Unveiling the Universal Nature of Black Holes: Groundbreaking Discovery of Magnetic Fields in Sagittarius A*

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

A team of researchers from around the world have made a groundbreaking discovery about the magnetic fields surrounding the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Milky Way galaxy. Using polarized light for the first time, they captured powerful and organized spirals of magnetic fields emanating from the black hole. These magnetic fields bear a striking resemblance to those observed in other galaxies, suggesting that strong magnetic fields may be a universal characteristic of black holes.

The research, published in two articles in The Astrophysical Journal Letters, involved over 300 scientists from various continents. They had previously unveiled the first image of Sgr A* in 2022, which showed similarities with another supermassive black hole in M87. To further investigate these similarities, they decided to study Sgr A* in polarized light.

The observations suggest that the magnetic fields surrounding Sgr A* may be enabling it to launch powerful jets of material, similar to what was observed in M87. This discovery provides valuable insights into the structure and strength of magnetic fields near black holes and their feeding and expulsion mechanisms. However, imaging black holes with polarized light presents challenges, and more research is needed to confirm this hypothesis.

Despite these challenges, the collaboration of telescopes around the world forming the Event Horizon Telescope (EHT) played a pivotal role in making this groundbreaking observation possible. This discovery highlights the importance of international cooperation in advancing our knowledge of the universe.

In conclusion, this discovery has opened up new avenues for future research on black holes and their magnetic fields, providing us with a deeper understanding of these mysterious cosmic phenomena.
