The video discusses the work of German astronomer Samuel Heinrich Schwab, who, like Galileo, was intrigued by sunspots. Over 17 years, Schwab observed a periodic cycle in the number of sunspots, discovering an 11-year solar cycle. This cycle is crucial for understanding space weather's impact on Earth, as it influences the frequency and intensity of solar storms.
