The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It's the world's sharpest, dedicated telescope array.
The VLBA's super-sharp eye measures exact distances to quasars, plots MASERS in other galaxies, and sees black holes feeding.
The ten telescopes of the VLBA, stationed from Mauna Kea to St. Croix, use on-site technicians, a control team in New Mexico, and global users.
The recent upgrades to the VLBA include a new correlator and new receivers, designed and built by the NRAO.
