 For much of history, humans have studied
the sky and the Sun. Ancient people built
structures like Stonehenge to observe the
Sun’s passage through the seasons.
 The
advent of the telescope in the 1600s allowed astronomers such
as Galileo Galilei
and Christopher Scheiner to
observe and sketch Sunspots. Solar flares were discovered in
1859 when Richard Carrington
focused his
telescope on  the Sun and saw
a bright flash on the projected image.
