NRAO has recently enhanced the capabilities of the Very Large Array (VLA) Radio Telescope. Find out more about this by visiting the VLA Expansion Project site.
In addition to new electronics in the antennas, a new correlator computer, known as WIDAR, was developed in a joint effort with Dominion Radio Astrophysical Observatory (DRAO).
