The Milky Way’s black hole is constantly bubbling

New James Webb Space Telescope observations show ongoing activity around Sagittarius A*, our galaxy's central supermassive black hole. Its plasma disk exhibits constant "bubbling" that changes rapidly, likely due to turbulence. Intense flares occur randomly several times daily, possibly from magnetic reconnection events. These year-long observations confirm previous predictions about disk variability and offer new insights into galactic center processes.
