New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.

The Very Large Array Sky Survey (VLASS) is an ambitious project to make a high-resolution radio map of nearly…

ALMA telescope conducts largest survey yet of distant galaxies in the early universe

New radio images from ALMA show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter’s moon Io.

Join our host Melissa Hoffman as she talks about the history of the VLA and some of the remarkable objects it has discovered!

Winners in NRAO’s VLA 40th Anniversary Image Contest are from around the world, and their works illustrate a fascinating variety of celestial objects. Entries combined observational data from the VLA with data from optical, infrared, and X-ray telescopes, and from computer simulations.

The Very Large Array (VLA) turns 40 years old on October 10, and the National Radio Astronomy Observatory is hosting a day-long virtual celebration that day.

NRAO has joined DAPPER: a new NASA space mission to the far side of the Moon to investigate when the first stars began to form in the early universe.

Using the VLBA, astronomers have made the first direct geometric measurement of the distance to a magnetar. This precision measurement to one of the most magnetic objects in the Universe could help scientists determine if such objects are responsible for generating the mysterious Fast Radio Bursts.

Using ALMA, two teams of astronomers have for the first time discovered a planet-forming disk with misaligned rings around a triple star system, called GW Orionis.
