Discovery of slow waves on the sun could shed light on magnetic field mystery

3 min read



For the first time, scientists have observed giant slow-moving waves of plasma on the surface of the sun that could help to explain the mystery behind the star’s magnetic field.

Looking at ten years worth of data by NASA’s Solar Dynamic Observatory (SDO), researchers from the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen, both in Germany, detected plasma swirls spreading through the solar surface at the slow speed of just 3 mph (5km/h), about as fast as a human walks.
