The sun has spots. Here’s what we’ve learned about them so far.

Of all of the features associated with our sun, sunspots are by far the most conspicuous. 

Long before the invention of the telescope, the Chinese Chronicles recorded numerous sightings of dark areas on the face of the sun, apparently seen when the sun’s light was significantly dimmed by clouds and haze, especially around sunrise or sunset. The Chinese often referred to these dark areas as “flying birds.”
