Submillimeter Array (SMA)

The Submillimeter Array (SMA) receives millimeter and submillimeter radiation, so named because its wavelength ranges from 0.3 to 1.7 millimeter, or 0.01 to 0.07 inches. The main source of millimeter and submillimeter radiation is cold interstellar material. It consists of gas, dust and small rock-like bodies. This material is also the substance out of which stars and planets are formed. [Source: Wikipedia]
