Quick Look: Spotted: 'Death Star' Black Holes in Action

Powerful beams blasting out of black holes can change directions over millions of years.
Astronomers used NASA’s Chandra and the NSF’s Very Long Baseline Array data to make this discovery.
They compared the beam’s directions in the past, using Chandra data, with the current directions using radio data.
This discovery shows the widespread impact black holes can have on their galaxy and beyond. The beams can prevent large numbers of stars from forming.
