Question

Quizplus · Accepted Answer

Prominences and filaments are both dense, cooler plasma suspended in the Sun's corona, but the term "prominence" refers to those that can be seen extending away from the limb of the Sun, while "filament" refers to those that can be seen silhouetted against the disk of the Sun. Prominences and filaments are the same features of the Sun's atmosphere. Prominences are seen as bright structures extending off the solar limb during a solar eclipse or with the use of special filters. Filaments, on the other hand, are dark, filament-like structures seen in front of the solar disk, often in association with sunspots. Both are caused by the same phenomenon of charged particles interacting with magnetic fields in the Sun's atmosphere.
