Hace 17 horas · New research indicates the sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the ones that slammed Earth earlier this month. The magnetic field appears to generate 20,000 miles (32,000 kilometers) beneath the sun’s surface. Previous calculations put the roots of this process more than ...
