Event Horizon Telescope researchers have captured unprecedented views of magnetic turbulence near the supermassive black hole M87* in the galaxy M87. While the black hole’s shadow remains stable, its surrounding magnetized plasma exhibits dramatic shifts in polarization patterns, challenging existing astrophysical models.

The 2017 and 2021 observations revealed a reversal in magnetic field orientation, suggesting a dynamic, churning environment close to the event horizon. These findings, published in *Astronomy and Astrophysics*, highlight the complexity of magnetic fields shaping black hole behavior and jet formation.
