The Atacama Large Millimeter/submillimeter Array (ALMA) is one of the largest and most advanced astronomical observatories in the world, specifically designed for studying light from some of the coldest objects in the universe. Situated on the Chajnantor plateau in the Chilean Andes at an altitude of over 5,000 meters, ALMA provides exceptionally clear and dry conditions ideal for observing the universe at millimeter and submillimeter wavelengths. This international partnership involves North America, Europe, East Asia, and the host country, Chile.

ALMA consists of 66 high-precision antennas, which work together as a single telescope through a technique called interferometry. This setup allows scientists to explore the formation and chemical composition of stars and planetary systems, investigate interstellar clouds and the complex organic molecules within them, and provide insights into the physics of black holes and distant galaxies. The array’s capabilities are pivotal in advancing our understanding of the cosmos, particularly in the study of phenomena that are not visible in optical light.
