Latest discovery of black holes, scientists reveal the evolution of polarized radiation near black holes over time.

Jin10 data reported on October 12, not long ago, multiple joint teams of the “Event Horizon Telescope” discovered new changes in the mysterious celestial body “black hole” in the universe. By comparing observational data taken in 2017, 2018, and 2021, scientists have made new important progress in revealing the variability of the black hole's magnetic field. In 2017, the magnetic field appeared to spiral in one direction, remained relatively stable in 2018, and then completely reversed by 2021. The evolution of polarization reflects the turbulent magnetic field around the black hole, which plays a key role in understanding how matter falls into the black hole and how the black hole releases energy outward.
