One year of solar activity, Solar Dynamics Observatory (SDO) ultraviolet composite image. The activity seen here covers the period 11 January 2015 to 21 January 2016, combining 23 images. The image shows that the equatorial regions of the Sun are the most active. The SDO is an Earth-orbiting spacecraft launched in 2010 by NASA and used to observe the Sun. Here, the Sun and its atmosphere (not seen in visible light) is seen at a wavelength of 171 angstroms (extreme ultraviolet), obtained with the Atmospheric Imaging Assembly (AIA) sensor.
