Scientists confirm that the first black hole ever imaged is actually spinning::The first black hole humanity has ever imaged has also provided us with what researchers are calling "unequivocal evidence" that black holes spin.

The title kind of misses the point: of course it spins; it would be remarkable if it didn’t.

The really interesting bit is how relativistic frame dragging is causing its spin axis to precess.

(Also, the illustration conflicts with the description: it shows the whole accretion disk wobbling instead of just the jets.)

Can you ELI5 relativistic frame dragging and process?

Frame dragging is when matter drags spacetime along with it. Roughly think of a the wake of a boat disturbing other things in the water.

The misalignment of the black holes axis of spin, and the axis of the accretion disk is causing interesting frame dragging effects.
