The Robert C. Byrd Green Bank Radio Telescope (GBT) focuses 2.3 acres of radio light. It is 485 ft tall, nearly as tall as the nearby mountains and much taller than pine trees in the national forest. The telescope is in a valley of the Allegheny mountains to shield the observations from radio interference.
