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.
VLA Sky Survey Reveals Newborn Jets in Distant Galaxies
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.
IMAGE RELEASE: A Galaxy’s Stop-and-Start Young Radio Jets
VLBA image shows details of a young jet emitted from the core of an active galaxy, revealing that the jet activity stopped, then restarted only a decade ago.

What does an active black hole look like? It depends on your point of view.
A Weakened Black Hole Allows its Galaxy to Awaken
Astronomers have found the first example of a galaxy cluster where large numbers of stars are being born at its core. The discovery revealed new details of how supermassive black holes affect their host galaxies.
Going Against the Flow Around a Supermassive Black Hole
At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used ALMA to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe.
