This radio telescope is part of the Very Long Baseline Array, a network of ten telescopes throughout the United States that can make observations at very short wavelengths (approximately in the range of 3 millimeters to 900 millimeters). It's right next to the Owens Valley Radio Observatory run by Caltech, which consists of about a dozen radio telescopes of various sizes.
When I took this picture I was careful to frame it so I'd include the mountains in the background. However, it wasn't until I got home that I realized just how striking those mountains were. If you told me this picture was taken in the high Andes I think I'd believe you.

The Owens Valley is a remarkable place. Not as appreciated as it should be.
Just rewatched Contact. What a coincidence.
I wonder what is happening with the antenna in Arecibo, Puerto Rico.
Probably, slowly removing what is left. It's a shame, but the arrays and the orbitals fill the bill.
I think you mean LONG wavelengths. Short wavelengths are x-rays and gamma rays. The VLA works in the radio frequencies. Big dishes are needed for long wavelengths.
He means very-short-wavelength radio.
