| Description: |
An elongated solar prominence rose up above the sun's surface and slowly unraveled on Feb. 3, 2016, as seen by NASA's Solar Dynamics Observatory, or SDO. 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. [Source: NASA Goddard Space Flight Center]
