Fibrils Flower on the Sun
There are times the sun may resemble a rose, such as when a specific color of red light emitted by hydrogen. The pinkish color is seen on some regions of the solar chromosphere. The color-inverted image was taken in October 2014 and displays the active solar/sunspot region 2177 (which survived several days before evolving yet again) on the sun. The "petals" are actually magnetically confined tubes of hot plasma (known as fibrils - some of which extend longer than the diameter of the Earth). Due to the way this picture was taken, the central region fibrils are seen end-on and surrounding regions are filled with curved fibrils (huge plasma tubes seen over the Sun's edge- spicules,when in passive regions- mottles).
