VLBA: Owens Valley
By Jack Freer | Posted March 23, 2013 | Big Pine, California
The Very Long Baseline Array (VLBA) is a system of 10 radio-telescope antennas, controlled remotely from the Array Operations Center in Socorro, New Mexico by the National Radio Astronomy Observatory. Each station has a dish 82 feet (25 meters) in diameter and weighing 240 tons and is nearly as tall as a 10-story building when pointed straight up.
From Mauna Kea on the Big Island of Hawaii to St. Croix in the U.S. Virgin Islands, the VLBA spans more than 5,000 miles, providing astronomers with the sharpest vision of any telescope on Earth or in space. Dedicated in 1993, the VLBA has an ability to see fine detail equivalent to being able to stand in New York and read a newspaper in Los Angeles.
