The Long Wavelength Array (LWA) is a radio telescope in central New Mexico.

[1] It is one of the few observatories to utilize relatively low frequencies (10-88 MHz), and is used to study relativistic particles, cosmic evolution, astrophysical plasma, decametric radio emissions from Jupiter-like extrasolar planets, and giant flares from magnetars.

with a total of 13,000 dipole antennas[3] strategically placed in an area nearly 400 kilometres (250 miles) in diameter, to scan the sky at HF and VHF frequencies.

[4] The first station, located adjacent to the NRAO's VLA, consists of 256 antennas and was completed in December 2009.

[5][needs update] The project is a collaboration of UNM, VT, LANL, JPL, NRL, UI, BIRS, NRAO and AFRL.
