False-colour optical photograph of an arch-like quiescent solar prominence. Prominences are bright clouds or filaments of incandescent gas which reach up from the Sun's chromosphere into the corona. They are of two types: eruptive and quiescent. Eruptive prominences,are in violent motion and may extend outward for more than 700,000 km above the Sun's surface. Quiescent prominences such as this are more stable. They are often arch shaped and may hang in the chromosphere for weeks before breaking up. They are best seen (as here) when jutting out from the Sun's limb | |
