Scientists Chart the Sun’s Subsurface Weather Tied to Its 11-Year Activity Cycle
An international team of solar physicists have traced giant tides of plasma beneath the Sun’s surface at a region called near-surface shear layer (NSSL). The plasma currents shift with the Sun’s magnetic heartbeat and could have far-reaching influence on space weather and Earth.
These findings give us a better understanding of how the Sun’s magnetic activity is linked to its internal flows and hint that we might still be missing something lurking in deeper layers that truly drives its global dynamics.
