The origin of the magnetic field covering the Sun has been discovered
Granada, Spain (SPX) Feb 20, 2015
The magnetic field that covers the Sun and determines its behavior -the eleven year cycles no less than such conspicuous phenomena as solar spots and solar storms- also has another side to it: a magnetic web that covers the entire surface of the Sun at rest and whose net magnetic flow is greater than that of the active areas. A study led by the Institute of Astrophysics of Andalusia (IAA-CSIC) has revealed where the flow that feeds this web comes from. The outline of the solar magnetic web coincid ... read more
