Solar prominence. Time-lapse Solar Dynamics Observatory (SDO) ultraviolet footage that includes a large solar prominence at upper left. The SDO is an Earth-orbiting spacecraft launched in 2010 by NASA and used to observe the Sun. Here, the Sun is seen at a wavelength of 304 angstroms (extreme ultraviolet). This channel shows areas where cooler, dense plumes of plasma (such as filaments and prominences) occur above the visible surface of the Sun, and are seen in the upper chromosphere and lower transition region. This footage covers a period of four hours on 16 April 2012. | |
