APOD: Sun and Prominence

Prominence on the sun, such as these, can be seen from time to time on the edge of the sun's surface. This large prominence was seen in the week of March 4th 2014, and was seen to have simply been emitting light using hydrogen. These such prominence are clouds of solar gas that have been held in tact and suspended on the surface by the magnetic field of the Sun. The people whom have edited in a picture of Earth to proportionate the sizes of both the prominence and our Earth, showing that the prominence is in fact larger than the Earth. These prominence last about a month, and can emit a Coronal Mass Ejection, which sends hot gas throughout the solar system and causes Auroras on Earth.
