Plasma Dancing Off the Sun

The Solar Dynamics Observatory captured some plasma streaming off the Sun, doing a quick dance, and diving back into the surface. This video zooms into an active region over two days (Apr. 30 – May 2, 2011). The cloud of ionized gas, or plasma that comes off the Sun is caused by an active, erupting sunspot. Why does the plasma return instead of streaming off into space? Magnetic forces are pulling the material along magnetic field lines on the Sun, and the plasma follows the Sun’s magnetic fields as it flies outwards, and either returns to the Sun or goes out into space. Here, the plasma returned. What you are seeing is ionized Helium at about 60,000 degrees C. in extreme ultraviolet light.
