Very-long-baseline interferometry - Wikipedia
Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. In VLBI a signal from an astronomical radio source, such as a quasar, is collected at multiple radio telescopes on Earth or in space.
Very Long Baseline Interferometry - Center for Astrophysics
Using a technique known as very long baseline interferometry (VLBI), researchers link observations from radio telescopes separated by whole continents into one virtual observatory. VLBI allows high-resolution radio light observations of the centers of galaxies and other regions of space difficult to observe with single telescopes.
