Modern telescopes and satellites have helped us measure the blazing hot temperatures of the sun from afar. Mostly the temperatures follow a clear pattern: The sun produces energy by fusing hydrogen in its core, so the layers surrounding the core generally get cooler as you move outwards--with one exception. Two NASA missions have just made a significant step towards understanding why the corona--the outermost, wispy layer of the sun's atmosphere --is hundreds of times hotter than the lower photo...
