Twenty-seven radio telescopes, each 82 feet in diameter, stand in the New Mexico desert on railroad tracks that let them move. Arranged in a Y-pattern across the Plains of San Agustin, the Very Large Array works as a single instrument, combining signals from all 27 antennas to simulate one telescope 22 miles across. The VLA sees what optical telescopes cannot: radio waves from the coldest and most distant objects in the universe, from black holes and quasars, from the cosmic microwave background radiation that permeates everything. The antennas look like set dressing for a science fiction film - and they've appeared in several. But they're real, doing real science, listening to a universe that speaks in frequencies humans cannot hear.

Radio astronomy detects electromagnetic radiation at wavelengths longer than visible light. Objects that appear dark optically - cold gas clouds, cosmic dust, the space between galaxies - emit radio waves. The VLA observes black holes, star-forming regions, and distant galaxies. ...

The 27 antennas work together through interferometry - combining signals from multiple telescopes to create resolution equivalent to one enormous dish. The VLA can reconfigure, moving antennas along 40 miles of double-track railroad. The most compact configuration spans 0.6 miles...

The Plains of San Agustin provide ideal conditions: 7,000 feet elevation, minimal radio interference from human sources, excellent atmospheric transparency. The basin is surrounded by mountains that block radio noise from distant cities. The dry climate reduces interference from ...

The VLA became culturally iconic through film appearances: 'Contact,' 'Transformers,' '2010,' and numerous documentaries. The visuals are irresistible - gleaming white dishes against blue sky, mechanical ballet of synchronized pointing, the obvious seriousness of the enterprise. ...

The VLA is located on the Plains of San Agustin, roughly 50 miles west of Socorro, New Mexico via US-60. The visitor center is open daily; admission is free. Self-guided walking tours reach the base of an antenna. The gift shop is excellent. Guided tours run monthly on selected S...
