The brightness variability of the Sun and other cool stars is one of the most exciting manifestations of the interaction between the matter and the magnetic field in their atmospheres. The recently achieved unprecedented precision of stellar brightness measurements as well as the progress in simulations of stellar atmospheres allows coming closer to understanding the origin of stellar magnetic activity and resulting brightness variations. Furthermore, stellar data allows constraining solar magnetic activity in the past and future as well as the resulting solar-terrestrial connection.
