New multi-wavelength observations mounted by the Event Horizon Telescope (EHT) collaboration across the entire electromagnetic spectrum have provided new insight into the impact of the black hole at the core of galaxy M87 on its immediate, and not so immediate, surroundings.

Astronomers using the VLA took advantage of the gravitational lensing provided by a distant cluster of galaxies to detect an even more-distant galaxy that probably is the faintest radio-emitting object ever found.

Astronomers using the VLA and VLBA have found the most distant cosmic jet yet discovered, material propelled at nearly the speed of light by a supermassive black hole in the core of a galaxy some 13 billion light-years from Earth.

New studies using the VLA and other telescopes have added to our knowledge of what happens when a black hole shreds a star, but also have raised new questions that astronomers must tackle.

When the Very Large Array was completed forty years ago, it was a different kind of radio telescope. Rather…

Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.

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.

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.
