Solar flares. Time-lapse Solar Dynamics Observatory (SDO) ultraviolet footage of an active region of the Sun that produced four X-class flares (largest class) in two days (13-15 May 2013). The flares are seen as bright flashes. 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 was obtained in May 2013. | |
