Exploring the Sun's influence on human culture and scientific thought, this overview traces the journey from ancient solar deities to contemporary solar physics. It highlights key figures like Anaxagoras, Eratosthenes, and Copernicus, who paved the way for modern understanding. The text delves into the development of solar observations, the discovery of the Sun's energy source, and the contributions of space missions to solar knowledge. Current challenges like the coronal heating problem and the faint young Sun paradox are also discussed.
