Description
Solar activity, Solar Dynamics Observatory (SDO) ultraviolet image. 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 1700 angstroms (far ultraviolet). This channel shows a pattern of bright areas highlighting concentrations of magnetic field lines. Particularly intense concentrations, such as sunspots, are shown as black areas. The layers of the Sun images shown here are the temperature minimum and photosphere. Image obtained on 23 January 2012, during a period of solar activity.
