submillimeter wave astronomy

The study of the universe in the last waveband of the electromagnetic spectrum to be explored from Earth: the submillimeter window, which extends between wavelengths of about 0.3 to 1 millimeter. This bandwidth is ideally suited for studies of the structure and motions of the matter that forms stars; of the spiral structure of galaxies, as outlined by their giant molecular clouds; and of quasars and active galactic nuclei. The submillimeter window lies between the longest infrared wavelengths and the short radio waves in the millimeter band.
