Heinrich Hertz Submillimeter Telescope

The Heinrich Hertz Submillimeter Telescope features a 10-meter parabolic dish housed within a protective building that opens during observations to shield sensitive equipment from harsh weather conditions.

Completed in 1993 and named after Heinrich Hertz, the physicist who confirmed electromagnetic waves, this telescope was specifically designed for submillimeter wavelength radio astronomy observations.

As part of the Event Horizon Telescope network, this facility contributes to groundbreaking black hole imaging research while fostering international scientific collaboration in astrophysics.

Located at 3,185 meters elevation on Mount Graham, the telescope operates nine to ten months annually, with summer observations limited due to increased atmospheric moisture.

The telescope's high-altitude desert location provides exceptionally dry atmospheric conditions essential for detecting submillimeter radiation from cold cosmic objects like molecular clouds and distant galaxies.
