Is our sun going into hibernation?
Each sunspot cycle has been getting less intense. Is our star falling asleep? Solar activity refers to the state of the sun’s magnetic field and associated phenomena: sunspots, flares, solar wind and coronal ejections. During periods of minimal solar activity, such events are often uncommon and weak. During solar maximum, they’re at their strongest and most frequent. Magnetic field fluctuations on the sun can happen on drastically different timescales, ranging from seconds all the way to billions of years. When astronomers speak of a “slowdown” or a period of quiescence in the sun’s activity, it doesn’t mean the sun will stop shining, but that there’s a slowdown in activity. The sun has one particular rhythm, lasting approximately 11 years, in which its polar magnetic field flips polarity. Sunspots serve as an indicator of this change. Indeed, it’s often known as “the sunspot cycle.”
