Scientists Wonder What Weakest Solar Cycle in 50 Years Means For Earth

"The surface of the sun has been surprisingly calm of late — with fewer sunspots than anytime in in the last century — prompting curious scientists to wonder just what it might mean here on Earth."

"Sunspots have been observed for millennia — first by Chinese astronomers and then, for the first time with a telescope, by Galileo in 1610.

The sunspots appear in roughly 11-year cycles — increasing to a daily flurry and then subsiding drastically, before amping up again.

But this cycle — dubbed cycle 24 — has surprised scientists with its sluggishness."
