The Robert C. Byrd Green Bank Telescope has advanced the knowledge of astronomy with some key discoveries. It assisted in observing the first known double-pulsar binary systems, improving astronomers’ understanding of pulsars and allowing the most precise test yet of general relativity. The telescope would have an offset feed arm, meaning the sub-reflector at the focal point would lie outside the path of incident radio waves, increasing the viewing area by as much as 10 percent. Measuring 100 by 110 meters, the telescope’s oval reflector dish has two acres of surface area. The surface would consist of 2004 panels that could be adjusted in and out to fine-tune the shape of the surface. The basic structure of the telescope consists of the rotating lower section, known as the alidade, and the tipping structure, which tilts within it. The telescope operates over a greater band of wavelengths than any telescope before it and points with greater accuracy. It can zero in on targets within an arc-second, the angle subtended by a dime from a mile away.
