Astronomers studying a rare stellar explosion first spotted as a brief burst of X-rays used radio observations to help show that the dying star did not produce the powerful jet often associated with gamma-ray bursts.

CANCELED: NSF VLA Open House, Sat. Oct. 10th, 2026
The annual Fall Open House on Saturday, October 10, 2026, from 9:00 a.m. to 4:00 p.m has been cancelled due to road closures from recent flooding.
NSF VLA Sky Survey Sets New Standard for High-Resolution, Wide-Area Radio Astronomy
The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) has completed observations for the Very Large Array Sky Survey (VLASS), the most detailed radio survey of the sky ever conducted, providing an unprecedented view of the dynamic radio universe.
NSF VLA Maps a Hidden Hydrogen Shell Around the Orion Nebula
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
Hidden Jet from a “Missing-Link” Black Hole Lights Up the Radio Sky
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermediate-mass black hole tears apart a star, revealing what appears to be the off-axis afterglow of a powerful jet.
NSF VLA and ALMA Reveal Hidden “Ring Factories” of Giant Star Clusters in Nearby Galaxies
Astronomers have used U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) radio telescopes in Chile and New Mexico to peer through cosmic smoke and haze, building one of the clearest pictures yet of how giant clusters of young stars are born in the hearts of nearby galaxies.
