Very Long Baseline Array

The Very Long Baseline Array is a system of ten radio telescopes which are operated remotely from their Array Operations Center located in Socorro, New Mexico, as a part of the National Radio Astronomy Observatory. These ten radio antennas work together as an array that forms the longest system in the world that uses very long baseline interferometry. The longest baseline available in this interferometer is about 8,611 kilometers.The construction of the VLBA began in February 1986 and it was completed in May 1993.
