One of the few remaining unexplored regions of the electromagnetic spectrum accessible to ground-based astronomical observations lies at wavelengths between 1 and 0.3 mm. Using the new generation of large submillimetre-wave telescopes which have recently been completed in Hawaii, Europe and Chile, astronomers have been actively studying a wide range of astrophysical problems related to the Solar System, the physics of star formation, the chemical and dyunamical evolution of the interstellar medium, the structure and evolution of galaxies, and the nature and energetics of active galactic nuclei and quasars. This spectral region is well suited to the study of gas and dust in the interstellar medium, particularly in its ability to sample regions which are highly opaque at optical wavelengths. The first results from these new telescopes, especially those relating to the interstellar medium, were discussed at two recent meetings
