How the Sun's 11-Year Solar Cycle Works
The sun may be 93 million miles (149 million kilometers) away from Earth, but commotions on our nearest star have consequences much closer to home, which is why scientists have a keen interest in studying changes in the sun's activity.
The sun's temper varies on an 11-year cycle, typically taking about 5 1/2 years to move from the quieter period of solar minimum, to the more turbulent solar maximum.
One of the ways solar physicists monitor the solar cycle is by studying the surface of the sun for dark splotches called sunspots. These short-lived patches are caused by intense magnetic activity and tend to cluster in bands at mid-latitudes above and below the equator. The frequency and number of these mysterious dark spots on the solar surface act as indicators of the sun's activity as it moves between solar minimum and maximum. [Photos: Sunspots on Earth's Star]
