What are Sunspots? A History

Sunspots, to put it simply, are relatively cool areas on the surface of our star that are caused by the Sun’s magnetic activity.  But how did astronomers figure this out? How did their interpretations of sunspots change as the technology used in astronomical observation advanced? What ideas in astronomy and physics helped astronomers make sense of sunspots? Sunspots have been observed and recorded from well before the invention of the telescope through the centuries that followed.  We’ll explore the journey astronomers took to arrive at our current understanding of sunspots.
