Are there seasons on the Sun?
Experts have now found that even on the Sun there’s something comparable to the seasons. The intensity of solar storms increases to a maximum over a period of roughly eleven months and then decreases over the course of another eleven months. The reason for this phenomenon is magnetic fields that move to the surface of the Sun from its interior. Previously it was only known that solar activity occurs in a cycle that produces a particularly large number of sunspots every eleven years— a measure of high solar activity. The newly discovered two-year changes are similar to the change between rainy and dry seasons on Earth— just with a temperature of between 1.8 and 18 million degrees Fahrenheit.
