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.

NRAO Contest Winners Illustrate Diverse Cosmic Phenomena
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.
VLA Marks 40 Years at the Frontier of Science
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 Image Contest Celebrates VLA 40th Anniversary
To help celebrate the VLA’s 40th anniversary, the National Radio Astronomy is conducting an image contest, and offering cash prizes for visually compelling works that incorporate radio observational data from the VLA.
NRAO Science Continues Despite the Virus
Something done routinely for decades — move VLA antennas into a new configuration — suddenly became challenging because of COVID-19. With careful planning and a lot of teamwork, the NRAO staff got the job done to keep the scientific research going.
New Technologies, Strategies Expanding Search for Extraterrestrial Life
New technologies that enable new strategies are revitalizing the Search for Extraterrestrial Intelligence (SETI), by not only augmenting the traditional search for intelligently-generated radio signals but also allowing searches for other signs of life and technological activity.
