The Event Horizon Telescope (EHT) has released new observations of the supermassive black hole M87*, revealing unexpected changes in its magnetic field polarization and the ejection of powerful jets. Images from 2017-2021 show a complete reversal in the black hole's polarization, indicating a dynamic and complex environment near the event horizon. This challenges existing theoretical models and provides valuable insights into black hole physics, particularly the role of magnetic fields in matter accretion and energy ejection. The findings, soon to be published in Astronomy & Astrophysics, highlight the EHT's evolution as a key tool for understanding cosmic phenomena.
