The supersharp radio “vision” of the National Science Foundation’s Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth.
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.
The National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are saddened by the announcement of the decommissioning of the Arecibo Telescope in Puerto Rico due to recent and devastating structural damage.
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.
