It is difficult for astronomers to be sure that the rotation of the dark region represents the rotation of the dipole jets. Do they have any new plans?"In the new image, however, the brightest part of a ring surrounding the black hole has shifted counterclockwise by about 30°. That could be because of random churning in the disk of material that swirls around the black hole’s equator. It could also be associated with fluctuations in one of the jets launched from the black hole’s poles—a sign that the jet isn’t aligned with the black hole’s spin axis, but precesses around it like a wobbling top. That would be “kind of exciting,” Markoff says. “The only way to know is to keep taking pictures.”

It's interesting that the related images took 3-6 years to produce in the final version.
If the rotation of the darkening shows the rotation of the bipolar pole jets, the thing seems to have a very dynamic inner life
