The World's Largest Radio Telescope† The Very Large Array (VLA) radio telescope on the Plains of San Augustin, 50 mi. west of Socorro,
New Mexico. Dedicated Oct. 1980, it remains the premier astronomical instrument in the world for radio astronomy.

VLA vs. EVLA:
VLA construction began in 1975; I began working here in 1977; the VLA was completed and dedicated in
October 1980. It has operated 24/7 ever since. In 2010, the Expanded VLA (EVLA) was completed. Virtually all of
the VLA electronics was redesigned and rebuilt with current technology for greater sensitivity, wider IF bandwidths, and replacing
the old circular waveguide with fiber optics. This included new receivers, new feedhorns, new up- and down-converters, and
a new correlator.
