Magnetic field lines are denser in the active regions on the stellar surface.
The solar dynamics Observatory, NASA showed a picture of the Solar magnetic field on June 16 this year. The picture can be seen on the official website of the Department.
Magnetic field space object shown in the picture the white lines, which are denser in the active regions on the stellar surface. These pieces are magnetically intense areas on the surface of the Sun. The magnetic lines of more Alemannic regions, called coronal holes, outside lights.
Earlier NASA has demonstrated a unique poluchasovy video, which shows the Sun in Ultra HD format. The survey shows the activity of the stars, which is inaccessible for observation without special equipment.
