THE SUN IS NEVER STILL

Spots are on the surface of the solar body where they are produced and also dissolved, some in shorter and others in longer periods. They are carried around the Sun; an important occurrence in itself.

Galileo Galilei 1611 AD

To the ancient Greeks the perfect nature of the Sun was an inviolate belief. All astronomical bodies were in the realm of the gods and, therefore, were unblemished by imperfections. The detection of sunspots on the Sun's surface was to destroy this belief and open up a fascinating world of a Sun which was both dynamic and volatile. In today's topic we will explore The Active Sun.
