Magnetic fields detected around the black hole at the center of our galaxy

A recent study in Nature has confirmed that black hole M87 is spinning as previously theorised:

Scientists just proved that ‘monster’ black hole M87 is spinning — confirming Einstein’s relativity yet again

Astronomers have spotted two huge jets fired off by the 'monster' M87 black hole wobbling on an 11-year cycle, proving for the first time that black holes spin.

The discovery was made by studying powerful jets of energy beamed from the solar system-size black hole at the center of the neighboring Messier 87 galaxy.

"After the success of black hole imaging in this galaxy with the [Event Horizon Telescope (EHT)], whether this black hole is spinning or not has been a central concern among scientists," Kazuhiro Hada, an astronomer at the National Astronomical Observatory of Japan, said in a statement. "Now anticipation has turned into certainty. This monster black hole is indeed spinning."

How black hole jets acquire the enormous energy needed to do this has been a mystery, but physicists used Einstein's general theory of relativity to suggest the material could get it from the cosmic monsters' magnetic fields, if they were spinning rapidly on their axes.

By studying M87* using a global network of radio telescopes from 2000 to 2022, the astronomers found that the black hole's jets were ticking back and forth like metronomes marking out an 11-year cycle. This showed that the black hole was precessing or wobbling on its axis as it rotated, just like a spinning top.
