Night Sky Over the 140-foot Telescope
The world’s largest polar-aligned telescope is this radio telescope in Green Bank, West Virginia. The telescope’s axis is aimed at Polaris (The North Pole, or area below the North Star) so that it can follow the sky as the Earth spins. In this photograph, we are able to view the 140-foot (43-meter) telescope from the south and lit against the dust-shrouded heart of our Milky Way galaxy.
