to our understanding of the Universe. The purpose of ALMA is to study star formation, molecular clouds and the early Universe, closing in on …

Sep 30, 2011 · ALMA is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, galaxies and life itself.

ALMA is an international astronomy facility, and is a partnership between the European Southern Observatory (ESO), the National Science Foundation (NSF) of the United States and the National Institutes of Natural Sciences (NINS) of Japan in collaboration with the Republic of Chile.
