Story summary

The Atacama Large Millimeter/submillimeter Array (ALMA) operates in northern Chile's high-altitude desert, starting in 2011.
It involves collaboration among scientists from Europe, North America, East Asia, and Chile to study distant cosmic regions.
ALMA features 66 high-precision antennas, reconfigurable for optimal observation, chosen for its dry conditions to reduce atmospheric interference.
A recent snowstorm temporarily halted observations, but operations resumed after the snow melted.
