Astronomers have published new images of a bright jet of material, long enough to cross the Milky Way three times, fired into space by the black hole at the heart of a distant galaxy.
The observations confirm the existence of a second jet, blasting in the opposite direction.
The study uses this galaxy, Pictor A, to test ideas about what makes jets like these emit very bright X-rays.
