Magnetic Field Lines Galore
  
  The illustration maps the magnetic field lines emanating from the Sun and their interactions superimposed on an extreme ultraviolet image from SDO (Oct. 20, 2010). As one can see, the field lines are most dense around active regions, but they also link to other magnetically active areas across the Sun.
