The VLA will get a new system allowing it to continuously monitor the sky to study the ionosphere and detect short bursts of radio emission from astronomical objects.

VLBI between West Virginia and Shanghai and the world’s first radio sundial.

Astronomers studying gas halos around nearby galaxies were surprised Very Large Array showed that one of their subjects is not a single galaxy, but two, superimposed on the sky to masquerade as one.

Doom may be averted for the Smith Cloud, a gigantic streamer of hydrogen gas that is on a collision course with the Milky Way Galaxy.

Academy Award-winning actress Jodie Foster narrates our new VLA Visitor Film.

Astronomers using a worldwide network of radio telescopes have found strong evidence that a powerful jet of material propelled to nearly light speed by a galaxy’s central black hole is blowing massive amounts of gas out of the galaxy.

Astronomers have made an important measurement of the magnetic field emanating from a swirling disk of material surrounding the black hole at the center of our Milky Way Galaxy.

Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Very Large Array, astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies.

Astronomers using a world-wide collection of telescopes have discovered the most prolific star factory in the Universe, surprisingly in a galaxy so distant that they see as it was when the Universe was only six percent of its current age.

The record-setting close approach of an asteroid on February 15 is an exciting opportunity for scientists, and a research team will use National Radio Astronomy Observatory and NASA telescopes to gain a key clue that will help them predict the future path of this nearby cosmic neighbor.
