Sunspot on the Sun

Sunspot on the Sun, originally uploaded by powersdale.

By projecting the light from the telescope on a piece of paper, an image of the sun appears on the paper. I am pointing to a sun spot.

Because the Sun rotates around its axis in 26 days, these sun spots move across the face of the sun. Sun spots are storms on the sun. They start out small, grow in size, and then dissipate similar to storms on the earth. Sometimes the sun spot can disappear from view, rotate around the back side of the sun and then come back into view before it dissipates.
