Magnetic Fields Surrounding Milky Way’s Black Hole – Exploring the Science & Technology

Unraveling the Enigma of Black Holes: Groundbreaking Discovery Reveals Strikingly Similar Magnetic Fields Surrounding Our Milky Way’s Sagittarius A* and M87 Galaxies

The European Southern Observatory recently announced a groundbreaking discovery made by the Event Horizon Telescope (EHT) – powerful magnetic fields swirling around the black hole located at the center of our Milky Way galaxy. This new image reveals a ring of magnetic fields surrounding the Sagittarius A* black hole in polarized light for the first time.

These magnetic fields are strikingly similar to those observed around the M87* black hole in the heart of the M87 Galaxy, leading scientists to believe that strong magnetic fields may be a common feature of all black holes. Sara Issaoun, who co-leads this project from Harvard’s Center for Astrophysics, described these magnetic fields near our Milky Way’s black hole as strong, twisted and organized.

The images captured in polarized light allow astronomers to isolate the magnetic field lines, providing insights into their structure and strength. Despite being one of the most massive objects in our universe, with masses millions and even billions of times greater than that of our Sun, supermassive black holes found at the centers of galaxies have remained a mystery to scientists until now.

However, thanks to advancements in technology, indirect observation has become possible through techniques such as imaging halo light produced by the flow of matter and gases attracted and expelled by these cosmic entities. The EHT captured this halo light emitted by Sagittarius A*, providing key insights into its behavior.

Angelo Ricarte from Harvard’s Black Hole Initiative was part of this project and explained that by imaging polarized light from hot glowing gas near black holes, scientists can directly infer structures and strengths of magnetic fields surrounding these cosmic entities. Mariafelicia De Laurentis from Italy’s National Institute for Astrophysics noted that observing these strong magnetic fields around both M87* and Sagittarius A* could be a universal and fundamental feature of these systems.

This discovery marks an exciting new chapter in understanding more about these mysterious objects at the center of galaxies.
