A solar prominence is a large bright feature located in the solar corona. While the corona consists of extremely hot gases which do not emit much visible light, prominences contain much cooler gas, similar in composition to that of the chromosphere. A prominence forms over timescales of about a day, and may persist in the corona for several weeks. Many prominences break apart and give rise to coronal mass ejections.
Despite decades of study, the mechanism by which prominences form is not yet well understood. Theories have not satisfactorily explained how prominences can remain stable for such a long time when they are much denser than their surroundings.
