VLBA antenna in Owens Valley, California

In northern California sits one of the identical ten antennas of the Very Long Baseline Array. Data from each of the 25-meter radio telescopes are shipped to the Array Operations Center in Socorro, New Mexico to be digitally combined. The ten antennas are spread over a 5,351-mile long baseline that runs from Hawai’i to St. Croix.
