Astronomers observing the supermassive black hole M87* have discovered unexpected changes in its magnetic field polarization over several years, indicating a complex and dynamic magnetic environment near the event horizon, challenging existing models and highlighting the evolving capabilities of the Event Horizon Telescope.
Astronomers are using AI to analyze previously discarded data from the Event Horizon Telescope, leading to new insights into the structure and rotation of the supermassive black hole Sagittarius A* at the center of the Milky Way, including evidence that it spins at nearly top speed.
A study using the Event Horizon Telescope reveals that black hole jets are more complex than previously thought, showing signs of acceleration and brightness increases that challenge traditional models, with future research aiming to uncover the underlying mechanisms.
