Scientists Discover Way to Predict Sunspots

Researchers say they can provide 48 hours warning

(Newser) - Maybe we'll eventually be able to cross off solar flares as a possible way the world ends. Scientists at Stanford say they've developed a system to predict dangerous sunspots two days before they erupt, reports the San Francisco Chronicle . Using satellite data, they can detect the rumblings of... More »
