Radio days: VLBA turns on.
Radio astronomy will reach a milestone on Aug. 20 when the Very Long Baseline Array (VLBA), the world's largest astronomical instrument, begins formal operation. Featuring 10 receivers spread across 5,000 miles of U.S. territory and working as a single radio telescope, the VLBA has the ability to discern radio sources as small as the letters on this page from a distance of 3,000 miles. The network of telescopes has been under construction since 1986. Astronomers made their first observations with the completed system on May 29, when they examined a nearby star-forming region of our galaxy.
