An object once thought to be a radio galaxy is actually an active black hole that changed angles to point directly at Earth, new research suggests.
In a distant galaxy, a supermassive black hole spewing radiation at near light speed has shifted its angle by a whopping 90 degrees to point directly toward Earth — a sharp turn that's puzzling physicists.
PBC J2333.9-2343, a large galaxy about 4 million light-years away, was previously classified as a radio galaxy, meaning its AGN's gargantuan jets of radiation were pointed perpendicular to our line of sight. But new research published March 20 in the journal Monthly Notices of the Royal Astronomical Society reclassifies the galaxy as a blazar, meaning the black hole's jets are now pointed directly at Earth.
