filaments on the Sun

  at http://phys.org/print352105901.html … we have an image of giant filaments on the face of the Sun. Filaments are said to be cooler clouds of solar material suspended above the Sun's surface by powerful magnetic forces. Filaments can float for days without altering a great deal. They can erupt, releasing material that then rains back down on the surface of the Sun – or is blasted into space. It then becomes a moving cloud of plasma, a coronal mass ejection event (CME).
