Decades of surface observations reveal our Sun’s mysterious magnetic interior
09 Mar, 2026 | Research & Innovation
Researchers at IIT Kanpur have achieved a major scientific breakthrough by mapping the magnetic field inside the Sun for the first time. By assimilating 30 years of solar surface observations from space satellites into a 3D computational model, the study reveals the magnitude, structure, and evolution of the Sun’s internal magnetic fields over three decades.
Led by Soumyadeep Chatterjee, PhD student, under the guidance of Prof. Gopal Hazra (Department of Physics, IIT Kanpur), the research—published in The Astrophysical Journal Letters—offers critical insights into the solar dynamo, the mechanism that drives the Sun’s 11-year magnetic cycle, sunspots, and solar eruptions.
This data-driven model not only deepens our understanding of solar magnetic activity but also improves predictions of future solar cycles, helping safeguard satellites, power grids, navigation, and communication systems from space-weather disruptions.
