Very Long Baseline Array
(radio interferometer stretching 8000 km)
The Very Long Baseline Array (VLBA)
is an interferometer consisting of 10 25 meter
radio telescopes spread across North America from
Hawaii to the Virgin Islands supporting a maximum
baseline of 5300 miles.
Its control room is in Socorro, New Mexico.
It observes wavelengths from 28 cm to 3 mm
in eight bands plus two narrow longer-wavelength
It is also used with additional radio telescopes
for longer baselines, known as the HSA (for High-Sensitivity Array).
This gives them angular resolutions
for the shorter wavelengths
as small as fractions of a milliarcsecond.
