3-515: The Submillimeter Telescope ( SMT ), formerly known as the Heinrich Hertz Submillimeter Telescope , is a submillimeter wavelength radio telescope located on Mount Graham , Arizona, US. It is a 10-meter-wide parabolic dish inside a building to protect it from bad weather. The building front doors and roof are opened when the telescope is in use. The telescope's construction was finished in 1993 . Along with

The dryness of the air around and above Mount Graham is important for extremely high frequency (EHF) radio and far- infrared observations – a region of the spectrum where the electromagnetic waves are strongly attenuated by any water vapor or clouds in
