The SunGranules – light and dark areas of
photosphere: when magnified looks like sand grains
(results from Hot gases rising and cooler gasses sinking)

The SunSunspots are caused by magnetic
effects resulting from the equator of the sun rotating faster than the poles.

The SunSunspot cycle – increases and
decreases on a __11__ year cycle.Average sunspot is about the size of
the earth.

The SunGalileo was first to observe
sunspots and went blind because of the sun’s harmful radiation waves.

The SunCorona – The outer most layer of the
sun (2 million °C) can only be seen during a solar eclipse.
