Magnetic Spirals Wrap Around the Milky Way's Central Black Hole
Deep within the crowded, dust-shrouded core of the Milky Way, some 27,000 light-years from Earth, lies a dormant beast. Sagittarius A*, the supermassive black hole anchoring our galaxy, has long been characterized as a quiet giant, consuming only a trickle of matter compared to its hyperactive peers in distant galaxies. Yet, beneath this deceptively calm exterior, a highly organized and powerful physical engine has been revealed. For the first time, astronomers have mapped the intense, polarized magnetic fields twisting around the very edge of Sagittarius A*'s event horizon. This breakthrough observation reveals a striking, coherent spiral pattern of magnetic force lines weaving through the superheated plasma swirling around the black hole. The discovery suggests that strong, highly ordered magnetic fields are not unique to active, jet-spewing galactic nuclei, but may instead be a universal feature of all supermassive...
