Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares -- a constant peppering of impulsive bursts of heating, none of which can be individually detected -- provide the mysterious extra heat.
