365telugu.com online news,October,3rd,2025:Scientists studying the supermassive black hole M87* — the very first black hole ever photographed — have made a striking discovery. Between 2017 and 2021, the black hole’s magnetic field completely reversed direction. This is the first time such a magnetic flip has ever been observed around a black hole.
The Magnetic Shift
When the Event Horizon Telescope (EHT) captured M87* in 2017, its magnetic field lines appeared to swirl in a clockwise direction. By 2018, researchers noticed the orientation starting to shift, and by 2021 the magnetic field had fully flipped, stabilizing in the opposite direction.
According to scientists, this shows that the plasma near the black hole’s event horizon is not static — it is dynamic and constantly evolving.
Why It Matters
M87* is not just famous for its iconic image; it also produces powerful jets of energy that stretch across space. These jets are believed to be powered and guided by the black hole’s magnetic fields. Understanding how these fields shift and evolve can provide vital clues about how such jets form and behave.

The Next Step
This finding marks an important step toward time-domain black hole astronomy — watching black holes change in real time. The EHT team is now preparing for a new round of observations in 2026, aiming to capture “movies” of M87* that will reveal how its magnetic fields and plasma evolve over time.
