New research places the sun's magnetic field close to the surface, upending decades of theories
Researchers from Northwestern University have discovered that the sun’s magnetic field originates close to the surface, instead of deep inside the sphere. This could improve solar forecasts in the future.
During the strongest part of this cycle, powerful winds and sunspots form at the solar equator, along with plumes of material that cause the aurora borealis here on Earth. It would also lead a coronal mass ejection to bump up against Earth’s magnetic field, which would shut down power grids, cell phone satellites, modern cars and even airplanes. “We still don’t understand the sun well enough to make accurate predictions” of solar weather, lead study author Geoffrey Vasil of the University of Edinburgh told The Hill.
