Why the Sun appears completely without patches?

Often people interested in astronomy, and everything from delicate and complex details. Many wonders. Why the Sun appears completely without spots in photos?! So, a team of scholars of India and the United States because of the emergence of the Sun in astronomical images stains is a specific combination of what looks like a Dynamo.

The scientists explained in their study published in the scientific journal "nature" these spots reflecting minimal activity since about 100 of Sun with a session of hot gas is electrically charged plasma "," moving from North to South. Solar activity fluctuates in time nearly 10 years. Sunspot is among the evidence of this activity produces these patches because of magnetic fields in the Sun and that the coherence of these electrically charged plasma. This leads to hot gas cooling slightly making it appear darker than the surrounding cover.

And I got the last solar cycle which was given no. 23 peak in 2001 and then record the highest number of astronomers days in the Sun without the patches since the start of the limitation in modern astronomy. This was a clear decline in the activity of the Sun, meanwhile, resumed activity sun rise. For information on the reason behind the decline in the activity of the Sun, researchers under the auspices of the dibindo Nandi emulates more than 210 solar activity cycles using computer relying on mainly on the plasma electrically charged solar cycle which generate magnetic fields similar to areas of Dynamo.

This shows a simulation course fast North South of solar plasma in the first half of the activity of the Sun, followed by a slower phase in the second half, leading to a minimum of sunspot. Scientists said that although the decline observed in the solar cycle has not been physically but not individual case where this pace can recur in future Sun activity.

Scientists stressed the importance of this information to predict the so-called space weather because the activity of the Sun affect the Earth. The Sun's activity fluctuations not only radiation intensity fluctuations but also the recurrence of gas which produces large plasma pull shot in space. If I got such a "solar storm" one of the consequences could be disrupted satellites and electrical networks as well as shell stop wireless communications and air traffic stopped.
