National Radio Astronomy Observatory

This site is home to the Karl G. Jansky Very Large Array astronomical radio telescope, one of four major telescopes operated by the National Radio Astronomy Observatory (NRAO). The VLA is the most scientifically productive ground-based telescope in the world. Our visitor center and interpretive film will get you oriented to the purpose and function of the telescope, and a self-guided tour path will take you up close to one of the VLA's 27 230-ton dish antennas.
