The researchers from the University of Washington have resolved the myth behind the 11-year sunspot cycle and other mysterious properties of the sun by incenting a device that works on magnetic flux. The dark spots are generally seen on the surface of the sun, and remain on the surface for more than a week. And the reason why these patches on the sun appear was not known, but now researchers have explained the reason behind this phenomenon.

Scientists have worked on a model based on solar magnetic phenomena with respect to fusion energy. The model reveals a thin layer that is present beneath the sun’s surface, which is the key reason to many features we see from the earth which includes; sunspots, solar flow, and magnetic reversals.

The new model has a magnetic flux with free-floating electrons and plasma which move at different speeds on different parts ofthe surface of the sun. It is the difference in the speed between the flows that create a twist of magnetism which is known as helicity, which is similar to fusion reactor concepts. It is due to this twisting actions that lead to sunspots.

"Every 11 years, the sun grows this layer until it's too big to be stable, and then it sloughs off,"said Thomas JarboeUW professor of aeronautics and astronautics. The scientists are using this data to analyze the other hidden secrets on the sun’s surface.
