Reber Radio Telescope, Radio telescope in Green Bank, United States
The Reber Radio Telescope features a 31-foot diameter parabolic reflector made of iron sheeting mounted on arched rails with railroad wheels for elevation control.
Built in 1937 by astronomer Grote Reber in Illinois, this telescope stands as the first purpose-built parabolic radio telescope and received National Historic Landmark status in 1989.
The telescope represents the beginning of radio astronomy in the United States, enabling scientists to observe and document radio waves from celestial sources like the Milky Way.
Located at the Green Bank Observatory in Pocahontas County, the telescope remains accessible to researchers and visitors interested in early astronomical instrumentation.
The structure incorporates 72 radial rafters covered with 26-gauge iron sheeting and maintains a precise 20-foot focal length for astronomical observations.
