Coronal Loops

Coronal LoopsThe Atmospheric Imaging Assembly instrument aboard the Solar Dynamics Observatory images the solar atmosphere in 10 wavelengths every 10 seconds. Its data is used to link changes in the surface to interior changes in the Sun.In this image the Sun’s magnetic field can be readily visualized through bright strands called “coronal loops”. Loops are shown here in a blended overlay with the magnetic field measured by SDO’s Helioseismic and Magnetic Imager shown underneath. Blue and yellow represent the opposite polarities of the magnetic field.

    • I agree. Just when I think WJJH has posted the most beautiful image ever, he posts another one.
