Astronomers observe jet reorientation in 'Death Star' black holes

Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA's Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astronomical Observatory's (NRAO) Very Long Baseline Array (VLBA), shows what kind of widespread impact black holes can have on their surrounding galaxy and beyond.
