Prominences occur on the surface of which astronomical object?

Not too difficult as the picture is of the sun.

INCASE YOU'RE WONDERING: A solar prominence is anchored to the sun; the arch does not separate and go into space. A solar flare, though, will travel through space, since it is a release of energy. A solar prominence can break down and release a solar flare, but that does not always happen.

shellawk, thanks for the info

The pic kinda gives it away!!

Mythagoman, My thoughts exactly.

Of course, nobody's proven any of that because it's too hot a job.
