Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th century, the Italian astronomer Galileo Galilei was the first to routinely observe sunspots. In the 20th century, with the help of modern techniques such as spectroscopy and later polarimetry, scientists realized that these spots are the locations of strong magnetic fields.
