Underside of the GBT
Standing directly beneath the Green Bank Telescope, the view here is straight up the giant feed arm that supports the GBT’s receivers perched over 480 feet above the ground. The massive 2.3-acre dish surface of the GBT is an enormous bucket for scooping up the weak radio waves that rain down on us from objects in space.
