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.
Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.

Hercules AThe Very Large Array sees fountains of hot gas erupting from a beastly black hole in the heart of a large galaxy known to radio astronomers as Hercules A. For millions of trillions of miles, these jets shoot through space, finally slowing when they reach ancient gaseous hiccups left behind by this galaxy’s earliest days of star-forming fury.
