Solar prominence

If you blow up the picture you may think it's a bush fire over the hilltop and a nice flame to light your cigar with, but it's actually a bit different. You are looking at an image from the sun through a solar telescope and the flames on the edge are called prominences. Prominences are enormous clouds of hydrogen (which make up the bulk of the sun basically) held together by solar magnetic fields.

WARNING! DON'T TRY TO SEE THIS FOR YOURSELF BY LOOKING DIRECTLY INTO THE SUN, WITH OR WITHOUT TELESCOPE OR BINOCULARS! IF YOU DO YOU WILL GET BLIND!!
