The Submillimeter Array

The Submillimeter Array (SMA) is the world's first imaging interferometric telescope to operate in the major atmospheric windows from 0.3mm to 1.3mm. Located at the summit of Mauna Kea 13,386 feet above sea level, the array consists of eight 6-m movable antennas that can be positioned in different locations to provide highest angular resolution equivalent to an antenna of 0.5 km (0.3 miles) across.
