Physicists Trace Sun's Magnetic Engine, 200k Kilometers Below Surface

NJIT physicists analyzed nearly 30 years of solar acoustic data and identified the solar dynamo — the Sun's magnetic engine driving its 11-year cycle — operating roughly 200,000 kilometers below the surface. By combining observations from NASA's SOHO, SDO, and the ground-based GONG network, they created one of the longest records of the Sun's internal vibrations, providing the clearest observational evidence yet of where the star's magnetic fields originate.
