"New Discovery Links Sun's Magnetic Field Origin to Improved Solar Storm Forecasts"

New research suggests that the sun's magnetic field, responsible for sunspots and solar flares, originates from a shallow region near its surface rather than deeper within. This discovery, made using NASA supercomputer simulations, could improve predictions of solar activity and geomagnetic storms. Interestingly, the study also found similarities between the sun's magnetic field generation and the plasma behavior around feeding black holes, challenging previous theories about the solar dynamo's deeper origins.
