Revolutionary Discovery: Groundbreaking Findings on Magnetic Fields at the Center of Our Galaxy

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 at the center of the Milky Way. According to the European Southern Observatory, a new image from the Event Horizon Telescope (EHT) revealed for the first time in polarized light a ring of magnetic fields around Sagittarius A* black hole. These magnetic fields are similar to those observed around M87* black hole at the core of M87 galaxy, leading researchers to believe that strong magnetic fields may be common among all black holes.

Sara Issaoun, a member of Harvard’s Center for Astrophysics and co-lead of the project, explained that the new discovery shows the presence of strong, twisted and organized magnetic fields near the black hole at the heart of our galaxy. This was made possible through polarized light images which allowed astronomers to isolate the magnetic field lines of the black hole.

Supermassive black holes, found at the center of galaxies, are significantly larger in mass compared to our sun, with masses ranging from millions to billions of times greater. Although these entities emerged early in our universe, their origins remain a mystery due to their immense gravitational pull that makes it difficult to observe them directly. However, with EHT capturing images of M87* in 2019 and Sagittarius A* in 2022, astronomers were able to view halo of light that forms due to inflow and outflow matter and gas around black holes.

Angelo Ricarte, a member of Harvard Black Hole Initiative and co-lead on this project highlighted significance imaging polarized light emitted by hot gas surrounding black holes as it allowed researchers directly understand structure strength magnetic field that drive flow matter towards them . Mariafelicia De Laurentis , deputy scientist at EHT and professor at University Naples Federico II added presence strong magnetic field around both M87* and Sagittarius A* suggest universal fundamental characteristic these systems
