  • A. Atacama Pathfinder Experiment
    The Atacama Pathfinder Experiment is a submillimeter-wavelength radio telescope located in Chile’s Atacama Desert, used for studying cold gas and dust in the universe.
  • 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. Caltech Submillimeter Observatory
    The Caltech Submillimeter Observatory was a pioneering radio telescope facility specializing in submillimeter-wavelength astronomy, contributing significantly to the study of cold dust, gas, and star formation in the universe.
  • E. South Pole Telescope
    The South Pole Telescope is a large millimeter-wave radio telescope located at the Amundsen–Scott South Pole Station, designed primarily to study the cosmic microwave background and the large-scale structure of the universe.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
