Black hole's jet shifts towards Earth in unprecedented cosmic event.

Astronomers have observed a jet streaming from the core of a distant galaxy that has changed directions, marking the first time they have observed a galaxy in the former group transform into a blazar. The galaxy, named PBC J2333.9-2343, is located about 656 million light-years away from Earth and is classified as a radio galaxy. The jet's orientation has changed by 90 degrees, now facing Earth, and astronomers suspect that the galaxy is X-shaped. The research is described in a paper published in the Monthly Notices of the Royal Astronomical Society.
