Star of Wonder
Image by TRACE, NASA
It may look wild, but this image of the solar surface, captured by a NASA satellite called TRACE on September 18, 2000, was described by scientists as "a quiet day on the sun." In other words, spectacular loops but no flares or CMEs. Even as satellites like TRACE and SOHO have brought new understanding of solar dynamics, the sun holds on to many secrets. Our stormy star is, in the words of one solar physicist: "Complicated, mysterious, and beautiful."
