Discover the Very Large Array (VLA) Visitor Tour in New Mexico

Located in Socorro County, New Mexico, about 50 miles west of Socorro, the Very Large Array (VLA) Visitor Tour offers visitors a self-guided and ranger-supported experience at one of the world’s most iconic radio astronomy observatories. Set against the dramatic Plains of San Agustin, the site features 27 massive radio antennas arranged in a Y-shaped configuration across the desert landscape.

Guests can explore the visitor center, walk near the towering antennas, and learn how scientists use radio waves to study black holes, distant galaxies, and cosmic phenomena.

Why it’s special: The Very Large Array Visitor Tour provides rare public access to a working world-class radio astronomy facility featured in films and used in groundbreaking space research.

History & Story of the Very Large Array

Completed in 1980 and operated by the National Radio Astronomy Observatory (NRAO), the Karl G. Jansky Very Large Array was built to advance the study of the universe through radio astronomy. The facility’s 27 movable antennas work together as an interferometer, simulating a single giant telescope miles across.

Over the decades, the VLA has contributed to major astronomical discoveries, including research on black holes, pulsars, and deep space objects. Its unique design and remote desert setting make it one of New Mexico’s most scientifically significant landmarks.
