New research suggests the sun’s magnetic field originates just 20,000 miles beneath its surface, challenging previous estimates of 130,000 miles. Led by Geoffrey Vasil from the University of Edinburgh, the study offers insights into solar storms’ prediction. Solar flares and eruptions, driven by the sun’s intense magnetic energy, impact Earth’s power and communications systems. Despite advancements, understanding the sun remains incomplete. Published in Nature, the findings aim to unravel the solar dynamo process, crucial for predicting space weather.
