The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is thrilled to invite the public to the NSF Very Large Array (NSF VLA) Fall Open House on Saturday, October 12, 2024, from 9:00 am to 4:00 pm.

An international team of astronomers has demonstrated that this persistent radiation originates from a plasma bubble, shedding new light on the enigmatic sources powering these cosmic phenomena.

A team of astronomers has found a new tool to discover pulsars. Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds.

Huge black holes are firing powerful beams of particles into space — and then changing their aim to fire at new targets.

NRAO and SpaceX have engaged in coordinated experiments involving NRAO telescopes and the Starlink satellite constellation for over two years. Early experiments began in late 2021 with the deployment of working Starlink user terminals near the Jansky Very Large Array (VLA) in New Mexico and have continued to the present day. These experiments highlight the ways in which satellite constellations and radio telescopes might be able to coexist, provided there is mutual awareness of what the other is doing.

Looking for a more efficient way to process a particularly large VLA data set, to produce one of the deepest radio images of the Hubble Ultra Deep Field (HUDF), made famous by the Hubble Telescope, NRAO staff decided to try a different approach.

Over the course of two scientific meetings, held in 2022 and 2023, German astronomers have collected 41 highly compelling science cases involving 57 unique authors from 19 German institutions, all aspiring to use the ngVLA.
