These tours last 45 minutes and take visitors to areas behind-the-scenes at the VLA. Staff and VLA Volunteers are on hand to answer questions.

The First Saturday Tour event culminates in an evening of free Guided Night Sky Telescope Viewing at the Etscorn Observatory on the Campus of NM Tech located in Socorro. The night time event begins at dark and lasts two hours, despite weather conditions, no reservations required.

During the summer, our NRAO students provide tours on selected weekends. June 20 - August 15, 2015 the VLA will host Summer Student lead guided tours every Saturday at 11:00 & 1:00!   No reservations required.

What You Will See

VLAMoon1 small

The Visitor Center is open every day from 8:30 a.m. through sunset. As you enter, a sign will point you toward the theater, a good place to begin your tour. The 20-minute video presentation, produced in 2013 and narrated by Jodie Foster, provides an overview of radio astronomy, interferometry, and the VLA itself.

You will then want to explore our exhibits, to learn more about radio astronomy and the role the Very Large Array and other NRAO telescopes play in current research. A 5-minute silent video will show you how we move antennas.

Near the back door you will find a brochure to guide you on the walking tour that will take you to our Radio Sundial (download Radio Sundial brochure PDF), past our Whisper Dish Gallery, on to our Radio Astronomy Gallery, and finally to the base of one of the 230-ton working antenna on the array!

From there you will head toward the control building to climb up to the observation deck for a view of the array itself and details about the supercomputer processing taking place in the control building.

The walk returns you to the Visitor Center where you are welcome to browse through our gift shop to take home some souvenirs. The gift shop opens almost every day at 9:00 a.m. and closes at 4:00.

We suggest you make a right-hand turn as you leave the Visitor Center parking lot and head for the tall yellow building, following the signs for the AAB (Antenna Assembly Building) Tour. As you cross the railroad track there is a parking lot on your left. From there you may view our 28th antenna that may be undergoing routine maintenance. You will also (most of the time) get to see one of the transporters that is used to move the antennas.

You are welcome to take photographs of everything you see, but please keep your cell phone turned off or put in in airplane mode (otherwise it interferes with our observing).

Group Tours

For educational groups, we provide guided tours (if available!). We need at least three weeks' notice to arrange a guided tour. To arrange a guided tour for your education group, give our Education and Public Outreach office a call at (575) 835-7243 or fill out the Guided Tour Reservation form:

 Photography and Filming

As noted above, visitors to the VLA may photograph what they see from the designated self-guided walking tour. However, any filming or photography done by a commercial or professional entity, or that is done by anyone, amateur or professional, from areas not authorized for general-public tourists or outside the hours authorized for general-public tourists is considered to be "commercial." Such photography must be approved in advance, and requires completing an application process, coordinating with NRAO staff, and payment of fees. Full information on commercial photography and filming, along with the required application form, is provided below.
