Observations with the continent-wide Very Long Baseline Array (VLBA) reveal previously unseen details in a jet of material ejected from the core of a galaxy seen as it was when the universe was only about 7 percent of its current age.

NRAO and GBO are saddened at the announcement of the decommissioning of the Arecibo Telescope in Puerto Rico, which has a long and distinguished history of scientific accomplishment.

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.
