Title:
The Very Large Array Turns Twenty
Explanation:
The most photogenic array of radio telescopes [ http://csep10.phys.…] in the world has also been one of the most productive. Each of the 27 radio telescopes [ http://www.r-clarke…] in the Very Large Array [ http://info.aoc.nra…] (VLA) is the size of a house [ http://www.msue.msu…] and can be moved on train tracks. The VLA [ http://antwrp.gsfc.…], celebrating its twentieth year [ http://www.aoc.nrao…] of operation, is pictured above [ http://www.aoc.nrao…] in a compact formation in front of Tres Montosas [ http://angeleschapt…], New Mexico [ http://www.state.nm…], USA [ http://www.odci.gov…]. The VLA [ http://info.aoc.nra…] has been used to discover water on planet Mercury [ http://www.aoc.nrao…], radio-bright coronae around ordinary stars [ http://www.aoc.nrao…], micro-quasars in our Galaxy [ http://www.aoc.nrao…], gravitationally-indu ced Einstein rings around distant galaxies [ http://www.aoc.nrao…], and radio counterparts to cosmologically distant gamma-ray bursts [ http://www.aoc.nrao…]. The vast size of the VLA [ http://antwrp.gsfc.…] has allowed astronomers to study the details of super-fast cosmic jets [ http://www.aoc.nrao…], and even map the center of our Galaxy [ http://www.aoc.nrao…]. An upgrade of the VLA [ http://www.aoc.nrao…] is being planned [ http://info.aoc.nra…].
