Well, not really, but it is interesting.
The mystery of why temperatures in the solar corona, the sun’s outer atmosphere, soar to several million degrees Kelvin (K) –much hotter than temperatures nearer the sun’s surface–has puzzled scientists for decades. New observations made with instruments aboard Japan’s Hinode satellite reveal the culprit to be nanoflares.
Cool stuff. I get this question from my 8th graders every year. But how do I explain nanoflares?
