Qué (quién) es VLA Very Large Array - definición
![The Bracewell Radio Sundial on the VLA walking tour, seen from the south. Named for [[Ronald N. Bracewell]], this sundial marks on the ground positions of the shadow of the central sphere (the [[gnomon]]) at different times of day and times of year. The shadow on Dec 22, 2017 falls very near the [[winter solstice]] line and the 1:00 PM (solar time) mark. The other two lines of markers north of the gnomon are for the [[equinox]]es and the [[summer solstice]]. Additional lines of markers south of the gnomon mark positions of "shadows" of the radio sources [[Cygnus A]] and [[Cassiopeia A]]. The posts at the back of the sundial were recovered from Bracewell's radio telescope array at [[Stanford University]], abandoned in 1980, where they had been signed by visitors with chisels at his invitation.](https://commons.wikimedia.org/wiki/Special:FilePath/Bracewell Sundial.jpg?width=200 "The Bracewell Radio Sundial on the VLA walking tour, seen from the south.

Wikipedia
The Karl G. Jansky Very Large Array (VLA) is a centimeter-wavelength radio astronomy observatory in the southwestern United States. It lies in central New Mexico on the Plains of San Agustin, between the towns of Magdalena and Datil, ~50 miles (80 km) west of Socorro. The VLA comprises twenty-eight 25-meter radio telescopes (twenty-seven of which are operational while one is always rotating through maintenance) deployed in a Y-shaped array and all the equipment, instrumentation, and computing power to function as an interferometer. Each of the massive telescopes is mounted on double parallel railroad tracks, so the radius and density of the array can be transformed to adjust the balance between its angular resolution and its surface brightness sensitivity. Astronomers using the VLA have made key observations of black holes and protoplanetary disks around young stars, discovered magnetic filaments and traced complex gas motions at the Milky Way's center, probed the Universe's cosmological parameters, and provided new knowledge about the physical mechanisms that produce radio emission.
The VLA stands at an elevation of 6,970 feet (2,120 m) above sea level. It is a component of the National Radio Astronomy Observatory (NRAO). The NRAO is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
