Very Long Baseline Interferometry

Very Long Baseline Interferometry (VLBI) is a technique used in radio astronomy to improve the resolution of radio observations of celestial objects. It involves multiple radio telescopes located far apart, sometimes thousands of kilometers, which simultaneously observe the same astronomical source. By combining the signals collected from these telescopes, scientists can create an image with much finer detail than a single telescope could achieve alone. This method is crucial for studying distant galaxies, black holes, and other cosmic phenomena, allowing researchers to map the universe with impressive clarity.
