| By 1962, NRAO had constructed a 300-foot transit paraboloid telescope, steerable only in elevation. Over the next eight years of operation, the wire-mesh surface panels distorted to the point that they had to be replaced. The replacement of the panels, which cost as much as the construction of the telescope itself, was completed in 1970. | A piece of the original wire-mesh surface of the NRAO 300' telescope which was later replaced.

| The Green Bank 300-foot telescope was the first to use a cryogenically cooled receiver system, thus reducing the noise created by the heat of the receiver and allowing the detection of faint signals. With the instrument’s unmatched sensitivity, astronomers were able to discover a pulsar in the Crab Nebula, confirming the belief that pulsars are neutron stars resulting from supernovae events. |
