The Very Large Array Telescope: The purpose and characteristics of the VLA

Radio astronomy has revolutionized our understanding of the universe, leading to the development of advanced instruments like the Very Large Array (VLA). Built by the National Radio Astronomy Observatory, the VLA is a powerful tool for studying various astronomical phenomena. Located in New Mexico, the VLA underwent significant upgrades to enhance its capabilities. It was renamed the Karl G. Jansky Very Large Array in honor of the scientist who discovered radio waves from the Milky Way. The VLA's antennas form a massive system that uses aperture synthesis to monitor unique light forms.
