The Very Large Telescope (VLT) is an array of four optical telescopes located at the Paranal Observatory in Chile. Operated by the European Southern Observatory (ESO), it is one of the most advanced ground-based telescopes in the world. Each telescope has a primary mirror measuring 8.2 meters in diameter, allowing astronomers to observe distant celestial objects with high precision. The VLT can work together to create a larger virtual telescope through a technique called interferometry. This capability enhances its ability to study various astronomical phenomena, including stars, galaxies, and exoplanets, contributing significantly to our understanding of the universe.
