Prominences are clouds of incandescent, ionized gas ejected from the Sun's surface. They are also some of the most dramatic phenomena in the solar system, the equivalent of thousand-mile-high storms that can rage for months. This time-lapse film shows active prominences of a few hours' duration. “Loop” prominences like this one, which seems to rise and fall back to the surface, are the aftermath of solar flares. Prominences are transparent in normal light and have to be viewed through special instruments that can detect the spectroscopic emission lines of hydrogen.
