The Atacama Large Millimeter Array is a sophisticated radio interferometer designed for high-resolution astronomical observations at millimeter and submillimeter wavelengths. It utilizes an array of multiple interconnected antennas distributed over a large area to achieve enhanced angular resolution, allowing astronomers to detect faint signals from celestial objects. This capability makes it instrumental in studying processes such as star and planet formation, analyzing the atmospheres of exoplanets, and mapping the distribution of cold molecular gas throughout the Milky Way galaxy. By observing the faint radio emission from these cosmic sources, the array provides crucial data regarding the physical conditions and chemical composition of distant, early-stage cosmic structures.
