This dish in the Eastern Sierra off HWY 395 is part of the Very Long Baseline Array (VLBA), a series of ten giant dish antennas that work together as a single radio telescope, making it the world’s largest astronomical instrument. The dishes are located across the US, from the Virgin Islands to Hawaii. I photographed the antenna on Mauna Kea in 2001.

The VLBA is used by scientists to create high-resolution images of stars, galaxies, and other objects in space to study how stars and galaxies form and evolve.
