The magnetic field around the black hole enables it to launch powerful jets of material into space, researchers say
Astronomers on Wednesday announced that they have detected a strong and organized magnetic field twisted in a spiral pattern around the Milky Way’s supermassive black hole, revealing previously unknown qualities of the immensely powerful object lurking at the center of our galaxy.
The researchers released a new image showing the environment around Sgr A* in polarized light for the first time, revealing the magnetic field structure. The polarized light comes from subatomic particles called electrons gyrating around magnetic field lines. “This new image, along with a strikingly similar polarization structure seen in the much larger and more powerful M87* black hole, shows that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them,” Issaoun added.
The new image, like the previous images of Sgr A* and the M87 black hole, was obtained using the Event Horizon Telescope international scientific collaboration’s global network of observatories working collectively to observe radio sources associated with black holes.
