The Submillimeter Array (SMA) is a radio telescope located on Mauna Kea in Hawaii. It consists of eight antennas that work together to observe celestial objects at submillimeter wavelengths, which are between infrared and microwave on the electromagnetic spectrum. This allows astronomers to study cold gas and dust in space, providing insights into star formation and the early universe. The SMA is a collaborative project involving institutions like the Harvard-Smithsonian Center for Astrophysics and the National Astronomical Observatory of Japan. By combining data from its antennas, the SMA achieves high-resolution images, enabling detailed observations of distant galaxies, star-forming regions, and other astronomical phenomena.
