Which European observer is credited with scientifically documenting solar rotation in the early 17th century using charting of sunspots?
Answer
Galileo Galilei
While ancient Chinese records alluded to solar activity, the formal, scientific documentation proving the Sun's rotation is credited to European observers in the early 17th century. Galileo Galilei is specifically recognized for his meticulous charting of sunspots over extended periods. By observing the consistent, predictable movement of these temporary surface features as they traversed the solar disk from the eastern limb to the western limb, he established concrete observational proof that the Sun was a dynamic, spinning body, not a static sphere.
