Arching prominence

Arching prominence – This bulbous solar prominence was taken 11 April 2003 by the EIT 304 instrument. This one extends over 30 times the size of earth out from the Sun. Prominences, which consist of cooler plasma, are suspended above the Sun by magnetic forces and can last from hours to weeks.
