"A team of international astronomers have reclassified a galaxy after finding that a supermassive black hole in its centre has changed direction and is now aiming towards the Earth. The galaxy in question is found 657 million light-years away from us and goes by the name of PBC J2333.9-2343.

"We started to study this galaxy as it showed peculiar properties. Our hypothesis was that the relativistic jet of its supermassive black hole had changed its direction, and to confirm that idea we had to carry out a lot of observations," said Dr Lorena Hernandez-Garcia, according to the Royal Astronomical Society (RAS)."
