Taking a look at the Sun

In this composite image taken by the Solar Dynamics Observatory (SDO) on March 2nd, 2017 you can see the Sun in three different ways.

The first image is a magnetogram or magnetic image of the sun's surface, it shows where positive and negative particles are moving toward or away from strong magnetic areas. White and black areas indicate opposite magnetic polarities, with white showing north (outward) polarity and black showing south (inward) polarity.

The yellow image shows the surface in filtered light, and there the same active regions appear as dark, cooler splotches called sunspots.

The right image shows the Sun in extreme ultraviolet light ( at a wavelength of 171 angstroms, good for showing coronal loops ( - the arcs extending off of the Sun where plasma moves along magnetic field lines.

Take a look at even more views of the Sun here:
