The Karl G. Jansky Very Large Array ( VLA ) is a centimeter-wavelength radio astronomy observatory in the southwestern United States built in the 1970s. It lies in central New Mexico on the Plains of San Agustin , between the towns of Magdalena and Datil , approximately 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 .
51-464: San Marcial was a community in Socorro County , New Mexico , United States, founded in 1854 and survivor of two floods and a fire, but is now a ghost town , a deserted site with little left of the original town, destroyed in a great flood in 1929. San Marcial was approximately 25 miles (40 km) south of Socorro . San Marcial was founded circa 1854 by Pascual Joyla, who built a house on
102-517: A decade-long upgrade project resulted in the VLA expanding its technical capacities by factors of up to 8,000. The 1970s-era electronics were replaced with state-of-the-art equipment. To reflect this increased capacity, VLA officials asked for input from both the scientific community and the public in coming up with a new name for the array, and in January 2012 it was announced that the array would be renamed

With multiple mountain ranges, extents of grasslands and marshes providing a wide array of available habitats, Socorro County is home to an extensive variety of ecosystems and wildlife. Socorro County contains 826 species of wildlife, including 14 amphibians, 60 reptiles, 336 birds, and 96 mammals. Wildlife in
255-472: A total loss. From San Acacia to Lemitar, the water was spread out on both sides of the railroad three miles from bank to bank. With women and children safely out of town, men at San Marcial were fighting in the midst of crumbling structures in a last desperate effort to save their town from total destruction. Some residents tried to rebuild after the August 13 flood, but a second flood on September 23 put an end
306-450: A wye (or Y) -configuration, (each of which measures 21 kilometres (13 mi) long). Using the rail tracks that follow each of these arms—and that, at one point, intersect with U.S. Route 60 at a level crossing—and a specially designed lifting locomotive ("Hein's Trein"), the antennas can be physically relocated to a number of prepared positions, allowing aperture synthesis interferometry with up to 351 independent baselines: in essence,

This survey will cover the entire sky visible to the VLA (80% of the Earth's sky) in three full scans. Astronomers expect to find about 10 million new objects with the survey — four times more than what is presently known. The driving force for the development of

#1732788004993612-530: The National Radio Astronomy Observatory announced that they will be replacing the ageing antennae with 160 new ones at the site, plus 100 auxiliary antennae located across North America. The project, estimated to cost about $ 2 billion to build and around $ 90 million to run, will vastly expand the capabilities of the current installation and increase the frequency sensitivity from 50 GHz to over 100 GHz. The facility will be renamed

Orchards, alfalfa fields with other valley crops in this district as well as at Polvadero and Lemitar are reported

In 1989 the VLA was used to receive radio communications from the Voyager 2 spacecraft as it flew by Neptune . A search of the galaxies M31 and M32 was conducted in December 2014 through January 2015 with the intent of quickly searching trillions of systems for extremely powerful signals from advanced civilizations. It has been used to carry out several large surveys of radio sources, including

A self-guided walking tour is available, as the visitor center
867-638: The Apache Kid Wilderness. Stories of depredations by the Apache Kid, and of his demise, became so common and dramatic that in southwestern folklore they may be exceeded only by tales of lost Spanish gold. Native Americans lingered in the San Mateos well into the 1900s. We know this by an essay written by Aldo Leopold in 1919 where he documents stumbling upon the remains of a recently abandoned Indian hunting camp. A mining rush followed
918-506: The Apache wars – gold, silver, and copper were found in the mountains. It wasn't until this time that extensive use of the area by non-Native Americans occurred. While some mining activity, involving gold, silver, and copper, occurred in the southern part of the range near the end of the nineteenth century, the prospecting/mining remnants are barely visible today due to collapse, topographic screening, and vegetation regrowth. While miners combed

Congressional approval for the VLA project was given in August 1972, and construction began some six months later. The first antenna was put into place in September 1975 and the complex was formally inaugurated in 1980, after a total investment of US$ 78,500,000 (equivalent to $ 290,000,000 in 2023). It

There are four commonly used configurations, designated A (the largest) through D (the tightest, when all the dishes are within 600 metres (2,000 ft) of the center point). The observatory normally cycles through all the various possible configurations (including several hybrids) every 16 months;
