"South Korean Research Team Discovers Spinning Black Hole"

Scientists have observed a wobble in the jet of material being flung out from the center of the galaxy Messier 87, providing evidence that its supermassive black hole is spinning. By examining 22 years of data, researchers found that the innermost portion of the jet twirls around once every 11 years, indicating the rotation of the black hole. The wobbling of the accretion disk, which is connected to the jet, suggests that the plane of its spin is not entirely aligned with the black hole's spin. This finding sheds light on the growth and history of supermassive black holes.
