Sun's magnetic engine revealed deep beneath its surface
A study using data from the SOHO and GONG networks confirms the Sun's magnetic dynamo is generated near the tachocline, roughly 200,000 km (about 124,000 miles) below the Sun's visible surface, with rotating plasma bands tracing a butterfly pattern that aligns with the 11-year sunspot cycle. This supports tachocline-based dynamo models and could improve space-weather predictions, with findings published in Scientific Reports.
