Passage 2
It seems to shine unchangingly, pouring out a constant light year after year. But the sun may not be nearly so stable as we suppose. It is now thought to move quickly and irregularly and change in long-term cycles, growing dimmer and then brighter with each passing year. Some even fear that its frequent changing behavior would have a great influence on the Earth’ s climate.
The source of the sun’ s inconstancy is magnetism. Professor William Livingston has developed new theories about its magnetic nature.
"We don’ t yet know what causes sun spots, "he says, "but we now think they ’ re areas of high level magnetism that come up from the sun’ s interior. So strong is their magnetic pull that the highly ionized gas nearby is not able to transmit energy out. "As a result these areas send out less heat and light and thus appear from Earth to be almost dark irregular surface patches.
Sun
