these are spaces which are much colder than the surrounding places

Most black dots on the sun are sunspots, which are basically places in the sun's visible surface where the magnetic field of the sun pokes through. I don't know too much about stellar astrophysics, but sunspots are relatively cool compared to the rest of the sun's surface (not that hugely, though). The solar magnetic field goes through several cycles that paleoclimatologists (several that I know) are trying to track through changes in the earth's climate. Current theory states that these cycles are a result of the rotation and vibration of the sun (it does vibrate, much like a bell), but a lot of work is still being done on this subject.

Sunspots are areas of a magnetic storms on the suns surface. They are cooler than the surrounding surface so they appear black. Sunspots follow an 11 year cycle that is part of a 22 year cycle of magnetic reversal of the suns poles.

These black dots are large holes in the sun's plasma surface. They are called "sun spots". Large numbers of sun spots point to significant magnetic activity on the sun, and can often interfere with satellite signals.

Black dots on the sun as seen from earth are the passing of smaller planets before the sun in what is termed as an eclipse. Other dark patches on the sun - sun spots are caused by regeneration; the sun has a seven year cycle of refreshment. Odd huh, it burns but does not reduce in size nor get colder.

Hi, the black dots are called sun spots. They spots on the sun that are cooler then the surrounding areas.

Sunspots are areas in which the area around them is much colder than the rest of the sun.

Yes, even the Sun gets acne.

they r called sunspots.
sunspots-one of the relatively cool dark patches that appear in cycles on the Sun’s surface and possess a powerful magnetic field.

This an occurrence known as sunspots! Google It
