Sunspots contain a strong magnetic field. Scientists believe that this magnetic field is generated by flows of plasma and gas deep below the surface of the sun, in the process called a dynamo. With Hinode, scientists discovered a new class of dynamo, referred to as a "chaotic dynamo" that is visible on the surface of the sun, called the photosphere.
