| NRAO Very Large Array |
 |
Located on the Plains of San Agustin, west of Socorro, New Mexico at Lat N 34°04'43.497" / Long W 107°37'03.819" , the Very Large Array (VLA) was approved by congress in 1972. The total cost of the Very Large Array was $78,578,000. At the time, this equaled roughly $1 per taxpayer.
The VLA is an interferometer; this means that it operates by multiplying the data from each pair of telescopes together to form interference patterns. The structure of those interference patterns, and how they change with time as the earth rotates, reflect the structure of radio sources on the sky: these patterns are taken and a mathematical technique called the Fourier Transform is used to make maps.
The VLA is used primarily by astronomers from around the world. It's also occasionally used for atmospheric/weather studies, satellite tracking, and other miscellaneous science.
