What is true about sunspots
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
During a solar maximum, there are increased sunspots, solar flares, and coronal mass ejections. This leads to more solar activity, including geomagnetic storms on Earth and increased auroral activity near the poles. Solar maximum occurs approximately every 11 years as part of the solar cycle.
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
Sunspots were discovered in 1610 by Galileo.

It means to observe or conclude some thing about your experiment.
The observation that led Galileo to conclude that the sun rotated was when he looked through his telescope and noticed that their were sunspots on the sun. He later looked through the telescope once again and couldn't see the sunspots.
That Earth is not at the center of the universe - - radical thinking for his time.
Yes, Galileo observed sunspots through his telescope and made detailed observations of craters on the moon. These observations were significant as they supported the heliocentric model of the solar system and contradicted prevailing ideas about the nature of celestial bodies at the time.
Approximately 1,100 to 1,500 sun spots were recorded. See related link for a graph
