Sun May Be Moving Into Solar Cycle 25 Kicking Off A New Wave Of Activity
Our star generates a powerful magnetic field which goes through roughly 11-year-long cycles. At the end of this period, the polarity of this magnetic field flips, meaning that the north and south poles switch. Scientists refer to end of this cycle as a solar minimum, the period of lowest activity. The middle of the cycle—the solar maximum—on the other hand is a period of high activity. The last solar minimum took place in 2009....
