Exploring the Very Large Array in New Mexico: A Window Into the Universe

Located on the vast plains of San Agustin in central New Mexico, the Very Large Array (VLA) stands as one of the most powerful and recognizable radio observatories in the world. Operated by the National Radio Astronomy Observatory (NRAO), the VLA has helped astronomers unlock countless secrets of the universe since it began operations in 1980.

What Is the Very Large Array?

The Very Large Array is composed of 27 massive radio antennas, each measuring 82 feet (25 meters) in diameter. These antennas work together as a single instrument through a process called interferometry, allowing the VLA to observe distant galaxies, black holes, quasars, and even the formation of stars with incredible precision. The antennas are arranged in a Y-shaped configuration and can be moved along 13 miles of railway tracks to change the array’s resolution and sensitivity.

A Place of Science and Discovery

The VLA has contributed to many groundbreaking discoveries in astronomy and astrophysics. It has mapped the structure of galaxies, studied pulsars, and provided detailed radio images of celestial phenomena invisible to optical telescopes. The site also gained public fame as a filming location for the 1997 movie Contact, starring Jodie Foster, which showcased its futuristic and awe-inspiring appearance.

Visiting the Very Large Array

The VLA Visitor Center, located about 50 miles west of Socorro, New Mexico, welcomes guests year-round. Visitors can explore the museum exhibits, view educational films, and take a self-guided walking tour to see the giant antennas up close. Guided tours are also offered on select weekends, providing deeper insight into how the VLA operates and what scientists are discovering there.

Best Time to Visit

The best time to visit the Very Large Array is during spring or fall when the weather in central New Mexico is mild and clear. The open desert setting provides stunning panoramic views of the surrounding landscape, making it an ideal spot for photography and stargazing.

Lodging and Nearby Attractions

The nearest city, Socorro, offers several hotels and motels for visitors, along with local dining options. While in the area, travelers can also visit Bosque del Apache National Wildlife Refuge, a beautiful stop for birdwatching, or explore the historic New Mexico Tech campus.

Why You Should Go

A trip to the Very Large Array is not just about seeing impressive technology—it’s about connecting with humanity’s quest to understand the cosmos. Whether you’re an astronomy enthusiast, photographer, or curious traveler, the VLA offers a unique and unforgettable experience deep in the heart of New Mexico.
