Revolutionary Discovery: Scientists Uncover Organized Spirals of Magnetic Fields Around Sagittarius A* at the Center of Our Milky Way”.

New view of the magnetic fields surrounding the black hole in the Milky Way

Scientists at the Event Horizon Telescope (EHT) have made a remarkable discovery regarding the magnetic fields around the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Milky Way galaxy. The researchers captured these magnetic fields in polarized light for the first time, revealing organized spirals emanating from the black hole.

These findings, published in two articles in The Astrophysical Journal Letters, were made possible by the collaboration of over 300 researchers from various continents. Previously, scientists had unveiled the first image of Sgr A* in 2022, which showed striking similarities with those observed in other black holes, including M87. To further investigate these similarities, researchers decided to study Sgr A* in polarized light.

The observations suggest that strong magnetic fields may be enabling Sgr A* to launch powerful jets of material, as seen in M87. This discovery provides valuable insights into the structure and strength of magnetic fields near black holes, shedding light on their feeding and expulsion mechanisms.

However, imaging black holes with polarized light presents challenges due to their extreme luminosity and energy output. Nevertheless, this data hints at a universal characteristic of black holes: strong magnetic fields may be present around all such objects.

While evidence for a jet around Sgr A* remains uncertain due to its relatively smaller size compared to M87’s jet, the similarities between these two black holes raise intriguing possibilities for further research into cosmic phenomena. The international collaboration of telescopes forming EHT played a pivotal role in these groundbreaking observations, emphasizing the importance of international cooperation in advancing our knowledge of the universe.

Overall, this discovery marks a significant step forward in our understanding of supermassive black holes and their surrounding environments.
