Event Horizon Telescope Unveils Dynamic Magnetic Flips Around Black Hole M87* Over Four Years
  • These images show that the polarization of plasma near M87* flipped direction between 2017 and 2021, while the size of the black hole's shadow remained consistent, supporting Einstein's general relativity but indicating complex magnetic activity.

  • These findings deepen our understanding of the complex magnetic and energetic processes near supermassive black holes, with significant implications for astrophysics and black hole physics.

  • Researchers from the Center for Astrophysics at Harvard & Smithsonian confirmed through synthetic data tests that the observed polarization shifts are genuine and not artifacts of data analysis.

  • Advancements in imaging, including new telescopes like Kitt Peak and NOEMA, have improved the resolution and sensitivity of EHT observations, enabling more detailed studies of black hole physics.

  • The reversal in polarization suggests turbulence and evolving magnetic structures in the plasma, which could influence how the black hole accretes matter and interacts with its environment.

  • The latest data also detected signatures of extended jet emission near the jet base connected to the ring around M87*, offering new insights into matter and energy behavior in extreme gravitational environments.

  • Images captured the base of a near-light-speed jet emanating from the black hole, shedding light on how supermassive black holes influence their host galaxies through energetic jets.

  • Ongoing upgrades to the EHT network promise even clearer images in the future, which will enhance our understanding of black hole dynamics, plasma behavior, and their role in cosmic evolution.

  • Recent images from the Event Horizon Telescope (EHT) have revealed a highly dynamic environment around the supermassive black hole M87*, with notable changes in magnetic field polarization patterns over four years.

  • Initial observations in 2017 showed magnetic fields spiraling in one direction, but by 2018 they stabilized, and by 2021, they reversed, indicating continuous evolution of the black hole’s environment.
