  • A. Joint ALMA Observatory
    The Joint ALMA Observatory is the international organization responsible for managing and operating the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope facility in Chile.
  • B. Atacama Large Millimeter/submillimeter Array
    The Atacama Large Millimeter/submillimeter Array is a powerful astronomical observatory composed of dozens of radio antennas that study the cold universe—such as star and planet formation—by observing millimeter and submillimeter wavelengths.
  • C. Atacama Compact Array
    The Atacama Compact Array is a subset of smaller, closely spaced radio telescopes within the ALMA observatory designed to improve imaging of extended astronomical objects at millimeter and submillimeter wavelengths.
  • D. Submillimeter Array
    The Submillimeter Array is a radio interferometer of eight 6-meter telescopes that observes the universe at submillimeter wavelengths, enabling high-resolution studies of cold gas, dust, and star-forming regions in space.
