The U.S. National Science Foundation (NSF), the NSF National Radio Astronomy Observatory (NSF NRAO), and the U.S. Naval Observatory (USNO) are advancing a new collaboration to support the future of high-resolution radio astronomy and astrometry, with the development of a pathfinder instrument for the proposed Next Generation Very Large Array (ngVLA).

A team of astronomers led by Juan D. Soler of the University of Vienna used the NSF VLA, operated by the U.S. National Science Foundation’s National Radio Astronomy Observatories (NSF NRAO), to obtain high-resolution observations of the emission from neutral hydrogen atoms (HI) at 21 centimeters wavelength

Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA), together with the NASA James Webb Space Telescope and other observatories, have identified an enormous, galaxy-scale stream of super-heated gas erupting from the nearby galaxy VV 340a.

Astronomers using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments, the U.S. National Science Foundation Very Large Array (NSF VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), have revealed a dense cocoon of gas around one of the most extreme cosmic explosions ever seen, showing that a ravenous black hole ripped apart a massive star and then lit up its surroundings with powerful X-rays.
