Sun's hidden magnetic field mapped in 3D for first time
Scientists have mapped the Sun's outer magnetic field in 3D for the first time. Reports ask how researchers managed to reveal a field that is hard to see directly. It is a step forward in studying the star closest to Earth.
पार्श्वभूमीContext: The Sun's outer atmosphere, the corona, constantly releases a stream of charged particles called the solar wind, which can disturb satellites and power grids on Earth. Magnetic fields guide that flow, so mapping them helps space agencies forecast space weather.
