Unveiling the Magnetic Heart of the Milky Way: EHT’s Discovery in Sagittarius A* Reveals Striking Similarities with M87

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

Researchers at the Event Horizon Telescope (EHT) have made a groundbreaking discovery regarding the magnetic fields around the supermassive black hole Sagittarius A* (Sgr A*) at the center of the Milky Way. This discovery, captured in polarized light for the first time, reveals powerful and organized spirals of magnetic fields emanating from the black hole. The structure of these magnetic fields bears a striking resemblance to those observed around the black hole in the galaxy M87, hinting at the possibility of strong magnetic fields being common to all black holes.

The research involved over 300 researchers from various continents who had previously unveiled the first image of Sgr A* in 2022, which showed similarities between Sgr A* and M87 despite their differences in size and mass. To further investigate these similarities, researchers decided to study Sgr A* in polarized light.

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 sheds light on the structure and strength of magnetic fields near black holes, providing valuable insights into their feeding and expulsion mechanisms.

Imaging black holes with polarized light presents challenges due to their extremely dim and diffuse light output. However, data from observations indicates that strong magnetic fields may be a universal characteristic of black holes. While there is uncertainty about whether a jet exists around Sgr A*, its similarities with M87 raise intriguing possibilities for further research and understanding of these cosmic phenomena.

The collaboration of telescopes around the world forming EHT played a pivotal role in making these groundbreaking observations possible, highlighting the importance of international cooperation in advancing our knowledge of space science.

In conclusion, this discovery made by EHT researchers has opened up new avenues for understanding supermassive black holes’ behavior through studying their magnetic fields structure and strength. Further research could lead to more insights into how these cosmic phenomena work, ultimately leading to better comprehension of our universe’s nature.
