The heat is on ?! Our Solar Dynamics Observatory satellite captured a relatively small - see the Earth inset for scale - prominence hovering over the Sun’s surface on June 12-14 before breaking off into space. Prominences are clouds of solar material suspended above the Sun’s surface by the solar magnetic field – the same complex magnetism that drives solar events like flares and coronal mass ejections. The solar material in the prominence streams along the Sun’s magnetic field lines before it thins out and gradually breaks away from the solar surface.
