This incredible picture featuring a detached prominence off the limb of the Sun was taken by Alan Friedman.

 

"Alan used a filter that lets through only a very narrow wavelength of light emitted by hydrogen (called Hα for those of you keeping track at home), so this tracks the activity of gas on the solar surface. He also inverts the image of the solar disk (makes it a negative) to increase contrast. Somehow this adds a three-dimensional quality to the picture, and reveals an amazing amount of texture."
