CONT

Think of the Sun as a highly magnetic ball of gas. Following along magnetic field lines, giant loops of plasma can form that extend far outward into space from the Sun's glowing "surface," its photosphere. These loops of plasma are solar prominences, and they can measure many times larger than Earth's diameter.
