Revealing the Magnetic Fields of Sagittarius A*: A Breakthrough Discovery by EHT.

Strong magnetic fields surround Milky Way’s black hole – Science & Tech.

Astronomers have recently made a groundbreaking discovery regarding powerful magnetic fields surrounding the black hole located at the center of our galaxy, the Milky Way. The European Southern Observatory announced that a new image from the Event Horizon Telescope (EHT) revealed, for the first time in polarized light, a ring of magnetic fields surrounding Sagittarius A*, the supermassive black hole at the heart of our galaxy. These magnetic fields are similar to those observed around M87*, the supermassive black hole at the core of the M87 Galaxy.

According to Sara Issaoun, a member of Harvard’s Center for Astrophysics and co-lead of the project, this new discovery shows that strong, twisted, and organized magnetic fields exist near Sagittarius A*. This was made possible through polarized light images that allowed astronomers to isolate the magnetic field lines of the black hole.

Supermassive black holes are significantly larger in mass compared to our sun and are found at the center of galaxies. Despite their immense gravitational pull, nothing can escape them directly. However, with EHT capturing images of M87* in 2019 and Sagittarius A* in 2022, researchers were able to view the halo of light that forms due to inflow and outflow of matter and gas around these entities.

Angelo Ricarte, another member of Harvard’s Black Hole Initiative and co-lead on this project, highlighted how imaging polarized light emitted by hot gas surrounding black holes is crucial in understanding their structure and strength. Mariafelicia De Laurentis, deputy scientist at EHT and professor at University Naples Federico II in Italy added that this finding suggests a universal characteristic among these systems.

In conclusion, this discovery marks an important milestone in understanding one of nature’s most mysterious phenomena: black holes. With further research into these cosmic giants we may gain insights into their origin and behavior that could revolutionize our understanding of gravity and even physics itself.
