Unveiling the Magnetic Beauty of Sagittarius A*: EHT Reveals Stunning Spirals of Fields Around Milky Way’s Supermassive Black Hole

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

A group of researchers from various continents, led by the Event Horizon Telescope (EHT), have made a significant discovery regarding the magnetic fields around the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Milky Way galaxy. This research, published in two articles in The Astrophysical Journal Letters, reveals that powerful and organized spirals of magnetic fields emanate from the black hole.

In 2022, scientists unveiled the first image of Sgr A*, which despite being smaller and less massive than its counterpart in M87, showed striking similarities between them. To further investigate these similarities, researchers decided to study Sgr A* in polarized light.

The data collected suggests that the magnetic fields surrounding Sgr A* may enable it to launch powerful jets of material, similar to what was observed in M87. This discovery sheds light on the structure and strength of magnetic fields near black holes, providing valuable insights into their feeding and expulsion mechanisms.

While imaging black holes with polarized light presents challenges, this research indicates that strong magnetic fields may be a universal characteristic of all black holes. However, whether there is a jet around Sgr A* remains uncertain based on current observations.

The collaboration of telescopes around the world forming EHT played a crucial role in these groundbreaking observations, highlighting the importance of international cooperation in advancing our knowledge of the universe.

This discovery marks a significant milestone for astrophysicists worldwide and opens up new avenues for future research into these cosmic phenomena.
