In the middle of the 16th century, shortly after the invention of the spyglass, which is a cylindrical object that serves to increase objects which are at a great distance, it became possible to begin observing the Sun. After several observations, people began to notice that dark spots appeared and disappeared on the surface of it.

And so were created several speculations about what they could be.
Sunspots are part of the phenomenon where dots end up appearing on the surface of the Sun and remain for an indefinite period of time. What everyone wants to know is, after all, what are these stains and why do they appear? They are regions where the surface temperature is reduced, as there is a presence of intense magnetic fields that thus inhibit the convective process of the surface.
This, in turn, decreases the flow of energy existing inside the star, which leaves a lower temperature in these regions.
Sunspots are currently taking up much of the time and study of many specialists. This is because most solar flares and coronal mass ejections end up being related to them. The flares and mass ejections arise in magnetically active regions, near clusters of nearby sunspots.
Therefore, what is concluded at the moment is that the greater the number of visible spots, the greater the number of eruptions and solar storms driven by coronal mass ejections.
Other consequences caused by these phenomena are the problems generated in telecommunications satellites, electrical discharges in transmission lines, interruption of energy supply and also an increase in the level of radiation that reaches the astronauts. This can cause various changes in the cells of the body.
It is no surprise that monitoring of sunspots has become extremely important. It is also essential to mention that it is necessary to be very careful when observing the Sun, because for that you need some specific equipment, such as telescopes and spyglasses. If the observation is not done correctly, solar radiation can cause irreversible damage to the vision of those who do not take the necessary precautions.
