Workers on the 300-foot

Paths of sturdy panels were installed and painted on the surface of the 300-foot telescope in Green Bank, West Virginia to allow engineers to access the receiver feeds.

A telescope that couldn’t spin

The 300-foot telescope in Green Bank, West Virginia was a transit telescope, meaning that it could only lift and dip, not spin around on its base. In this photo, the 300-foot (after its 1970 surface upgrade) impressively poses at an angle, showing off how well balanced it was on its semi-circle gear. Its upgraded control building is directly beneath it.

Newspaper article claiming 300-foot telescope was attacked by aliens

Zapped by Aliens?

On the night of November 15, 1988, the 300-foot telescope in Green Bank. West Virginia collapsed. Before official investigations discovered the cause as a worn metal gusset plate, theories abounded. One example of those theories is shown on the cover of this newspaper, saying that the telescope was attacked by “hostile space aliens.”

One arm of the VLA

The southwest arm of the three-armed Very Large Array is dotted with antennas for miles across the Plains of San Agustin in New Mexico. The VLA antennas are picked up and hauled along rail tracks several times a year to sharpen or deepen its view of the radio cosmos. At its widest separation, the outlying VLA antennas are 22 miles apart. The yellow Antenna Assembly Building is near the middle of this photo.

The VLA Array looking away

The antennas of the Very Large Array (VLA) observe the radio skies for an estimated 5000 hours each year. Scientists from around the world must submit proposals between February 1 and August 1 to use specific configurations of the VLA. See the most recent configuration schedule here.

Lining up the VLA antennas

There are 27 dish antennas within the Very Large Array that are identical 25-meter telescopes working together as one. This photo shows the array in its most compact configuration, but during other times of the year, the antennas will move farther apart. The movement of these telescopes is similar to the zoom function on a camera, as the telescopes more farther away from each other they capture a larger picture of a portion of the universe.

The National Radio Astronomy Observatory is a facility of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
	The U.S. National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
	AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
