Atacama Large Millimeter Array
(large radio telescope array in Chile)
The Atacama Large Millimeter Array (ALMA)
is an interferometer array of radio telescopes on
the Chajnantor Plateau
in the Atacama Desert in Chile.
It sits at an altitude of 5000 meters and consists of
66 12-meter and 7-meter movable dishes that
observe millimeter and sub-millimeter wavelengths.
It began operation in 2013 with 50 12-meter dishes,
having been under construction since 2003.
A later addition called the Atacama Compact Array (ACA)
consists of sixteen additional 12-meter and 7-meter dishes
with different specifications, including a wider field of view.
ALMA is currently producing among the most detailed images of many
phenomena (within its wavelength-range) with angular resolutions
varying down to less than fifteen milliarcseconds.
