VLBI Network

Very Long Baseline Interferometry (VLBI) is a technique used in radio astronomy to measure the precise locations of celestial objects. It involves multiple radio telescopes located far apart on Earth, which simultaneously collect signals from a distant source, like a quasar. These signals are then combined to create a detailed image or gather data about the source. By comparing how the signals arrive at different telescopes, scientists can achieve remarkable accuracy in measuring distances in space. VLBI is crucial for understanding the universe, including studying black holes and the accuracy of global positioning systems.
